Embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)
FIG. 1 is a diagram showing an example of the configuration of a data processing device 1 according to the present embodiment. In FIG. 1, only functional blocks related to this embodiment are extracted and shown. The data processing device 1 includes a holding unit 2 that holds a plurality of parts, an information unit 3 that holds information about the parts, and an output that outputs input data or the output of the parts in the previous order to a specific part related to the data. Either part 4 is provided. In this embodiment, it is assumed that the component held by the holding unit 2 is a FASA (Flexible Access System Architecture) application, which will be described later. A FASA application is a software component that implements functions that differ for each service or communication carrier using a generalized input/output interface (eg, FASA application API). In this embodiment and other embodiments, software components such as FASA applications are exemplified as components held by the holding unit 2, but components held by the holding unit 2 may be software components other than FASA applications, such as FASA platform (FASA ) may be a software component, or may be hardware such as an external hardware component, or a component containing hardware.

Hereinafter, the processing performed by the data processing device 1 will be explained by illustrating a plurality of operation examples (first operation example to sixth operation example).
(First operation example)
As a first operation example, the data processing device 1 sequentially calls parts (for example, a FASA application) that are associated with the data content, and stores data or previous parts in the called parts. Print the output. Here, the component in the previous order represents a component that was called before the data processing device 1 called the Tth time (the currently called component) (for example, a component that was called the T-1st time). .

In the first operation example, the information unit 3 holds a list related to processing (hereinafter referred to as "processing list") as information regarding parts. In the processing list, data processing is associated with a component that processes the data. The output unit 4 sequentially calls parts (FASA applications) that process the data based on the input data and the processing list, and outputs data or the output of the previous part to the called parts. Here, the data to be output may be all the input data. In this case, since a group of data is passed to the component all at once, there is an effect that the group of data is not scattered and becomes easier to understand.

Further, the output unit 4 may output only data related to processing to the component without outputting data that is not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. Particularly, when the output unit 4 outputs actual data to a component rather than an index indicating a data storage location, etc., the output unit 4 has the effect of reducing the amount of data to be output. It is preferable that the processing be performed in parallel using pipeline processing or the like.

Further, the processing list may be separately held in the information unit 3 for each parallel process, or may be shared by multiple processes. If it is held separately, it is easy to record the data distribution status for each process list, and if it is shared, it is desirable that the information unit 3 separately maintains a record regarding the data distribution status for each process. Note that although the output of actual data has been mainly explained here, the output unit 4 also provides information indicating the storage location of the data (for example, the address of the data storage destination, etc.) or the storage location of the output of the previous component. The information may be output and the data may be processed on a storage location where each component is specified based on the output information.
Although the call is exemplified using a software component such as a FASA application, it may also be a FASA platform (FASA base). The same applies to the following explanation.

(Second operation example)
As a second operation example, the data processing device 1 sequentially calls a plurality of parts (FASA applications) associated with the data content, and the called part receives data or the previous part. Print the output. In the second operation example, the information unit 3 holds, as information regarding parts, a list (hereinafter referred to as a "processing chain list") that shows parts related to processing in the order in which they are processed. In the processing chain list, data processing is associated with parts indicated in the order in which the data is processed. The output unit 4 sequentially calls the parts that process the data based on the input data and the processing chain list, and outputs the data or the output of the previous part to the called parts.

Specifically, the output unit 4 first refers to the processing chain list and identifies the component that processes the input data first. Next, the output unit 4 calls the specified part and outputs data or the output of the previous part to the called part. When the data processing by the called component is completed, the output unit 4 refers to the processing chain list and identifies the component that will process the data next. Next, the output unit 4 calls the specified part and outputs data or the output of the previous part to the called part. Thereafter, the output unit 4 repeats calling the parts and outputting the data or the output of the previous parts according to the processing chain list until the processing of the input data is completed.

Here, the data to be output may be all the input data. In this case, since a group of data is passed to the component all at once, there is an effect that the group of data is not scattered and becomes easier to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data that is not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. Particularly, when the output unit 4 outputs actual data to a component rather than an index indicating a data storage location, etc., the output unit 4 has the effect of reducing the amount of data to be output. It is preferable that the processing be performed in parallel using pipeline processing or the like.

Furthermore, the processing chain list may be separately held in the information unit 3 for each parallel process, or may be shared by multiple processes. If it is held separately, it is easy to record the data distribution status for each processing chain list, and if it is shared, it is desirable that the information unit 3 separately maintains a record regarding the data distribution status for each process. Note that although the output of actual data has been mainly explained here, the output unit 4 also provides information indicating the storage location of the data (for example, the address of the data storage destination, etc.) or the storage location of the output of the previous component. The information may be output and the data may be processed on a storage location where each component is specified based on the output information.
Although the call is exemplified using a software component such as a FASA application, it may also be a FASA platform (FASA base). The same applies to the following explanation.

(Third operation example)
As a third operation example, the data processing device 1 performs a predetermined process based on at least one of the history of the data output source (for example, the last output source, the penultimate output source, and the previous one) and the content of the data. The parts specified in the correspondence table are sequentially called, and data or the output of the previous part is output to the called parts. Here, the output source is an external device, inside the ONU or OLT, or the FASA platform or FASA application. In the third operation example, the information unit 3 holds a correspondence table related to processing as information regarding parts. The correspondence table associates at least one of data processing and data output sources with parts that process data. Note that it is not limited to the correspondence table.

The output unit 4 is a component that processes data based on at least one of the history of the data output source (for example, the last output source, the second to last and the previous one), the content of the data, and a correspondence table. (FASA application) is called one after another, and data or the output of the previous part is output to the called parts. The specific process will be explained.

(When the data output source and the part that processes the data are associated in the correspondence table) In this case, when data is input, the output unit 4 refers to the correspondence table and outputs the input data. Identify the parts associated with the output source. Then, the output unit 4 outputs data for the specified component or output of the component in the previous order.

(If the data content and the parts that process the data are associated in the correspondence table)
In this case, when the data is input, the output unit 4 refers to the correspondence table and identifies the component that is associated with the content of the input data. Then, the output unit 4 outputs data for the specified component or output of the component in the previous order.

(If the data output source, data content, and data processing parts are associated in the correspondence table)
In this case, when the data is input, the output unit 4 refers to the correspondence table and identifies a component that is associated with both the output source of the input data and the content of the data. Then, the output unit 4 outputs data for the specified component or output of the component in the previous order.

Here, the data to be output may be all the input data. In this case, since a group of data is passed to the component all at once, there is an effect that the group of data is not scattered and becomes easier to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data that is not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. Particularly, when the output unit 4 outputs actual data to a component rather than an index indicating a data storage location, etc., the output unit 4 has the effect of reducing the amount of data to be output. It is preferable that the processing be performed in parallel using pipeline processing or the like.

Further, the correspondence table may be separately held in the information unit 3 for each parallel process, or may be shared by multiple processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the information unit 3 separately maintains records regarding the data distribution status for each process. Note that although the output of actual data has been mainly explained here, the output unit 4 also provides information indicating the storage location of the data (for example, the address of the data storage destination, etc.) or the storage location of the output of the previous component. The information may be output and the data may be processed on a storage location where each component is specified based on the output information.
Although the call is exemplified using a software component such as a FASA application, it may also be a FASA platform (FASA base). The same applies to the following explanation.

(Fourth operation example)
As a fourth operation example, the data processing device 1 performs a predetermined process based on at least one of the history of the data output source (for example, the last output source, the penultimate output source, and the previous one) and the content of the data. The parts specified in the correspondence table are sequentially called and data is output to the called parts. Here, the data output source is an external device, inside the ONU or OLT, or the FASA platform or FASA application. In the fourth operation example, the information unit 3 holds a correspondence table related to processing as information regarding parts. The correspondence table associates at least one of data processing and data output sources with parts that process data. Note that it is not limited to the correspondence table.

The output unit 4 is a component that processes data based on at least one of the history of the data output source (for example, the last output source, the second to last and the previous one), the content of the data, and a correspondence table. (FASA application) is called one after another, and data or the output of the previous part is output to the called parts.

Here, the data to be output may be all the input data. In this case, since a group of data is passed to the component all at once, there is an effect that the group of data is not scattered and becomes easier to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data that is not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. Particularly, when the output unit 4 outputs actual data to a component rather than an index indicating a data storage location, etc., the output unit 4 has the effect of reducing the amount of data to be output. It is preferable that the processing be performed in parallel using pipeline processing or the like.

Further, the correspondence table may be separately held in the information unit 3 for each parallel process, or may be shared by multiple processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the information unit 3 separately maintains records regarding the data distribution status for each process. Furthermore, a Forwarding-Engine, SW, or the like may be used as the output unit 4 that transfers data to the component. The use of Forwarding-Engine, SW, etc. is particularly suitable when the data is in a predetermined frame format. Note that although the output of actual data has been mainly explained here, the output unit 4 also provides information indicating the storage location of the data (for example, the address of the data storage destination, etc.) or the storage location of the output of the previous component. The information may be output and the data may be processed on a storage location where each component is specified based on the output information. For the destination (storage destination), if the output unit 4 instructs the next component for each process, it will take time to refer to the Table (correspondence table)/list one by one, but there is no need to convey destination information to the component, and the TAG (described later) This also has the effect of making it unnecessary.
Although the call is exemplified using a software component such as a FASA application, it may also be a FASA platform (FASA base). The same applies to the following explanation.

(Fifth operation example)
As a fifth operation example, the data processing device 1 specifies the data output destination based on the Tag, sequentially calls the specified predetermined parts, and outputs data or the output of the previous part to the called parts. Here, the data output source is an external device, inside the ONU or OLT, or the FASA platform or FASA application. In the fifth operation example, the output unit 4 specifies the data output destination based on the Tag, sequentially calls the specified predetermined parts, and outputs data or the output of the previous part to the called parts.

The Tag may be given, for example, before inputting the FASA platform or at the time of inputting the FASA platform or a predetermined part (FASA application). A plurality of Tag destinations may be assigned sequentially, or when data is divided and processed, it may be assigned for each division. Tags may be assigned to all destinations or to multiple destinations (for example, up to several destinations). When attaching multiple tags, it is desirable for the output unit 4 to remove the transferred tag so that the parts whose data has been transferred can be identified, or to attach a mark indicating that the data has been transferred.

Although the output of actual data has been mainly explained here, the output unit 4 outputs information indicating the data storage location (for example, the address of the data storage destination, etc.), and each component Data may be processed on the specified storage location. When attaching a tag to a part, it is necessary to convey information for attaching the tag to the part. As for how to convey the message, the function that attaches the tag (for example, the attaching unit) may refer to a list such as a table every time it attaches the tag, or every predetermined number of times, or every time a predetermined period of time elapses, or the function that attaches the tag (for example, It may be referenced or read at the time of updating such as replacement/addition/deletion of FASA application) or startup/reboot/Liveupdate of components (FASA application) or infrastructure. Note that the function (for example, an attaching unit) for attaching a tag may be provided in the data processing device 1 or may be provided in an external device connected to the data processing device 1.

When adding in a common area such as the SW or CONT version, the notification to the place to be added is the same as above. When assigning tags to Forwarding-Engine, SW, etc., when replacing/adding/deleting components (FASA applications) to Forwarding-Engine, etc., or updating components (FASA applications) or platforms such as starting/rebooting/Liveupdate, etc. You may also set it.

Here, the data to be output may be all the input data. In this case, since a group of data is passed to the component all at once, there is an effect that the group of data is not scattered and becomes easier to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data that is not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. Particularly, when the output unit 4 outputs actual data to a component rather than an index indicating a data storage location, etc., the output unit 4 has the effect of reducing the amount of data to be output. It is preferable that the processing be performed in parallel using pipeline processing or the like.

