Detailed ways

Before introducing the technical solutions of the embodiments of the present invention, related technologies are first described.

In related technologies, 5G systems need to support a variety of services, such as: Enhanced Mobile Broadband (eMBB, Enhanced Mobile Broadband) services with higher bandwidth and lower latency, Internet of Things (mMTC, Massive Machine-Type) services that support massive user connections. Communication) services, as well as ultra-reliable, ultra-low latency (uRLLC, ultraReliable & Low Latency Communication), etc. 5G systems also need to support a variety of application scenarios, such as: ubiquitous HD/UHD or even three-dimensional (3D) holographic films and videos in dense urban areas, high-speed user experience of 100Mbps anywhere, high-speed mobile applications greater than 350km/h, transmission Sensor network, tactile Internet, E-Health, natural disaster monitoring, etc. In the 5G system, it is also necessary to support packet transmission of different service types. In order to meet network requirements such as large bandwidth, low latency, hard isolation, flexible connection, unified management and control, and high-precision time synchronization, it can be based on the slicing and packet network mechanism. The channels between the SPN devices transmit different types of service packets. Specifically, the SPN device obtains the service packets through the input port, that is, the UNI interface, and performs conversion processing on the service packets, such as 64B/66B encoding and decoding processing. Through the output port of the SPN device, that is, the NNI interface, the service packet is transmitted to the channel connecting the SPN device and other SPN devices, and finally sent to other SPN devices.

Fig. 1 is a schematic diagram of SPN equipment using channels to realize data forwarding in the related art. As shown in Fig. 1, the transmission path of service packet A is SPN0-SPN1-SPN2-SPN3; the transmission path of service packet B is SPN0-SPN1- SPN2-SPN4, assuming that service packet A and service packet B are of the same type, when the same service packet is transmitted between SPN0 and SPN1, two independent channels need to be established, and the two channels cannot be shared. It can be seen that the utilization rate of the channel of the SPN device is not high, so the transmission efficiency of service packets is low.

Based on this, in various embodiments of the present invention, the first information is sent to the SPN device; wherein, the first information at least represents the correspondence between the input channel and the output channel of the SPN device; the first information uses It is used for the SPN device to multicast and send the service message.

With the solution of the embodiment of the present invention, there is a clear correspondence between the input channel and the output channel of the SPN device. In this way, when multiple SPN devices perform multicast transmission (one-to-many transmission) on service packets, the two When the same type of service packets are transmitted on the channel between SPN devices, there is no need to occupy multiple independent input channels. In this way, the problem of low utilization rate of the channel of the SPN device is solved, and the waste of resources is avoided.

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

An embodiment of the present invention provides a packet transmission method, which is applied to an SDN device. As shown in FIG. 2 , the method includes:

Step 201: Send the first information to the SPN device;

Wherein, the first information at least represents the corresponding relationship between the input channel and the output channel of the SPN device; the first information is used for the SPN device to perform multicast sending of service packets.

Here, in practical application, in step 201, the SPN device for multicast sending the service packet may mean that the SPN device sends the service packet to multiple receivers after receiving the service packet device; the receiving device may refer to other SPN devices other than the SPN device.

Here, when a channel between two SPN devices is used for inputting service packets, it may be called an input channel, and when a channel between two SPN devices is used for outputting service packets, it may be called an output channel.

Here, the correspondence between the input channel and the output channel of the SPN device may refer to that one input channel of the SPN device corresponds to multiple output channels. In the case where the correspondence between the input channels and the output channels of the SPN devices is one-to-many, there is no need to establish multiple independent channels between every two SPN devices. In other words, when the same service packet is transmitted between every two SPN devices, there is no need to occupy multiple independent channels. In this way, when multicast transmission of service packets is performed, there is no need to occupy multiple independent input channels. In this way, The utilization rate of the channel of the SPN device is improved, and the waste of resources is avoided.

In the embodiment of the present invention, the SDN device may specifically refer to an SDN management and control platform, or may refer to an EMS network management device.

In practical application, if the SDN device is configured with the multicast function for the SPN device, the SPN device has the function of supporting multicast, so that the service packet can be subsequently multicast transmitted. If the SDN device is not configured with the multicast function for the SPN device, the SPN device does not have the function of supporting multicast, so that the service packet can be unicast transmitted subsequently.

Based on this, in one embodiment, the method further includes:

Configure a multicast group for the SPN device.

Here, configuring a multicast group for the SPN device may refer to configuring a corresponding multicast group identifier for the SPN device. If the SPN device is configured with a multicast group identifier, the SPN device has the function of supporting multicast; if the SPN device is not configured with a multicast group identifier, the SPN device does not have the function of supporting multicast.

