Embodiment one, a self-adapting device of business single board
As shown in fig. 1, the present embodiment mainly includes a detection module 110 and a processing module 120, wherein:
a detection module 110 for receiving an input signal inputted from the outside, identifying a service type of the input signal by detecting a framing format of the input signal, and notifying a recognition result to the processing module 120; byte information in frame structures of input signals of different services is different, so that the input signals of different service types can be identified by comparing the byte information in the frame structures of the input signals;
a processing module 120, connected to the detection module 110, for converting the input signal into an output signal of a frame structure of a line side service according to a service type of the input signal; specifically, the Optical Transport Network (OTN) processing of Forward Error Correction (FEC) decoding, overhead, framing, and the like of the input signal is performed, and finally, the frame structure of the line-side service is converged or converted into a related maintenance signal as required, and the related maintenance signal is connected to the group side optical module through an interface, and is output after electrical/optical (E/O) conversion by the group side optical module.
As shown in fig. 1, the embodiment may further include a network management unit (MCU)130, respectively connected to the detection module 110 and the processing module 120, configured to set a service configuration mode, including a service adaptive configuration mode or a service non-adaptive configuration mode; the detection module 110 recognizes the service type of the input signal and then notifies the MCU 130 of the recognition result. When the MCU 130 is configured to be service adaptive, the processing module 120 may execute the corresponding processing according to the notification of the MCU 130. In other embodiments, if the MCU 130 is configured as a service non-adaptive configuration (i.e., a conventional manual configuration is a master), the processing module 120 performs subsequent series of processing on the input signal (FEC decoding, overhead, framing, etc. processing of the input signal and converging into a frame structure of the line-side service, etc.) according to a signal format preset by the MCU 130, for example, the input signal is an OTU2 signal, and the service signal set by the MCU 130 is an STM-64 signal, at this time, the processing is performed according to a Synchronous Digital Hierarchy (SDH) processing method, such as decoding, overhead, framing, etc., and finally converged into a frame structure of the OTU3 or converted into a related maintenance signal as required, and the frame structure is connected to the group-side optical module through an interface, and the group-side optical module performs E/O conversion and outputs the result. In this case, the subsequent result may be that the set STM-64 service is not matched with the accessed OTU2 service, the service cannot be connected, and the service board reports an alarm.
In this embodiment, the MCU 130 is configured as a service adaptive configuration, and if the services are not matched, different alarms are reported according to the service types, for example, if the services are not matched, a frame loss LOF alarm is reported for SDH service, and if the services are not matched, a frame loss OUT-of-sync (OUT-LOF) alarm is reported for OTN service, and a synchronization loss alarm is reported for ethernet service.
After identifying the service type of the input signal, the detection module 110 needs to compare with the initial service type stored by the board, and if the service type of the input signal is the same, the adaptation is successful; if the input signal is different from the service format of the access service format, the report is sent to the network management unit 130, and the network management unit 130 issues a change command according to the service format of the input signal, so that the service format is finally matched with the access service format.
In a practical application of the present invention, taking a 40G convergence service board as an example, the detection module 110 is connected to an external XFP (10 Gigabit Small Form Factor Pluggable) optical module, and the received input signal is an electrical signal obtained by performing photoelectric conversion on an optical signal accessed by a client side by using an XFP optical module, which is a client side optical module.

The service single board self-adapting system realizes the monitoring judgment of the service and the switching management of the self service by installing a monitoring management chip, the data collected by the chip is reported to the MCU 130 of the single board and the network element management single board, and the network element management unit sends a command to start the service self-adapting process after comparing the previously stored data with the reported data.
The practical application of the invention comprises the application of a 40G convergence service single board, and the service types which can be accessed by the branch side interface of the 40G convergence service single board are as follows: STM-64(OC-192), 10 GE-local area network/wide area network (LAN/WAN), and OTU2, and four branches may access four identical traffic signals, or different branches may receive different types of traffic signals. The service type that the group side can access is OTU 3.

For example, in engineering provisioning and maintenance, a large number of services need to be set, and at this time, if adaptive management of the services is adopted, the setting and maintenance time can be greatly saved. Or, when a new service needs to be accessed or a service needs to be replaced, the prior art cannot continue to operate when the service set by the board cannot be judged for some reasons, and the engineering can be smoothly performed by using the technology of the present invention.