Furthermore, the table or list may be separately held in the information unit 3 for each parallel process, or may be shared by multiple processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the information unit 3 separately maintains records regarding the data distribution status for each process. Furthermore, a Forwarding-Engine, SW, or the like may be used as the output unit 4 that transfers data to the component. The use of Forwarding-Engine, SW, etc. is particularly suitable when the data is in a predetermined frame format. Note that although the output of actual data has been mainly explained here, the output unit 4 also provides information indicating the storage location of the data (for example, the address of the data storage destination, etc.) or the storage location of the output of the previous component. The information may be output and the data may be processed on a storage location where each component is specified based on the output information.
Although the call is exemplified using a software component such as a FASA application, it may also be a FASA platform (FASA base). The same applies to the following explanation.

(Sixth operation example)
As a sixth operation example, the data processing device 1 associates data output from an external device, inside the ONU or OLT, or from a FASA platform or component (FASA application) via the FASA-API, or an address indicating the storage location of the data. Based on the Tag, the component (FASA application) corresponding to the Tag performs processing. For example, a component (FASA application) scans the Tag during the processing time allocated to the component and processes the data to be processed by the component or the output of the previous component.

The Tag may be given, for example, before inputting the FASA platform or at the time of inputting the FASA platform or a predetermined part (FASA application). A plurality of Tag destinations may be assigned sequentially, or when data is divided and processed, it may be assigned for each division. Tags may be assigned to all destinations or to multiple destinations (for example, up to several destinations). When attaching multiple tags, it is desirable for the output unit 4 to remove the transferred tag so that the parts whose data has been transferred can be identified, or to attach a mark indicating that the data has been transferred.

Although the output of actual data has been mainly explained here, the output unit 4 outputs information indicating the data storage location (for example, the address of the data storage destination, etc.), and each component Data may be processed on the specified storage location. When attaching a tag to a part, it is necessary to convey information for attaching the tag to the part. As for how to convey the message, the function that attaches the tag (for example, the attaching unit) may refer to a list such as a table every time it attaches the tag, or every predetermined number of times, or every time a predetermined period of time elapses, or the function that attaches the tag (for example, It may be referenced or read at the time of updating such as replacement/addition/deletion of FASA application) or startup/reboot/Liveupdate of components (FASA application) or infrastructure.

When adding in a common area such as the SW or CONT version, the notification to the place to be added is the same as above. When assigning tags to Forwarding-Engine, SW, etc., when replacing/adding/deleting components (FASA applications) to Forwarding-Engine, etc., or updating components (FASA applications) or platforms such as starting/rebooting/Liveupdate, etc. You may also set it.

Here, the data to be output may be all the input data. In this case, since a group of data is passed to the component all at once, there is an effect that the group of data is not scattered and becomes easier to understand. Further, the output unit 4 may output only data related to processing to the component without outputting data that is not processed by the component to the component. In this case, there is an effect that the amount of output data can be reduced. Particularly, when the output unit 4 outputs actual data to a component rather than an index indicating a data storage location, etc., the output unit 4 has the effect of reducing the amount of data to be output. It is preferable that the processing be performed in parallel using pipeline processing or the like.

Furthermore, the table or list may be separately held in the information unit 3 for each parallel process, or may be shared by multiple processes. If it is held separately, it is easy to record the data distribution status for each correspondence table, and if it is shared, it is desirable that the information unit 3 separately maintains records regarding the data distribution status for each process. Furthermore, a Forwarding-Engine, SW, or the like may be used as the output unit 4 that transfers data to the component. The use of Forwarding-Engine, SW, etc. is particularly suitable when the data is in a predetermined frame format. Note that although the output of actual data has been mainly explained here, the output unit 4 also provides information indicating the storage location of the data (for example, the address of the data storage destination, etc.) or the storage location of the output of the previous component. The information may be output and the data may be processed on a storage location where each component is specified based on the output information.
Although the call is exemplified using a software component such as a FASA application, it may also be a FASA platform (FASA base). The same applies to the following explanation.

The data processing device 1 makes it possible to exchange data between the modules shown in FIG. 8 by performing any one of the first to sixth operations described above. Note that although the explanation has been given above using a component provided in the OLT (FASA application) as an example, data may be exchanged by software constituting the FASA platform, the FASA platform itself, an ONU, another OLT, or an external device.

The data processing device 1 is, for example, a communication device that performs communication with other communication devices using signals such as optical signals passing through a communication network such as an optical fiber network such as a PON. This communication device is, for example, an OLT (Optical Line Terminal). The communication device may be, for example, an OSU (Optical Subscriber Unit). The communication device may be, for example, a combination of an OLT with or without a switch unit (SW) for switching optical signals and another switch unit (SW). The communication device may be, for example, a combination of an OLT and an ONU (Optical Network Unit). A communication device may include multiple devices. Further, other communication devices such as an ONU, a MUX (multiplexer), a DEMUX (demultiplexer), or a switch may be used.

Next, as an example, the operation etc. will be illustrated on the premise that the communication device as the data processing device 1 is an OLT of a PON such as a TWDM (Time and Wavelength Division Multiplex)-PON system that is compliant with ITU-T recommendations. do. Although the TWDM-PON is used here, the PON may be a PON other than the TWDM-PON that complies with ITU-T recommendations. For example, the PON may be a PON compliant with IEEE standards, such as GE (Gigabit Ethernet (registered trademark))-PON, 10 GE-PON, or the like. The TC (Transmission Convergence) layer and the PMD (Physical Medium Dependent) layer are the same as the corresponding layers in the standard.

A communication device includes a component of hardware or software or a combination thereof, or a componentized function. For example, a communication device may include an application (for example, a FASA application) that is a software component that implements functions that differ for each service or for each communication carrier using a generalized input/output interface (for example, a FASA application API); Fundamental components of access network equipment (for example, FASA infrastructure) that provide the application with the general-purpose input/output interface and provide functions that do not require changes according to services or requests because they are standardized. ). Here, by using a general-purpose input/output interface, functions can be easily added or replaced, and various requested services can be provided flexibly and quickly. Note that in this specification, an application is also referred to as an "app."

For example, the exchange between components is via the middleware section 120 described later, but it is also possible to use a unique transfer path or means of the communication device, or use OpenFlow, Netconf/YANG, SNMP (Simple Network Management Protocol), etc. Standardized means may also be used.

Furthermore, communication between components may be through any route such as internal wiring, a backboard, an OAM section, a main signal line, a dedicated wiring, an operation system, a controller, or a control panel. If the communication between components is directly terminated and input, it may be encapsulated in the OAM section or main signal. Communication between parts may be terminated at any point and input via a route such as internal wiring, backboard, OAM section, main signal line, dedicated wiring, operation system, controller, or control panel. . When using an OAM section or main signal line, it is desirable to encapsulate it in the OAM section or main signal line. If the main signal line is passed through, it is desirable to distribute it at the OSU or at another switch section.

In this embodiment, the communication device 51 further includes an interface for receiving software components in an application such as a FASA application or a platform such as a FASA infrastructure.

The interface relates to, for example, a list or table related to data exchange. If a component (FASA application) holds them, this is an interface that conveys them in their entirety to the component (FASA application). The FASA platform holds them, and when a component (FASA application) refers to them, it is an interface for reference. When a Tag, mark, or address chain is used, an interface related to the Tag is used where the Tag, mark, or address chain to be used is assigned, interpreted, or processed. Further, the interface is used when a FASA application changes or modifies a tag or mark. Further, when the progress history of a data component (FASA application) is used, the interface is an interface that notifies the destination according to the history.

(Embodiment 1-1)
In Embodiment 1-1, the configuration of a communication device that constitutes a communication system used in TWDM-PON will be described. The communication device described in Embodiment 1-1 is used as the data processing device 1 shown in FIG. Hereinafter, the first to sixth examples will be described as examples of the architecture of the communication device. The architecture of the communication devices constituting the communication system may be architectures other than the first to sixth examples described below. For example, the software section of the communication device in the first to sixth architecture examples may be a hardware section.

(First example of architecture)
FIG. 2 is a diagram illustrating a first example of the architecture of a communication device. In the first example of the architecture, the communication device includes a non-general-purpose device-dependent section 110 whose operation depends on the device, a middleware section 120 that hides differences in hardware and software of the device-dependent section 110, and a device-dependent section whose operation depends on the device. It also includes a general-purpose device-independent application section 130 that does not require a device. Therefore, the device-dependent unit 110 (vendor-dependent unit) is a functional unit that depends on the standard to which the device of the communication device complies and the manufacturer of the device. In other words, the device-dependent unit 110 has low compatibility with other communication devices, and cannot be used as is in newly manufactured communication devices (particularly devices that comply with different standards or are manufactured by different vendors). The device dependent unit 110 executes one or more functions provided in the network device.

Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device complies or the manufacturer of the device. In other words, the device-independent application unit 130 has great compatibility with other communication devices, and can be used as is in newly manufactured communication devices (particularly devices that comply with different standards or are manufactured by different vendors). Specific examples of applications provided in the device-independent application section 130 include an application that performs setting processing in a network device, an application that performs setting change processing, an application that performs algorithm processing, and the like.

The middleware section 120 and the device-independent application section 130 are connected via a device-independent API 21. The device-independent API 21 is an input/output IF that is device-independent.

The device dependent unit 110 includes, for example, a hardware unit 111 (PHY), a hardware unit 112 (MAC), a software unit 113, and an OAM (Operation Administration and Maintenance) unit 114. The hardware section 111 (PHY), the hardware section 112 (MAC), the software section 113, and the OAM section 114 are connected to the middleware section 120 via a device-dependent API 23. The device-dependent API 23 is an input/output IF that depends on the device. The device dependent unit 110 further includes an NE (Network Element) management/control unit 115 . The NE management/control unit 115 and middleware unit 120 are connected via a device-dependent API 25. The device-dependent API 25 is an input/output IF that depends on the device.

What functions are to be included in the device-dependent section 110 or the device-independent application section 130 are determined by limitations originating from the processing for realizing the middleware section 120 or the device-independent application section 130, such as limitations arising from the processing ability of the software. In addition to the restrictions, the restrictions may be determined based on the update frequency of functions, the importance of extended functions, and the like. Thereby, the communication device can easily and flexibly and quickly add an extended function section (original function section) by the device-independent application section 130, and can provide communication services in a timely manner.

For example, functions that are updated frequently, such as priority processing of main signals and DBA (Dynamic Bandwidth Assignment) that improves line utilization efficiency, or functions that contribute to communication service differentiation are prioritized, and the device-dependent unit 110 or device-independent unit 110 You may decide to use the application section 130. Furthermore, the device-independent application section 130 may be selected from devices that have a small difference in at least one of the standards, generations, methods, systems, device types, and manufacturing vendors that the devices to be shared are compliant with.

Any feature of a compliant standard, generation, method, system, device type, or manufacturing vendor, even if it is not optimal for the compliant standard, generation, method, system, device type, or manufacturing vendor. In order to generalize the functions, a common IF may be used to perform the functions. The common IF may include IFs and parameters that are not used in any of the standards, generations, systems, systems, device types, and manufacturing vendors that the device-dependent unit 110 complies with.

The middleware unit 120 shown in FIG. 2 and FIG. 3 (described later), the driver of the device dependent unit 110 shown in FIG. 4 (described later) and FIG. 5 (described later), and the device dependent application unit 150 ( A conversion function unit that converts IFs, parameters, etc. to correspond to the device-dependent unit 110, and a function unit that automatically configures settings in response to missing IFs, parameters, etc. are further added to at least one of the vendor-dependent application unit). You may prepare.

The device dependent unit 110 shown in FIG. 2 includes a hardware unit 111 (PHY), a hardware unit 112 (MAC), and a software unit 113. The hardware unit 111 (PHY) executes processing from the physical layer to optical transmission/reception related processing (PHYsical sublayer processing). The hardware unit 112 (MAC) executes MAC (Media Access Control) processing. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) depend on the standards they comply with and the manufacturing vendor. The software unit 113 executes device-dependent drivers, firmware, applications, and the like.

The hardware section 111 (PHY) and the hardware section 112 (MAC) of the device dependent section 110 may include a general-purpose server, a layer 2 switch, etc. in addition to these. The device dependent unit 110 does not need to include the hardware unit 112 (MAC). The device dependent unit 110 may not include a part of the hardware unit 111 (PHY). For example, the device-dependent unit 110 may include only optical-related functions without providing low-level signal processing such as modulation/demodulation signal processing, forward error correction (FEC), code/decoding processing, and encryption processing. good. The device-dependent unit 110 does not need to include a PCS (PHYsical Coding Sublayer), which is a part that encodes data. The device dependent unit 110 does not need to include a PMA (Physical Medium Attachment) that serializes data and a PCS. The device dependent unit 110 may not include a PMD that connects to a physical medium. The device-dependent unit 110 may be configured to: The software section 113 may not be provided.

The device-independent application section 130 includes, for example, extended function sections 131-1 to 131-3 (extended function A, extended function B, and extended function C in FIG. 2), a basic function section 132, and a management/control agent section. 133. The management/control agent unit 133 exchanges data from an EMS (Element Management System) 140.

In the figure, the EMS 140 and an external device 160 are connected to the device-independent application section 130 via the middleware section 120, but the EMS 140 and the external device 160 are not necessarily connected to the device-independent application section 130 via the middleware section 120. There is no need to do so. The EMS 140 and the external device 160 may be appropriately connected to the middleware section 120 as necessary, or may be directly connected to the device-independent application section 130. Furthermore, although the expression "connection via the middleware section 120" is used, this expression is expressed from the viewpoint of the device-independent application section 130. In reality, device-independent applications are connected to each other via the middleware unit 120 after connection by hardware.

Hereinafter, items common to the extended function sections 131-1 to 131-3 will be referred to as "extended function section 131" with part of the reference numerals omitted. The EMS 140 is, for example, a controller of an NE. Note that the device-independent application section 130 may not include any one of the extended function section 131, the basic function section 132, and the management/control agent section 133, or the management/control agent section 133 may include the basic function section 132. Alternatively, the management/control agent section 133 may be included in the basic function section 132 or the middleware section 120.

The device-independent application section 130 may further include components other than the extended function section 131, the basic function section 132, and the management/control agent section 133. For example, if the extended function section 131 is not required, the device-independent application section 130 may not include the extended function section 131. Further, the device-independent application section 130 may include one or more extended function sections 131.

It is preferable that the extended function section 131 can be independently added, deleted, replaced, or changed without having unnecessary effects on other functions. For example, the extended function unit 131 may be added, deleted, replaced, or changed as appropriate when the extended function unit 131 is required to perform multicast service or power saving support in accordance with service requirements. .

The basic function section 132 may be included in the device-independent application section 130 as part of the extended function section 131, or may be replaced by a function section lower than the middleware section 120. When the extended function section 131 includes the basic function section 132, the device-independent application section 130 does not need to include the basic function section 132. When a functional unit lower than the middleware unit 120 replaces the basic functional unit 132, the device-independent application unit 130 does not need to include the basic functional unit 132. If the extended function section 131 includes the basic function section 132 and a function section lower than the middleware section 120 replaces the basic function section 132, the device-independent application section 130 does not need to include the basic function section 132.

The management/control agent unit 133 does not need to input/output to/from the EMS 140 when performing automatic settings according to predetermined settings without receiving communication from the EMS 140 . Furthermore, if the management/control agent section 133 does not have a management setting function and the other device-independent application section 130, basic function section 132, or device-dependent section 110 has a management setting function, the device-independent application section 130 The management/control agent section 133 may not be provided.

The EMS 140 and the device-independent application unit 130 may directly input and output information. Furthermore, the device-dependent unit 110 may be replaced by the NE management/control unit 115 and the device-dependent application unit 150 (see FIG. 3 described later and FIG. 5 described later), which is a lower functional unit of the NE management/control unit 115. good.

The management/control agent unit 133 does not need to input/output information to/from the EMS 140 when automatically setting according to predetermined settings. Furthermore, if the management/control agent unit 133 does not have a management setting function and other device-independent application units 130, basic function unit 132, or device-dependent unit 110 have management setting functions, the device-independent application unit 130 does not have the management setting function. - The control agent unit 133 may not be provided. The EMS 140 and the device-independent application unit 130 may directly input and output information.

An example of input/output between the device-independent application section 130 and the device-dependent section 110 is as follows.
For example, the DBA application section and the protection application section mutually input and output information with an embedded OAM engine of the TC layer. The DWBA (Dynamic Wavelength and Bandwidth Assignment) application and the ONU registration authentication application section mutually input and output information with the PLOAM engine of the TC layer. The power saving application unit inputs and outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD (Multicast Listener Discover) proxy application unit inputs and outputs information to and from the L2 function unit. The low speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functional units operate the XGEM framer (XGPON Encapsulation Method Framer) and encryption. Here, DWBA and DBA may be separate, integrated, or combined. For example, the management/control agent unit 133 is an application unit for maintenance and operation functions, and inputs/outputs information to/from the EMS 140, which is an NE controller or the like for the NE management/control unit 115.

Note that the implementation of the device-independent application unit 130 may be prioritized. For example, the management/control agent unit 133 has the highest priority. The order of priority below the second priority is, for example, DBA application, DWBA application, power saving application, ONU registration authentication application, MLD proxy application, protection application, and low speed monitoring application (OMCI).

The device-independent application unit 130 determines the device vendor, system, device type, and device generation, such as ITU-T G. TWDM-PON compliant with 989 series and ITU-T G.989 series. XG-PON compliant with 987 series and ITU-T G. G-PON compliant with 984 series and ITU-T G.984 series. This is an application that operates independently of B (Broadband) PON that conforms to the 983 series. The device-independent application unit 130 detects differences between device vendors, systems, device types, and device generations, such as 10GE-PON compliant with IEEE802.3av and IEEE1904.1, and GE-PON compliant with IEEE802.3ah. This is an app that works regardless of the situation.

Applications of the extended function unit 131 include applications for driving functions for some vendors, methods, types, and generations through the device-independent API 21, and applications for devices of some vendors, methods, types, and generations. It may also include an app that drives the functionality provided for.

The management/control agent section 133 inputs/outputs the EMS 140 and the middleware section 120 . The middleware section 120 inputs and outputs NE management information and control information to and from the NE management/control section 115. The NE management/control unit 115 may directly send/receive NE management information and control information to/from the EMS 140 without going through the middleware unit 120, or may send/receive NE management information and control information via the management/control agent unit 133. It may be sent and received.

The middleware section 120 inputs and outputs information via the device-independent application section 130 and device-independent API 21. The middleware section 120 inputs and outputs information to and from the OAM section 114, driver, firmware, hardware section 111 (PHY), or hardware section 112 (MAC) of the device dependent section 110 via the device dependent API 23. The middleware unit 120 outputs the input information as is or in a predetermined format. For example, if the output destination is each section of the device-independent application section 130, the middleware section 120 converts the information into the input format of each section of the device-independent API 21. If the output destination is the OAM unit 114, driver, firmware, hardware unit 111 (PHY), or hardware unit 112 (MAC) of the device dependent unit 110, the middleware unit 120 outputs the device dependent API 23 in the format input to each. The information is sent to the output destination after being converted into a format or after being terminated and subjected to predetermined processing.

During input, the middleware unit 120 deletes unnecessary input information for each input destination, and if there is insufficient information, it can collect and supplement it via other device-independent APIs 21 and device-dependent APIs 23. desirable. Further, when inputting to the middleware unit 120, the information may be broadcast or multicast to be simultaneously notified to related applications and the like.

In FIG. 2, the middleware section 120 and the device-dependent section 110 are illustrated as a single unit, but each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may perform input/output across processors and hardware using inter-processor communication or the like. The device-independent application section 130 or the device-independent application section 130 may be placed in the user space on a single processor as an execution program such as a DLL (Dynamic Link Library), or may be placed in the user space on a single processor. It may be placed in user space.

Furthermore, the device-independent application section 130 may be placed in the kernel space after securing an input/output IF such as an API, or may be placed together with the middleware section 120 that has an IF that can be independently replaced with firmware, etc. Alternatively, it may be incorporated into firmware or the like and recompiled. Any combination of user space and kernel space may be used for each device-independent application unit 130.
The device-independent application unit 130 corresponding to the same function may be implemented in both user space and kernel space. In this case, for example, one may be selected by switching, both may be processed in cooperation, or only one may perform actual processing. The same applies to the software of the device dependent unit 110.

Preferably, the more high-speed processing is required, such as main signal processing, DBA processing, and low-layer signal processing, the more high-speed processing is expected with less overhead, although there is a trade-off with scalability and immediacy of replacement. It is desirable to incorporate it into the kernel space or firmware. The processor in which the device-dependent application section 150 (see FIG. 3 and FIG. 5, which will be described later) is placed is also not suitable for implementation, from the viewpoint of restrictions on buses and speeds due to inter-processor communication, and the impact on other programs due to occupancy of communication paths. It is desirable to place it in the user space, kernel space, or firmware of the processor that performs the processing or a processor near it. However, in order to reduce the capacity of a processor that performs actual processing or a processor in its vicinity, the communication cost due to inter-processor communication increases, but processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware section 120 in advance in anticipation of the extension function section 131 to be added, but it may be necessary to prevent modification of the device-dependent API 23 or other device-independent application sections 130. They may be added or deleted accordingly.

In this example, the software area is the basic function section 132, the management/control agent section 133, the extended function section 131, and the middleware section 120, but the software area includes service adaptation (encryption, fragment processing, GEM Framing/XGEM framing, PHY adaptation FEC, scrambling, synchronization block generation/extraction, GTC (GPON Transmission Convergence) framing, PHY framing, SP conversion, and encoding methods may also be targeted.Architecture softening functions An implementation example and an example of functional arrangement corresponding to the hardware section will be described.The functional arrangement includes, for example, providing a software function in a network device or an external server.This is the same in other examples.

(Second example of architecture)
FIG. 3 is a diagram illustrating a second example of the architecture of a communication device. In FIG. 3, the communication device is configured to further include a device-dependent application section 150 under the middleware section 120 of the communication device shown in FIG. The second example of the architecture is the same as the first example of the architecture except that it includes the device-dependent application section 150.

In FIG. 3, the communication device includes a hardware section 111 (PHY) and a hardware section 112 (MAC) that depend on the standard of the device-dependent section 110 or the device manufacturing vendor, and a hardware section 111 (PHY) and a A software section 113 that executes a driver, firmware, etc. that drives the hardware section 112 (MAC), and at least a part of the hardware section 111 (PHY) and the hardware section 112 (MAC) of the device dependent section 110 and the software section 113. The device-dependent application section 150 to be driven, the middleware section 120 that hides the differences between the hardware section 111 (PHY), hardware section 112 (MAC), software section 113, and device-dependent application section 150 of the device-dependent section 110, and the device-dependent application section 150. The device includes a general-purpose device-independent application section 130 that does not depend on the device.

The middleware section 120 and the device-dependent application section 150 are connected through a device-dependent API 23. The device-dependent application section 150 and the OAM section 114, software section 113, hardware section 111 (PHY), and hardware section 112 (MAC) of the device-dependent section 110 are connected through a device-dependent API 24. The device-dependent application section 150 and the management/control agent section 133 are connected through an API 26.

The device-independent application section 130 includes, for example, a management/control agent section 133 that receives communication from the EMS 140, a basic function section 132, and an extended function section 131. The device-independent application section 130 does not need to include any one of the management/control agent section 133, the basic function section 132, and the extended function section 131, as in the first example of the architecture. The device-independent application unit 130 may further include functional units other than the management/control agent unit 133, the basic function unit 132, and the extended function unit 131. Further, as in the first example of the architecture, it is preferable that the extended function section 131 can be added, deleted, replaced, or changed without affecting other functions.

The basic function section 132 may be included as a part of each extended function section 131, or may be substituted at a lower level of the middleware section 120. When the extended function section 131 includes the basic function section 132, when a lower part of the middleware section 120 replaces the basic function section 132, or when a combination thereof, the device-independent application section 130 includes the basic function section 132. You don't have to.

Further, a part of the basic function section 132 may also be replaced by the device-dependent application section 150 that is lower than the middleware section 120. The management/control agent unit 133 does not need to input/output information to/from the EMS 140 when automatically setting according to predetermined settings. Furthermore, if the management/control agent unit 133 does not have a management setting function, and the other device-independent application unit 130, basic function unit 132, or device-dependent unit 110 has a management setting function, the device-independent application unit 130 The management/control agent section 133 may not be provided.

Direct input/output may be performed between the EMS 140 and the device-independent application section 130. When the lower part of the middleware section 120 completely replaces the basic function section 132, the device-independent application section 130 does not need to include the basic function section 132.

In the communication device shown in FIG. 3, the device-dependent application section 150 may input/output information via the middleware section 120, may input/output information directly from the management/control agent section 133, or may input/output information directly from the management/control agent section 133. Information may be input/output to/from any one of them, or may be input/output directly to/from the EMS 140. Further, if the device-dependent application section 150 is automatically configured according to predetermined settings without receiving communication from the EMS 140 and can acquire management and control information from the EMS 140 via the middleware section 120, the device The independent application section 130 does not need to include the management/control agent section 133.

The device-independent application section 130 inputs information between at least the hardware section 111 (PHY) and the hardware section 112 (MAC) of the device-dependent section 110 or the software section 113 via the middleware section 120. Output. The device-independent application section 130 inputs and outputs data to and from each other via the middleware section 120 as necessary. In particular, when the device-independent application section 130 executes control or management according to information input/output with the EMS 140, the device-independent application section 130 exchanges information with the management/control agent section 133 that receives communication from the EMS 140. Input/output.

The NE management/control unit 115 inputs/outputs NE management information and control information to/from the management/control agent unit 133 via the middleware unit 120. The NE management/control unit 115 may directly input/output NE management information and control information to/from the EMS 140 without going through the middleware unit 120 .

The device-dependent application unit 150 inputs and outputs NE management information and control information to and from the management/control agent unit 133. The device-dependent application section 150 may directly input/output information to/from the EMS 140 without going through the management/control agent section 133 . The management/control agent section 133 inputs and outputs information between the EMS 140, the middleware section 120, and the device-dependent application section 150. The middleware section 120 inputs and outputs NE management information and control information to and from the NE management/control section 115.

The NE management/control unit 115 may directly input/output NE management information and control information to/from the EMS 140 without going through the middleware unit 120 . The middleware section 120 inputs and outputs information to and from the device-independent application section 130 via the device-independent API 21, and the OAM section 114, driver, firmware, hardware section 111 (PHY) and Information is input and output to and from the hardware unit 112 (MAC) via the device-dependent API 23.

Similar to the middleware section 120 shown in FIG. 2, the middleware section 120 shown in FIG. 3 receives input as is or in a predetermined format. It is desirable to prepare the device-independent API 21 in the middleware section 120 in advance in anticipation of the extended function section 131 that will be added later. However, if necessary, the device-independent API 23 and other device-independent application sections 130 can be modified. It may be added or deleted in a suppressed manner.

(Third example of architecture)
FIG. 4 is a diagram illustrating a third example of the architecture of a communication device. In FIG. 4, instead of the middleware section 120 described in the first example of the architecture shown in FIG. Performs input/output with. The other device-independent application unit 130 is the same as the first example of architecture.

Note that in the figure, the EMS 140 and the external device 160 are connected to the device-independent application section 130 via the basic function section 132; It is not necessary to connect to section 130. The EMS 140 and the external device 160 may be appropriately connected to the middleware section 120 as necessary, or may be directly connected to the device-independent application section 130. Furthermore, although the expression "connection via the middleware section 120" is used, this expression is expressed from the viewpoint of the device-independent application section 130. In reality, device-independent applications are connected to each other via the middleware unit 120 after connection by hardware.

Compared to the first example of the architecture, the third example of the architecture allows the middleware section 120 including the device-dependent APIs 23 and 25 to be configured for each device that conforms to a different standard, generation, method, system, device type, or manufacturing vendor. There is no need to create one. As a result, the communication device of the third example of the architecture has the effect that more functions can be generalized and ported between generations of devices, connectivity can be easily verified, and the functions of the devices can be made more robust.

The communication device according to the third example of architecture includes a device dependent section 110 and a device independent application section 130. The device-dependent unit 110 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC) that depend on a standard to comply with or a device manufacturing vendor. A software section 113 such as a driver, firmware, etc. that drives the . Drivers and the like hide differences in the device-dependent section 110.

The device-independent application section 130 includes an extended function section 131 and a basic function section 132. The basic function section 132 uses a device-independent API 27 (porting IF) to connect the device to the device via a driver that hides the difference between the hardware section 111 (PHY), the hardware section 112 (MAC), and the device-dependent software section 113. It is connected to the dependent unit 110. The device-independent application section 130 connects the hardware section 111 (PHY) and the hardware section 112 (MAC) via a driver that hides the difference between the device-dependent software section 113 and the hardware section 111 (PHY) and the hardware section 112 (MAC). Data is input/output between the software section 112 (MAC) and the device-dependent software section 113.

The basic function section 132 and the extended function section 131 are connected via a device-independent API 22 (extension IF). The basic function section 132 and the device dependent section 110 are connected via a device independent API 27. The basic function unit 132 of the device-independent application unit 130 inputs information between the hardware unit 111 (PHY) and the hardware unit 112 (MAC) and the extended function unit 131 instead of the middleware unit 120. Perform output.

The device-independent application section 130 inputs and outputs each other via the basic function section 132 as necessary. The extended function section 131 of the device-independent application section 130 inputs and outputs information via the basic function section 132 and the device-independent API 22. The basic function unit 132 inputs and outputs information via the extended function unit 131 and the device-independent API 22, and controls the OAM unit, driver, firmware, hardware unit 111 (PHY), and hardware unit 112 (MAC) of the device-dependent unit 110. ) and the device-independent API 27.

Similar to the middleware section 120 shown in FIG. 2, the basic function section 132 receives information as is or in a predetermined format. For example, if it is another device-independent application section 130, the basic function section 132 converts the input format into the device-independent API 22 format, and converts it into the device-dependent OAM section, driver, firmware, and hardware section. If so, input the information after converting it into the device-independent API 22 format of the input format, or after terminating and performing predetermined processing. During input, the basic function unit 132 deletes unnecessary input information from each input destination, and if there is missing information, collects and supplements it via other device-independent APIs 22 and device-independent APIs 27. This is desirable. However, the basic function unit 132 may broadcast or multicast the input to the input destination to simultaneously notify related applications and the like.

The device-independent application section 130 includes, for example, extended function sections 131-1 to 131-3 and a basic function section 132. The device-independent application section 130 does not need to include either the extended function section 131 or the basic function section 132. The device-independent application unit 130 may further include functional units other than the extended function unit 131 and the basic function unit 132. For example, if the extended function section 131 is not required, the device-independent application section 130 does not need to include the extended function section 131.

It is preferable that the extended function section 131 can be added or deleted independently without affecting other functions. For example, if the extended function section 131 is used for multicast service or power saving in accordance with service requirements, the extended function section 131 is added as appropriate when it becomes necessary, and deleted as appropriate when it is no longer needed. However, they may be replaced or changed according to changes.

It is desirable that the device-independent API 22 is provided in the basic function section 132 in advance in anticipation of the extended function section 131 that will be added later. Additions or deletions may be made in a manner that suppresses modification of the dependent application section 130.

(Fourth example of architecture)
FIG. 5 is a diagram illustrating a fourth example of the architecture of a communication device. The difference between the fourth example of architecture and the third example of architecture is that the communication device includes a device-dependent application section 150 under the basic function section 132. In this way, the communication device according to the fourth example of the architecture has the effect of simplifying the configuration of the basic function section 132 by including the device-dependent application section 150.

The communication device shown in FIG. 5 includes a device dependent section 110 and a device independent application section 130. The device-dependent unit 110 includes a hardware unit 111 (PHY) and a hardware unit 112 (MAC) that depend on the standard that complies with or the equipment manufacturing vendor. It has a software section 113 such as a driver and firmware to drive, and a device-dependent application section 150 that drives at least a part of the device-dependent section 110. The device-independent application section 130 communicates between the porting IF and the device-dependent application via a driver that hides the difference between the porting IF, the hardware section 111 (PHY) and the hardware section 112 (MAC), and the device-dependent software. This is a general-purpose device-independent application that executes device-independent processing via the unit 150. The basic function section 132 in the device-independent application section 130 and the device-dependent application section 150 in the device-dependent section 110 are connected via the device-independent API 27. The device dependent application section 150 and other functional sections of the device dependent section 110 are connected via the device dependent API 24.

The basic function section 132 in the device-independent application section 130 performs input/output with hardware and the extended function section 131 instead of the middleware section 120. The basic function unit 132 may include a management/control agent unit 133 (see FIGS. 2 and 3) that receives communications from the EMS 140, or the management/control agent unit 133 may be included as the extended function unit 131. It's okay.

The basic function section 132 inputs and outputs input and output from the extension function section 131 and the device-independent API 22 (extension IF), and the OAM section, driver, firmware, hardware section 111 (PHY), and hardware section of the device-dependent section 110. 112 (MAC), and the driver of the device-dependent section 110 that hides the difference between the device-independent API 22 (porting IF) and the device-dependent section 110, or the device-dependent application section 150 and the device-independent API 27. .

Similar to the middleware section 120 shown in FIG. 2, the basic function section 132 receives input as is or in a predetermined format. Similar to the third example of the architecture, the basic function section 132 may include a management/control agent section 133 that receives communication from the EMS 140, or the management/control agent section 133 may be included as an extended function section 131. You may prepare.

The device-independent application section 130 includes, for example, extended function sections 131-1 to 131-3 and a basic function section 132. The device-independent application section 130 does not need to include either the extended function section 131 or the basic function section 132, as in the third example of the architecture. The device-independent application section 130 may further include functional sections other than the extended functional section 131 and the basic functional section 132, as in the third example of the architecture.

As with the third example of the architecture, it is preferable that the extended function section 131 can be added, deleted, replaced, or changed independently from each other without affecting other functions. A part of the basic function section 132 may be replaced by a device-dependent application section 150. Although the device-dependent application section 150 directly inputs and outputs information from the basic function section 132, it is also possible to input and output information to and from the EMS 140 without going through the basic function section 132, either as is or after a predetermined conversion. good.

As with the first example of the architecture shown in FIG. , the device-independent API 27, other device-independent application section 130, device-dependent application section 150, or device-dependent API 24 may be added or deleted as necessary in a manner that suppresses modification.

(Fifth example of architecture)
The upper right diagram in FIG. 6 is a diagram showing a fifth example of the architecture. The lower right diagram in FIG. 6 corresponds to the first to fourth examples of architecture. The figure shows a case where the communication device is an OLT. The fifth example of architecture is a functional cloud that utilizes existing/off-the-shelf OLT hardware to add/change functions depending on the service by implementing OLT functions on external hardware (cloudification). This method is suitable for taking a structuring approach.

In this example, the communication device consists of existing/off-the-shelf hardware and external hardware. For example, existing/commercially available hardware is a non-general-purpose device-dependent part 110 that depends on the device, a middleware part 121 that hides differences in hardware and software on external hardware, and a general-purpose device whose operation does not depend on the device. and a device-independent application section 130. Therefore, the device-dependent section (vendor-dependent section) below the middleware shown in the figure is a functional section that depends on the standard to which the device of the communication device complies and the manufacturer of the device. Further, the device-independent application unit 130 is a functional unit that does not depend on the standard to which the device of the communication device complies or the manufacturer of the device.

The middleware section 121 and the device-independent application section 130 are connected via a device-independent API, which is a device-independent input/output IF. For example, the software section, OAM, hardware section (PHY), and hardware section (MAC) of the device dependent section 110 and the middleware section 121 on external hardware are device dependent, which is an input/output IF that depends on the device. Connections are made via APIs and device-to-device connections between existing/off-the-shelf hardware and external hardware.

This architecture allows the device-independent application section 130 to easily and flexibly add extended function sections (original function sections), thereby making it possible to provide communication services in a timely manner. Here, the device dependent unit 110 may be maintenance and operation, access control, physical layer processing, or optical module shown in FIG. 6, depending on the configuration of the device itself.

For example, functions that are updated frequently, such as priority processing of main signals and DBA that improves line usage efficiency, or functions that contribute to communication service differentiation are prioritized and set as the device-dependent section 110 or the device-independent application section 130. You can decide. Furthermore, the device-independent application section 130 may be selected from devices that have a small difference in at least one of the standards, generations, methods, systems, device types, and manufacturing vendors that the devices to be shared are compliant with.

Any feature of a compliant standard, generation, method, system, device type, or manufacturing vendor, even if it is not optimal for the compliant standard, generation, method, system, device type, or manufacturing vendor. In order to generalize the functions, a common IF may be used to perform the functions. The common IF may include IFs and parameters that are not used in any of the standards, generations, systems, systems, device types, and manufacturing vendors that the device-dependent unit 110 complies with.

A conversion function unit that converts IF, parameters, etc. to correspond to the device-dependent unit 110 in at least one of the middleware unit 121, the driver of the device-dependent unit 110, and the device-dependent application unit 150 (vendor-dependent application unit). Alternatively, a functional unit may be further provided that automatically sets the missing IF, parameters, etc.

The device dependent section 110 includes a hardware section and a software section. The software section executes device-dependent drivers, firmware, applications, etc.

The device-dependent unit 110 may not include a PMD that connects to a physical medium, a MAC, a PMA that serializes data, and a part of the PCS or PHY that encodes data. For example, only optical-related functions may be provided without low-level signal processing such as modulation/demodulation signal processing, forward error correction (FEC), code/decoding processing, and encryption processing.

The device-independent application section 130 includes, for example, a management/control agent section 133 that acquires data from the EMS, extended function sections 131-1 to 131-3, and a basic function section 132. Hereinafter, items common to the extended function sections 131-1 to 131-3 will be referred to as "extended function section 131" with part of the reference numerals omitted. An EMS is, for example, a controller that controls network elements. Note that the device-independent application section 130 does not need to include any one of the management/control agent section 133, the extended function section 131, and the basic function section 132.

The device-independent application section 130 may further include components other than the management/control agent section 133, the extended function section 131, and the basic function section 132. For example, if the extended function section 131 is not required, the device-independent application section 130 may not include the extended function section 131. Further, the device-independent application section 130 may include one or more extended function sections 131.

It is preferable that the extended function section 131 can be independently added, deleted, replaced, or changed without having unnecessary effects on other functions. For example, the extended function unit 131 may be added, deleted, replaced, or changed as appropriate when the extended function unit 131 is required to perform multicast service or power saving support in accordance with service requirements. .

The basic function section 132 may be included in the device-independent application section 130 as part of the extended function section 131, or may be replaced by a function section lower than the middleware section 121. When the extended function section 131 includes the basic function section 132, the device-independent application section 130 does not need to include the basic function section 132. When a functional unit lower than the middleware unit 121 replaces the basic functional unit 132, the device-independent application unit 130 does not need to include the basic functional unit 132. If the extended function section 131 includes the basic function section 132 and a function section lower than the middleware section 120 replaces the basic function section 132, the device-independent application section 130 does not need to include the basic function section 132.

The management/control agent unit 133 does not need to input/output to/from the EMS 140 when performing automatic settings according to predetermined settings without receiving communication from the EMS 140 . Furthermore, if the management/control agent section 133 does not have a management setting function and the other device-independent application section 130, basic function section 132, or device-dependent section 110 has a management setting function, the device-independent application section 130 The management/control agent section 133 may not be provided.

The EMS 140 and the device-independent application unit 130 may directly input and output information. Further, the device dependent unit 110 does not need to include the NE management/control unit 115 and the IF of the NE management/control unit 115.

The basic function section 132 may be included in the device-independent application section 130 as part of the extended function section 131, or may be replaced by a lower function section of the middleware section 120. When the extended function section 131 includes the basic function section 132, when a lower function section of the middleware section 120 replaces the basic function section 132, or when a combination thereof, the device-independent application section 130 is a basic function section. 132 may not be included. Further, a part of the basic function section 132 may be replaced by a device-dependent application section 150 that is a lower function section of the middleware section 120.

The management/control agent unit 133 does not need to input/output information to/from the EMS 140 when automatically setting according to predetermined settings. Furthermore, if the management/control agent unit 133 does not have a management setting function and other device-independent application units 130, basic function unit 132, or device-dependent unit 110 have management setting functions, the device-independent application unit 130 does not have the management setting function. - The control agent unit 133 may not be provided. The EMS 140 and the device-independent application unit 130 may directly input and output information.

An example of input/output between the device-independent application section 130 and the device-dependent section 110 is as follows. For example, the DBA application section and the protection application section mutually input and output information with the embedded OAM engine of the TC layer. The DWBA application and ONU registration authentication application unit input and output information to and from the PLOAM engine of the TC layer. The power saving application unit inputs and outputs information to and from the OMCI and the L2 main signal processing function unit (L2 function unit). The MLD proxy application section inputs and outputs information to and from the L2 function section. The low speed monitoring application (OMCI) inputs and outputs information to and from OMCI. The OMCI and L2 functions operate the XGEM framer and encryption. Here, DWBA and DBA may be separate, integrated, or combined. For example, the management/control agent unit 133 is an application unit for maintenance and operation functions, and inputs/outputs information to/from the EMS 140, which is an NE controller or the like for the NE management/control unit 115.

The device-independent application unit 130 determines the device vendor, system, device type, and device generation, such as ITU-T G. TWDM-PON compliant with 989 series and ITU-T G.989 series. XG-PON compliant with 987 series and ITU-T G. G-PON compliant with 984 series and ITU-T G.984 series. This is an application that operates independently of any 983 series compliant BPON. The device-independent application unit 130 detects differences between device vendors, systems, device types, and device generations, such as 10GE-PON compliant with IEEE802.3av and IEEE1904.1, and GE-PON compliant with IEEE802.3ah. This is an app that works regardless of the situation.

Applications of the extended function unit 131 include applications for driving functions for some vendors, methods, types, and generations through the device-independent API 21, and applications for devices of some vendors, methods, types, and generations. It may also include an app that drives the functionality provided for.

The management/control agent section 133 inputs/outputs the EMS 140 and the middleware section 120 . The middleware section 120 inputs and outputs NE management information and control information to and from the NE management/control section 115. The NE management/control unit 115 may directly send/receive NE management information and control information to/from the EMS 140 without going through the middleware unit 120, or may send/receive NE management information and control information via the management/control agent unit 133. It may be sent and received.

The middleware section 120 inputs and outputs information via the device-independent application section 130 and device-independent API 21. The middleware section 120 inputs and outputs information to and from the OAM section 114, driver, firmware, hardware section 111 (PHY), or hardware section 112 (MAC) of the device dependent section 110 via the device dependent API 23. The middleware unit 120 outputs the input information as is or in a predetermined format. For example, if the output destination is each section of the device-independent application section 130, the middleware section 120 converts the information into the input format of each section of the device-independent API 21. If the output destination is the OAM unit 114, driver, firmware, hardware unit 111 (PHY), or hardware unit 112 (MAC) of the device dependent unit 110, the middleware unit 120 outputs the device dependent API 23 in the format input to each. The information is sent to the output destination after being converted into a format or after being terminated and subjected to predetermined processing.

During input, the middleware unit 120 deletes unnecessary input information for each input destination, and if there is insufficient information, it can collect and supplement it via other device-independent APIs 21 and device-dependent APIs 23. desirable. Further, when inputting to the middleware unit 120, the information may be broadcast or multicast to be simultaneously notified to related applications and the like.

Although the middleware section 120 and the device-dependent section 110 are illustrated as a single unit, each may be composed of a plurality of units. When the hardware of the device-dependent unit 110 includes a plurality of processors, the middleware unit 120 may perform input/output across processors and hardware using inter-processor communication or the like. The device-independent application section 130 or the device-independent application section 130 may be placed in the user space on a single processor as an execution program such as a DLL, or in the user space on multiple processors. You may.

Furthermore, the device-independent application section 130 may be placed in the kernel space after securing an input/output IF such as an API, or may be placed together with the middleware section 120 that has an IF that can be independently replaced with firmware, etc. Alternatively, it may be incorporated into firmware or the like and recompiled. Any combination of user space and kernel space may be used for each device-independent application unit 130.

The device-independent application unit 130 corresponding to the same function may be implemented in both user space and kernel space. In this case, for example, one may be selected by switching, both may be processed in cooperation, or only one may perform actual processing. The same applies to the software of the device dependent unit 110.

Preferably, the more high-speed processing is required, such as main signal processing, DBA processing, and low-layer signal processing, the more high-speed processing is expected with less overhead, although there is a trade-off with scalability and immediacy of replacement. It is desirable to incorporate it into the kernel space or firmware. The processor in which the device-dependent application section 150 is placed is also in the user space of the processor that performs the actual processing or the processor in its vicinity, from the viewpoint of restrictions on bus and speed due to inter-processor communication, and influence on other programs due to occupancy of the communication path. It is desirable to place it in the kernel space or firmware. However, in order to reduce the capacity of a processor that performs actual processing or a processor in its vicinity, the communication cost due to inter-processor communication increases, but processing may be performed by a remote processor.

It is desirable that the device-independent API 21 is provided in the middleware section 120 in advance in anticipation of the extension function section 131 to be added, but it may be necessary to prevent modification of the device-dependent API 23 or other device-independent application sections 130. They may be added or deleted accordingly.

(6th example of architecture)
The sixth example of the architecture includes a hardware section 111 (PHY) and a hardware section 112 (MAC) that depend on a standard that complies with or a device manufacturing vendor as a device-dependent section 110, and a hardware section 111 (PHY) and a A software section 113 such as a driver/firmware that drives the section 112 (MAC), and a device-dependent application section 150 that drives at least a part of the device-dependent section 110 are provided.

The device dependent application section 150 and the device dependent section 110 are connected via the device dependent API 24. The device-dependent application section 150 may include an equivalent to the management/control agent section 133 that receives communications from the EMS 140. The device-dependent API 24 may be added or deleted as necessary in a manner that suppresses modification of the device-dependent application section 150 and the device-dependent API 24.

Note that the configurations of communication devices shown in the first to sixth examples of communication device architecture are described based on the OLT of a PON that complies with ITU-T recommendations, such as TWDM-PON. It may be an OLT or ONU of a PON that complies with ITU-T recommendations other than TWDM-PON, or it may be a PON that complies with IEEE standards such as GE-PON or 10GE-PON. The layer or PMD layer is the same if read as the corresponding layer.

Below, TWDM-PON includes PON multicast function, power saving control function, frequency/time synchronization function, protection function, maintenance and operation function, L2 main signal processing function, PON access control function, and PON main signal. An example will be explained in which the computer mainly has a processing function. Hereinafter, the PON multicast function, power saving control function, frequency/time synchronization function, protection function, maintenance and operation function, L2 main signal processing function, PON access control function, and PON main signal processing function are as follows. It is called "8 main functions".

FIG. 7 is a diagram showing an example of the configuration of the communication device and the external server 16. The communication system shown in FIG. 7 includes a communication device and an external server 16. The communication device includes at least a portion of a transmitting/receiving section 11 (TRx), a switch section 12 (SW), a switch section 13 (SW), a control section 14, and a proxy section 15. Note that the communication device may include an external server 16.

Although FIG. 7 shows a configuration in which transmitting/receiving units 11 that transmit and receive (communicate) optical signals of different wavelengths (λA to λN) are connected to the same switch unit 12, Embodiment 1-1 is not limited to this. For example, in addition to a configuration in which transmitting and receiving sections 11 that transmit and receive optical signals of different wavelengths (λA to λN) are connected to the same switch section 12, transmitting and receiving sections 11 that transmit and receive optical signals of the same wavelength are connected to the same switch. Alternatively, among the transmitting/receiving units 11 that transmit and receive optical signals of different wavelengths (λA to λN), at least some of the transmitting/receiving units 11 of the wavelengths may be connected to the same switch unit 12. Alternatively, part or all of the transmitting/receiving section 11 may be a transmitting/receiving section 11 that only performs transmission or only reception.

A communication device such as an OLT may include a transmitting/receiving unit 11 to a control unit 14, and may further include an external server 16 in addition to these units. Further, the OSU may be the transmitting/receiving section 11, or may include a switch section 12 (SW) or a switch section 13 (SW) in addition to this.

When the communication device is an OLT, the OLT may include a transmitting/receiving section 11 (TRx), a switching section 12 (SW), a switching section 13 (SW), and a control section 14, or the transmitting/receiving section 11 (TRx), a switch section 12 (SW), a switch section 13 (SW), a control section 14, and an external server 16. The OSU may be configured from the transmitter/receiver 11 (TRx), the transmitter/receiver 11 (TRx), and the switch 12 (SW), or the transmitter/receiver 11 (TRx) and the switch. It may also be configured from a section 13 (SW).

In the communication system configuration (1-1), the switch unit 12 (SW) mainly distributes wavelengths, but also represents aggregation, distribution, duplication, return, transmission, VID (Virtual LAN Identifier), and priority discard. It is also possible to add tags or replace tags. In the communication system configuration (1-2) described later, upstream traffic is mainly aggregated, but distribution, distribution, duplication, loopback, transmission, tagging, or tagging may also be performed. Downlink traffic may also be aggregated, distributed, distributed, duplicated, looped back, transmitted, tagged, or retagged, or at least some combinations may be performed. Which one to use is determined according to the service policy. This also applies to the subsequent communication system configuration.

The switch section 12 (SW) is connected to the switch section 13 (SW). The switch unit 12 (SW) performs autonomous control, or is controlled by other components such as the transmitting/receiving unit 11 (TRx), the switch unit 13 (SW), the control unit 14, the proxy unit 15, or the external server 16, Alternatively, it is controlled by instructions transferred via other components such as the transmitting/receiving section 11 (TRx), the switch section 13 (SW), the control section 14, the proxy section 15, or the external server 16.

Adding, deleting, or replacing tags in the combination, or aggregating, distributing, sorting, duplicating, folding, transmitting, or at least a part of tagging or tagging, or a combination thereof, without changing tags. Perform processing. This also applies to the subsequent communication system configuration.

Note that the switch unit 12 (SW) is not necessarily controlled. There are cases where at least one of the proxy sections 15 is controlled from the transmitting/receiving section 11, and cases where control information is transferred from the transmitting/receiving section 11 to at least one of the proxy sections 15 without being controlled. The transfer source is, for example, the proxy section 15 or the external server 16. Further, the proxy unit 15 from the transmitting/receiving unit 11 may operate autonomously. This also applies to the subsequent communication system configuration.

The switch unit 13 (SW) is connected to the proxy unit 15 directly or via a concentrator SW or the like. The line concentration SW performs at least part of aggregating, distributing, allocating, duplicating, looping back, or transmitting traffic from or to a plurality of OLTs.

These processes are basic processes such as address management, Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, It may be composed of a Scheduler, a Copy, and a traffic monitor. MAC learning, VLAN control, path control, bandwidth control, priority control, delay control, and Copy may not be provided, and equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed.

The main function of the L2 main signal processing function unit 340 is to process 10 Gbit/s/λ and 2.5 Gbit/s/λ for each wavelength, respectively. If the above stream processing processes multiple wavelengths, multiple wavelengths are required.

FIG. 13 is a diagram showing a first example of the functional configuration of the maintenance and operation function section 330. The maintenance and operation functions of the maintenance and operation function unit 330 include device settings (manual, batch, automatic, operation trigger) of ONU, OSU, OLT, or SW, configuration backup, FW update, device control (reset), and redundancy. Has configuration correspondence. These processes may include a basic process CLI-IF, device management IF, operation IF, general-purpose Config-IF (Netconf, SNMP, etc.), and table management. Equivalent processing may be realized by a combination of basic processing without providing device settings, configuration backup, FW update, device control, and redundant configuration support. Moreover, the order may be changed.

The main functions of the maintenance operation function unit 330 are to send an ACK within 100 milliseconds after receiving an instruction, and within 200 milliseconds from receiving an instruction to sending a reflection completion notification (however, configuration backup including data transfer and FW update are It is required to comply with regulations such as depending on the scale (size, number of users). As an example of functional division, processing may be performed by an application except for hardware Config, and software and setting data may be processed by an application on the external server 16 in FIG. 7 without being held in the ONU or OLT. This can also be achieved by unifying commands and defining sequences.

FIG. 14 is a diagram illustrating a second example of the configuration of functions that the maintenance and operation function section 330 has. Processes constituting the functions of the maintenance operation function unit 330 include device status monitoring (CPU/memory/power supply/switching), traffic monitoring, alarm monitoring (ONU abnormality, OLT abnormality), and testing (loopback). These processes may consist of basic processes such as alarm notification, log recording, L3 packet generation/processing, and table management. Equivalent processing for device status monitoring, traffic monitoring, alarm monitoring, and testing may be realized by combining basic processing. Moreover, the order may be changed.

The main functions of the maintenance and operation function unit 330 are required to comply with regulations such as a latency of 100 milliseconds or less. As an example of functional division, only the notification/display IF is an application, and the items that need to be monitored (CPU load, memory usage, power status, power consumption, Ethernet (registered trademark) link status, etc.) are handled by the device-dependent unit 110. However, it is also possible to perform processing by an application that clears the IF, such as reading a notification from the device-dependent unit 110, sending the notification to a network (NW), and writing it to a file.

FIG. 15 is a diagram showing a third example of the functional configuration of the maintenance and operation function section 330. The maintenance and operation function of the maintenance and operation function section 330 includes monitoring and control input/output that requires high speed (sleep instruction/response, λ setting switching instruction/response, etc.). As means for this processing, a physical layer OAM (PLOAM) message and a bit indication (embedded OAM) in the header are used. These processes may include basic processing such as PLOAM processing, embedded OAM processing, communication with the power saving control function section 360, communication with the protection function section 380, and communication with the PON access control function section 320. For monitoring and control input/output that requires high speed, equivalent processing may be realized by combining basic processing. Moreover, the order may be changed. The main functions of the maintenance and operation function unit 330 are required to comply with regulations such as keeping PLOAM processing within 750 microseconds.

FIG. 16 is a diagram showing an example of the functional configuration of the PON multicast function section 350. Processes constituting the PON multicast function of the PON multicast function unit 350 include multicast stream identification or distribution, MLD proxy/snooping, ONU filter settings, and inter-wavelength setting migration. These processes may consist of basic processes such as L2 identification and distribution, L3 packet processing (preferably including IPv6 Parse), L3 packet generation, table management, and communication with the OMCI function. Equivalent processing for multicast stream identification or distribution, MLD proxy/snooping, ONU filter setting, and inter-wavelength setting migration may be realized by a combination of basic processing. Moreover, the order may be changed.

Although MLD is used as an example of a multicast protocol in this application, the same applies to other protocols such as IGMP.

In the main function of the PON multicast function unit 350, when processing identification/distribution of 10 Gbit/s/λ and 2.5 Gbit/s/λ for each wavelength, 10 Gbit/s/λ and 2.5 Gbit/s, respectively. /λ or more, if multiple wavelengths are to be processed, multiple wavelengths are required. Further, in the main function of the PON multicast function unit 350, the zapping performance (JOIN latency) for packet processing is required to comply with regulations such as an average of 1.5 seconds or less.

As an example of functional division, identification and distribution of multicast (MC) streams can be handled by software if it is a CPU with high-speed processing capability, but it is preferable to use hardware + config. In addition, the application system and ONU settings for uplink are processed by the application because the frequency and delay constraints are loose.

FIG. 17 is a diagram showing an example of the functional configuration of the power saving control function section 360. Processes constituting the functions of the power saving control function unit 360 include sleep proxy/traffic monitor, ONU wavelength setting, and inter-wavelength setting migration. These processes consist of basic L3 packet processing (preferably with IPv6 Parse), L3 packet generation, table management, OSU power saving state diagram (SD), and communication with the OMCI function. good. Equivalent processing for sleep proxy/traffic monitor, ONU wavelength setting, and inter-wavelength setting migration may be realized by a combination of basic processing. Moreover, the order may be changed.

This main function requires compliance with regulations such as transmitting/receiving rise time (receiver/transmitter) of 10 ms/5 ms and rise time (LC/OSU/OLT) of 100 ms/1 s/10 s. It will be done.

As an example of division of functions, a power save (PS) application or proxy processing depending on the signal may also be processed by the application. Power-saving control state transition management (driver section) requires speed, but it can also be processed by an app. In the traffic monitor, only the config can be processed by an application.

FIG. 18 is a diagram illustrating an example of the functional configuration of the frequency/time synchronization function section 370. The OLT slave-synchronizes its own real-time clock (RTC) with the host device using SyncE (Synchronous Ethernet (registered trademark)) (for frequency synchronization) and IEEE 1588v2 (time synchronization). Furthermore, using OMCI, the ONU is notified of the correspondence between the PON's superframe counter (SFC) and absolute time of day (ToD) information. These processes may consist of basic processing such as holding a real-time clock. Equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed.

This main function has frequency synchronization accuracy of +/-50 ppb (LTE FDD, same TDD), time synchronization accuracy +/-1 to 1.5 microseconds (LTE TDD, small cell), +/-1 microsecond (G. 987.3) and other regulations. As an example of division of functions, the real-time clock itself may be handled by the device-dependent unit 110, and the time adjustment calculation for the host device may be processed by an application (depending on accuracy, it may also be handled by the device-dependent unit 110).

FIG. 19 is a diagram showing an example of the functional configuration of the protection function section 380. The protection function section 380 includes redundancy switching (CT, SW, NNI, CONT, PON (Type A, B, C)) as a process constituting the protection function. These processes may include basic processes such as redundant path setting, switching trigger detection, switching notification transmission/reception, and switching processing. Equivalent processing may be realized by a combination of basic processing. Moreover, the order may be changed.

In this main function, forced switching is required to comply with regulations such as 50 milliseconds or less. As an example of division of functions, processing may be performed by an application, except for hardware switching trigger detection and switching processing such as failure detection. If a redundant path is not set in advance and an instruction is given to (or from) the EMS side when a switching trigger is detected, it depends on the device.

Note that the eight main functions may be provided as needed; for example, it may be provided with only the PON main signal processing function, PON access control function, L2 main signal processing function, and maintenance operation function, or it may be provided with other functions. It's okay. Furthermore, the evaluation of whether or not each function can be converted into software is an example based on the assumption that the processing capacity of the OLT is expected in 2018 and that the application of soft switches is not assumed. It may be changed as appropriate based on the assumed processing capacity and application of the soft switch. Even if a function can be made into software, it is not necessary to make it into software. The internal configuration of each function may be any other configuration as long as the same function can be achieved.

The main areas of softening are the algorithms included in the eight main functions. The functions set as the software area are the device-independent application section 130 on the device-independent APIs 21 and 22. For example, algorithms for ONU registration or authentication functions, DWBA functions, setting/management/monitoring control functions, and power saving control functions that contribute to differentiated services are handled as the extended function unit 131 in the device-independent application unit 130. The MLD proxy app includes multicast functionality.

The extended function section 131 is selected depending on the importance of the application, such as the update frequency of functions and the implementation of unique specifications. Items that are updated less frequently or have lower requirements for realizing unique specifications are the middleware section 120 other than the basic function section 132 and the device-independent application section 130, device-dependent software, the hardware section 111 (PHY), and the hardware section 112 ( MAC) is preferable. In particular, it is preferable that functions that are limited by software processing capabilities remain in the hardware unit 111 (PHY) and hardware unit 112 (MAC). For example, functions that are frequently updated or contribute to service differentiation, such as priority processing of main signals and DBA that improves line utilization efficiency, and management that is closely related to the operator's work flow and requires unique specifications for each operator. The control function is referred to as the extended function section 131.

FIG. 20 is a diagram illustrating a detailed example of the architecture of a communication device. The embedded OAM engine 114a (Embedded OAM Engine) is connected to the DBA application section and the protection application section via the middleware section 120. The PLOAM engine 114b is connected to the DWBA application, ONU registration authentication, high-speed monitoring application, power saving application, and protection application via the middleware section 120.

OMCI is connected to the power saving application and low speed monitoring application (OMCI) via the middleware section 120. The L2 function is connected to the power saving application and the MLD proxy application via the middleware section 120. The L2 function section is further connected to a setting/management application via the middleware section 120. The NE management unit 115a is connected to a settings/management application. The NE control 115b is connected to a low speed monitoring application (EMS-IF).

FIG. 21 is a diagram showing the flow of signals/information between functional units within a communication device. The figure shows the flow of signals/information between functional units within the communication device, focusing on the In/Out of the OLT. As shown in the figure, the OLT as a communication device is composed of an API lower processing entity (FASA platform) and an application (FASA application).

The API lower processing entity is an MPCP/DBA processing entity whose OLT input/output targets are transmission instructions and reception notifications for MPCP transmission/reception, an OAM processing entity whose OLT input/output targets are OAM transmission/reception, and an OLT input/output target is ONU authentication transmission/reception. A certain ONU authentication processing entity, an MLD/IGMP processing entity whose OLT input/output target is MLD/IGMP transmission/reception, another protocol processing entity whose OLT input/output target is transmission/reception of other protocols, OLT input/output is main signal processing such as bridge/encryption, etc. The example is a main signal setting processing entity that performs settings, references, and state acquisition, and a device management processing entity whose OLT input/output targets are OLT hardware, IF, OS, etc. Here, it is assumed that the transmission instruction and reception notification for MPCP transmission/reception are directly directed to the driver, and are preferably something like send_frame(*raw_frame);.
In the figure, examples of applications include DBA, ONU management, line management, multicast, EtherOAM, redundancy, device management, alarm management, Netconf agent, and application management.

In/Out of the OLT is roughly divided into three types: input/output to the ONU, setting/notification to the OLT itself, and input/output to the EMS. From the perspective of an application on the upper side of the API, compared to processing such as hitting the driver directly, the processing for the lower side of the API is (a) easy (convenient), and (b) common (across multiple types). , (c) It is desirable that there be a processing entity that conveniently processes the information.

The functional division of the API lower processing entity is illustrated below. The app has a corresponding process. The functional division between the API lower processing entity and the application may be any of the following or may be different depending on the actual processing situation.

(0) Message through: A message is passed between the upper side of the API and the ONU/upper NW.

(1) Framing: A message is deframed, decomposed or processed into elements as necessary, and provided to the upper side of the API. The upper part of the API passes information to the lower part of the API. The API lower processing entity performs the framing. Since the API is highly dependent on each protocol, it may be included in the device-dependent application section. Fixed parameters (type values, etc.) are preferably set from the top of the API at the time of initialization, etc., and retained. Configuration parameters are returned in response to references from the top of the API.

(2) Automatic response: A processing entity is responsible for sending and receiving messages that do not require judgment, such as periodic transmission and fixed responses. It is desirable that the operation settings be made in advance from the top of the API. For example, response period. Notify the results only when notification to the upper API is necessary.

(3) Autonomous judgment: Processing that involves judgment is also handled by the processing entity. Policy settings are made in advance from the top of the API.

Although this figure is described in accordance with IEEE-compliant 10GEPON, the corresponding functions and processes are similar even for devices compliant with ITU-T or other standards. Furthermore, the functions and actual processing conditions are merely examples, and may be added, deleted, replaced, or changed as appropriate depending on the conditions.

FIG. 22 is a diagram illustrating an example of an application executed by a communication device. CPU processing is classified into three groups. The three groups are CPUs for Cont, CPUs for OSU, and CPUs for SW. The CPU processing for Cont is processing for executing a low-speed monitoring application (OMCI), a low-speed monitoring application (EMS-IF), and a setting/management application. The processing of the CPU suitable for SW is the processing of executing the MLD proxy application. The CPU processing for OSU is processing for executing a power saving application, a protection application, a high speed monitoring application, a DBA application, a DWBA application, and an ONU registration authentication application. The device setting IF may be part of the EMS-IF, or may be equivalent to the device dependent API 25.

This is an example in which each application is processed by the CPU on the CPU package. In FIG. 22, each application is oriented toward a control package (Cont. in FIG. 22) which is a control unit in the OLT, toward an OSU package (OSU in FIG. 22) including a plurality of optical transceivers (λCard in FIG. 22), and toward OSU and They are classified into three groups suitable for SW packages that perform data input/output with devices on the upper network side. The OSU group is used as a power saving application, protection application, high-speed monitoring application, DBA application, DWBA application, ONU registration authentication application, the SW group is used as an MLD proxy application, and the Cont group is used as a low-speed monitoring application (OMCI) and a low-speed monitoring application (EMS- IF), and a settings management app. Further, although centralized control by the CPU is assumed, the applications of each classified group may be distributed and arranged in respective packages (Cont, OSU, SW). In addition, it may be arranged on any one of Cont, OSU, and SW, or a combination of a plurality of them, without depending on the above classification. Further, the device setting IF in FIG. 22 may be a part of the EMS-IF, or may be equivalent to the device-dependent API 25 in FIG. Further, although the processing of the application is performed on the CPU, part or all of it may be processed on an alternative device having a processing function, such as a processor other than the CPU such as a GPU, NPU, or DSP, or an FPGA. The same applies to other embodiments.

FIG. 23 is an example in which an application is placed on a server or the like instead of a CPU package. The application is processed on a server or the like, and the processing results of the application arrive at the OLT after being transmitted over the transmission path in a format that can be transmitted over the transmission path, such as an Ethernet (registered trademark) frame. Here, the format that can be transmitted over the transmission path may be a frame other than the Ethernet (registered trademark) frame, TDM, or the like. In addition, the processing results are transmitted via a converter (Conv. in Figure 23), but if the OSU, SW, or λ card can receive the processing results of the application without going through the converter, the conversion No machine is required. The server or the like may be equivalent to the external server 16 in FIG. 7 or may be equivalent to the proxy section 15.

FIG. 24 is a diagram illustrating an example of the functions (processing) of the CPU, the switch unit (SW), and the OSU. The CPU executes a power saving control function and a protection function using an application. The CPU further has a maintenance operation function (Fault Management), a maintenance operation function (GTC/PMD config), a PON access processing function (ONU activation), a PON access processing function (DBA), and a PON access processing function (λ (allocation change), maintenance and operation functions (Service Management), and maintenance and operation functions (Equipment Management). Furthermore, the CPU executes a maintenance operation function (Fault Performance Management) and a multicast function (MLD) using an application.

The switch (SW) has L2 signal processing function (VLAN), L2 signal processing function (QoS, Quality of Service), L2 signal processing function (Mux/DMux, XC, Cross Connect), and multicast function (Copy). is executed by the app. The OSU MAC executes a PON main signal processing function (Security), a PON main signal processing function (Framing), a PON main signal processing function (FEC), and a frequency/time synchronization function using an application.

In FIG. 24, the CPU box shows an example of processing performed by the basic function unit 132 and its own functions, and the OSU MAC shows processing performed by a vendor-dependent part, but the classification is not limited to this. The CPU shown in FIG. 25 may be the CPU package shown in FIG. 23, the server shown in FIG. 23, or another location having processing capability, or a combination thereof. Although the OSU MAC is assumed to be an LSI dedicated to OSU processing, a general-purpose LSI may be used if equivalent processing is possible.

FIG. 25 shows the application processing of the main eight functions and the G. 3 is a diagram showing an example of correspondence with G.989.3 functions; FIG. The DBA application, DWBA application, ONU registration authentication application, power saving application, protection, and high-speed monitoring application are connected to TWDM TC functions of the TWDM TC layer. The MLD proxy is connected to an L2 function. The L2 function unit is connected to a user data client. The setting/management application, the low speed monitoring application (OMCI), and the low speed monitoring application (OSS-IF) are connected to the L2 function. The settings/management application, the low speed monitoring application (OMCI), and the low speed monitoring application (OSS-IF) are further connected to the OMCI client.

FIG. 26 is a diagram illustrating an example of a configuration for acquiring PLOAM and OMCI via SW. That is, FIG. 26 shows a process in which PLOAM and OMCI acquire corresponding data from the control unit 14, proxy unit 15, or external server 16 in FIG. 7 via SW in addition to user data.

A user data client acquires data from a user data adapter via a switch unit (SW). The user data client sends data to the user data adapter via the switch section. The OMCI client of the CPU acquires data from the OMCI adapter via the switch unit. The OMCI client sends data to the OMCI adapter via the switch unit.

The PLOAM processor of the CPU obtains data from the "AMCC PHY adaptation and framing section" via the switch section. The PLOAM processor of the CPU transmits data to the "AMCC PHY adaptation/framing section" via the switch section. Further, the PLOAM processor of the CPU obtains data from the PLOAM partition via the switch. The PLOAM processor of the CPU transmits data to the PLOAM partition unit via the switch unit.

TWDM TC functions of the TWDM TC layer acquire data from embedded header fields via the switch unit. The TWDM TC functional unit of the TWDM TC layer transmits data to the embedded header area via the switch unit.

In the examples of FIGS. 2 and 3, the software area is the basic function section 132, the management/control agent section 133, the extended function section 131, and the middleware section 120, but the software area is the service adaptation (encryption) , fragment processing, GEM framing/XGEM framing, FEC of PHY adaptation, scrambling, synchronization block generation/extraction, GTC (GPON Transmission Convergence) framing, PHY framing, SP conversion, and encoding methods may also be targeted. An example of implementation of the software function of the architecture and an example of function deployment corresponding to the hardware unit 111 (PHY) and the hardware unit 112 (MAC) will be explained. Equipped with functions.

An OLT including a plurality of OSUs, switches, information processing units, and control units is assumed. Each OSU includes a different transmitter/receiver for each wavelength. In this case, a middleware section 120 is installed in each OSU and switch, and a software area such as a device-independent application section 130 is installed in the information processing section.

The information processing unit, that is, the CPU executes the device-independent application unit 130. The device-independent application section 130 includes an extended function section 131 for OSU, an extended function section 131 for switch, and an extended function section 131 for control section. The extended function unit 131 for OSU is, for example, a power saving application, a protection application, a DBA application, and an ONU registration authentication application. The extended function unit 131 for the switch is, for example, an MLD proxy application. The extended function unit 131 for the control unit is, for example, a low speed monitoring application (OMCI), a low speed monitoring application (EMS-IF), and a setting/management application. The EMS is, for example, an OSS (Operation Support System).

G. In the case of 989.3, the results are as shown in FIGS. 20 and 22 to 24, for example. In the case of a DBA application, the middleware section 120 shown in FIGS. 2 and 3 or the basic function section 132 shown in FIGS. Operate the OAM engine (Embedded OAM Engine). Then, the transmitting/receiving unit, which is the hardware unit 111 (PHY) and the hardware unit 112 (MAC) of the PMD layer, receives the information according to the DBA application. Note that when the transmitter/receiver receives an uplink signal that does not follow DBA, it may not follow DBA application.

The information processing section is not limited to these softening functions, and may have other softening functions. The hardware unit 111 (PHY) and the hardware unit 112 (MAC) are not limited to a transmitting/receiving unit, an OSU, a switch, a control unit, and an information processing unit. For example, the information processing section may be included in the transmitting/receiving section, OSU, switch, or control section. Further, as shown in FIG. 7, the NNI (Network-Network Interface) side of the switch may be provided with a proxy unit or an external server that processes signals input to and output from the switch. The external server 16 may be an information processing function called a cloud, such as a data center equipped with a plurality of devices.

Each function may be arranged as appropriate depending on processing capacity and processing delay requirements. Further, the OSU may include the switch unit 12 or the switch unit 13, or may include a separate switch (switch unit 12 when the switch unit 13 is included). It is desirable that the functions of the switch be shared between the switch units 12 and 13 as appropriate according to the processing capacity of the switch, etc., without duplication, but they may overlap.

The location where the softwareization function is provided is not limited to the information processing unit, but may be located at a location where a plurality of arithmetic operations can be performed. For example, the software functions are installed in the transmitting/receiving section, OSU switch, non-OSU switch, OLT control section, OLT switch, OLT information processing section, OLT switch and control section, and other than the information processing section. The NNI side of the switch may be a processing device such as a proxy unit or an external server that processes signals input to and output from the switch.

Furthermore, the softening functions may be arranged for each softening function, or may be part of a softening function obtained by dividing a single softening function. For example, things related to the transmitting/receiving unit may be placed in other parts other than the transmitting/receiving unit, such as a switch of the OSU, a part other than the transmitting/receiving unit of the OSU and other than the switch, a switch of the OLT, a control unit of the OLT, an information processing unit of the OLT, or other parts of the OLT. It may be deployed somewhere outside the OLT, such as a proxy unit, an external server, etc. on the path of the main signal, or a combination of multiple deployment locations. Regarding PON termination, place other than the PON termination processing location, for example, OSU transmitting/receiving section, OSU switch, OSU transmitting/receiving section and other than the switch, OLT switch, OLT control section, OLT information processing section. , the OLT, a proxy section on the main signal path outside the OLT, an external server, etc., or a combination of a plurality of deployment locations.

Regarding ONU switches, refer to other parts other than ONU switches, such as transmitting/receiving section, OSU transmitting/receiving section and other than switches, OLT switch, OLT control section, OLT information processing section, other parts of OLT, OLT It may be deployed somewhere outside of the main signal path, such as a proxy unit, an external server, etc., or a combination of multiple deployment locations. Regarding OLT switches, refer to other parts other than OLT switches, such as transmitting/receiving section, OSU switch, OSU transmitting/receiving section and other than switches, OLT control section, OLT information processing section, other parts of OLT, OLT It may be deployed somewhere outside of the main signal path, such as a proxy unit, an external server, etc., or a combination of multiple deployment locations.

Further, the location where the softwareization function is provided may be changed as appropriate depending on the deployment status of the extended function unit 131, the computing power, computing load, power consumption, etc. of the location where calculations are possible.

The main functions related to main signal processing of the OLT and the relationship between the functions will be explained. Transfer the OLT function to a switch. A PON main signal processing function that performs PON section processing such as a PHY adaptation function, a framing function, and a service adaptation function is provided in the transmitting and receiving unit. PON access control functions such as ONU registration or authentication function, DBA control function, and DWA function are provided in the information processing unit. The switch is equipped with L2 main signal processing functions such as VLAN control used in framing, priority control before the shaper, Mux/DMux and Queue, and a shaper before the framing.

The switch is equipped with multicast functions such as a copy function before the shaper and an MLD proxy used for copy. In this way, by providing the PON main signal processing function and PON access control function, which were provided in the PON, in the switch, the PON basic function section is reduced. In particular, it is preferable to avoid duplication of L2 main signal processing and deploy it in a switch.

The following example assumes that the switch functions are provided in the following order: Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, and Scheduler. However, it may be changed as appropriate. For example, in the upstream direction, if processing is not performed within the band allocation unit, the input from the ONU is removed from the preamble and burst overhead for burst transmission, the frame is decapsulated, and the LLID is removed. It is also possible to perform all the functions of Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, and Scheduler on a switch, or use a switch to perform Modifier, Cross Connect, Queue, and Scheduler. Only r may be implemented.

Furthermore, if the ONU assigns a VID or the like that describes the path after PON termination, then Cross Connect, Queue, and Scheduler can be used. If the upper network can be regarded as a single path, Queue or Scheduler may be used. Further, if DBA is performed to prevent frames from colliding in Cross Connect, Classifier, Modifier, Policer/Shaper, and Cross Connect can be used. Furthermore, in the upstream direction, if processing is not performed within the bandwidth allocation unit, the input from the ONU is processed by removing the preamble and burst overhead for burst transmission, decapsulating the frame, and removing the LLID. If only the terminal is used, and the ONU is provided with a VID or the like that describes the path after PON termination, it is also possible to use only the cross connect.

Also, Classifier, Modifier, Policer/Shaper, Cross Connect, Queue, Scheduler, Classifier, Policer/Shaper, Modifier, Cross Connect, Queue , Scheduler, or by placing a Queue in front of Policer/Shaper, Classifier, Modifier, Queue, Policer/Shaper, Cross Connect, Scheduler, Classifier, Queue, Policer/Shaper, Modifier, Cross Connect, Scheduler You may also Considering unnecessary Policing/Shaping caused by PON burst transmission and multiplexing of prioritized traffic such as multicast, and reception of leveled traffic on the receiving side, Policer/Shaper It is desirable to place a Queue at the front stage and perform the Policing/Shaping process after leveling.

When making a state transition to a specific state, the entity performing the sleep operation, etc. stores the instructions from the entity (equipment included in the communication device) externally, which is independent from the entity performing the sleep operation, etc. It becomes possible to inherit the behavior. The specific state is, for example, a sleep state, a switching state of an active communication device, a user accommodation switching state, and a multicast state. Since the information is held outside the communication device, it is possible to prevent inheritance of sleep operations and the like from being lost when switching to another communication device. The communication device can ensure the inheritance of information held by the device.

Further, by using a general-purpose, software-based switch as an execution unit, it is possible to realize an OLT that can add functions to the general-purpose, software-based switch at low cost, flexibly, and quickly.

The configuration according to Embodiment 1-1 shown above is the same in the following embodiments, and may be combined as appropriate. For example, in FIG. 2, this system illustrates a case where the configuration of the execution unit is only the transmitter/receiver 11 (TRx), the switch unit 12, and the switch unit 13; The execution unit may be a location other than 13, a location other than that, a location where the PON terminates, or the control unit 14.

(Embodiment 1-2)
In Embodiment 1-1, a configuration used in a TWDM-PON is illustrated, but the present invention may also be applied to a TDM-PON. TDM-PON is the same as Embodiment 1-1 except that it does not need to have a function such as λ setting switching (DWA) that wavelength division multiplexes wavelength resources in the PON section of ONU-OLT between ONUs. It is.

(Embodiment 1-3)
In Embodiment 1-1, a configuration used for TWDM-PON is illustrated, but the present invention may also be applied to WDM-PON. Embodiment 1-3 is similar to Embodiment 1-1, except that the WDM-PON does not need to have a function to time-division multiplex bandwidth resources in the PON section of ONU-OLT between ONUs such as DBA. It is similar to

(Embodiment 1-4)
This embodiment uses OFDM (Orthogonal Frequency Division Multiplex)-PON, CDM (Code Division Multiplex)-PON, SCM (Subcarrier Multiplex)-PON, and core wire. This is a combination including division multiplexing.

Although Embodiment 1-1 exemplifies a configuration used in a TWDM-PON, the present invention may also be applied to a PON that shares resources other than wavelength and time. For example, it may be applied to OFDM-PON, which divides and multiplexes one wavelength of electrical frequency resources, SCM-PON, which divides and multiplexes one wavelength of electrical frequency resources, CDM-PON, which divides and multiplexes by code. Multiplexing may be used together, space division multiplexing using a multi-core fiber or the like may be used together, or wavelength division multiplexing may not be used. The same applies if the function of wavelength division multiplexing the wavelength resources of the TWDM-PON is replaced with the function corresponding to the function required to divide and multiplex the respective multiplexed resources.

(Embodiment 2)
In embodiment 2, the configuration used in the TWDM-PON performs GEM encapsulation. In this case, the switch is equipped with an adapter that generates the GEM frame, and the GEM frame is made conductive between the switch and other parts. By transferring up to GEM encapsulation to the switch, it is possible to exclude the L2 functional part from the protocol stack of other parts, and avoid overlapping of the L2 functional part between the switch and other parts.

Although TWDM-PON is taken as an example, the same applies to other PONs as long as the frame for identification in the PON section is handled in the same way as in Embodiments 1-2 to 1-4. The effect of this can be obtained. For example, in the case of GE-PON, 10GE-PON, etc. according to the IEEE standard, instead of the GEM frame, you can add an LLID and use the frame with the LLID to conduct between the switch and other parts. good.

(Embodiment 3)
In the third embodiment, control information used for TWDM-PON passes through a switch. In this case, instead of transferring the bridge function to the switch, any one of PLOAM, Embedded OAM, and OMCI holding control information is framed as necessary and processed via the switch. Inputting and outputting control information via a switch has the effect of lightening processing other than the switch. Note that in addition to the transfer of the third embodiment, the bridge function of the first and second embodiments may be transferred to the switch.

Although TWDM-PON is taken as an example, if the control information is handled in the same way and processed via the switch, similar results can be applied to other PONs as in Embodiments 1-2 to 1-4. Effects can be obtained.