For example, as shown in Figure 3, if SPN0 is not configured with a multicast group ID, SPN0 does not have the function of supporting multicast; SPN1 is configured with a multicast group ID, such as multicast group 1, then SPN1 has the function of supporting multicast ; SPN2 is configured with a multicast group ID, such as multicast group 2, SPN2 has the function of supporting multicast; SPN3 is configured with a multicast group ID, such as multicast group 3, then SPN3 has the function of supporting multicast, as shown in Table 1 shown.

SPN equipment multicast group ID Whether to support multicast function SPN0 none no SPN1 multicast group 1 Yes SPN2 multicast group 2 Yes SPN3 multicast group 3 Yes

Table 1

Here, the SDN device configures a multicast group for the SPN device, which has the following advantages:

It can identify whether the SDN device has the function of supporting multicast. In this way, if the SPN device has the function of supporting multicast, the subsequent SPN device can enable the multicast function when transmitting multicast packets, and multicast the multicast packets. Transmission; if the SPN device does not have the function of supporting multicast, the subsequent SPN device does not need to enable the multicast function when transmitting unicast packets, and only needs to broadcast the unicast packets. Thus, the multicast and broadcast functions of the SPN device can be realized, and the flexible transmission of different types of service packets can be realized.

In practical applications, in order to transmit service packets between SPN devices, a channel for transmitting service packets may be configured for the SPN devices.

Based on this, in one embodiment, the method further includes:

Configure the channel for the SPN device.

Among them, there is only one channel between every two SPN devices, and this channel may be called an SE channel, or an SE L1 channel.

For example, as shown in FIG. 3, there is one channel between SPN0 and SPN1, one channel between SPN1 and SPN2, and one channel between SPN1 and SPN3.

In practical application, the channel type of the SPN device, such as input channel and output channel, needs to be configured according to the transmission direction of service packets.

Based on this, in one embodiment, the method further includes:

An input channel and an output channel corresponding to the multicast group are configured for the SPN device.

The channel between the two SPN devices is used for inputting service packets, and the channel may be called an input channel; the channel between the two SPN devices is used for outputting service packets, and the channel may be called an output channel.

In practical application, if the corresponding relationship between the multicast group, input channel, and output channel of the SPN device is configured, the SPN device can perform multicast transmission based on its own multicast group, service The input channel of the message is determined by at least two corresponding output channels, and the service message is sent to the corresponding at least two receiving devices through the at least two output channels.

Based on this, in one embodiment, the method further includes:

Establish the correspondence between the multicast group, input channel and output channel of the SPN device;

The established correspondence between the multicast group, the input channel and the output channel is carried in the first information.

For example, as shown in Table 2, SPN0 is not configured with a multicast group ID, and the output channel is represented by number 0; the multicast group ID of SPN1 is multicast group 1, the input channel is represented by number 0, and the output channel is represented by 1 and 2 indicates; the multicast group of SPN2 is identified as multicast group 2, the input channel is represented by number 1, and the output channel is represented by 3 and 4; the multicast group of SPN3 is identified as multicast group 3, the input channel is represented by number 2, and the output channel is represented by number 2. Denoted by 5 and 6.

SPN equipment multicast group ID input channel output channel SPN0 none none 0 SPN1 multicast group 1 0 1, 2 SPN2 multicast group 2 1 3, 4 SPN3 multicast group 3 2 5, 6

Table 2

Here, the SDN device configures the correspondence between multicast groups, input channels, and output channels for the SPN device, which has the following advantages:

In the process of multicast transmission of service packets by the SPN device, the SPN device can determine at least two corresponding output channels based on its own multicast group and the input channel of the service packets, and transmit the service packets through the at least two output channels. The message is sent to at least two corresponding receiving devices, so as to realize the multicast transmission function of the SPN.

In practical applications, the SPN device may include one input port and multiple output ports, the input ports may correspond to input channels, and the multiple output ports may correspond to multiple output channels one-to-one.

Based on this, in one embodiment, the method further includes:

An input port and an output port corresponding to a multicast group are configured for the SPN device; the input port corresponds to an input channel; and the output port corresponds to an output channel.

Based on this, in one embodiment, the method further includes:

Establish the correspondence between the multicast group, input port and output port of the SPN device;

The established correspondence between the multicast group, the input port and the output port is carried in the first information.

If the input port of the SPN device is connected to the input channel, the SPN device can receive service packets input from the input channel based on the input port; the output port of the SPN device is connected to the output channel, then the SPN device can output service packets based on the output port to the On the corresponding output channel, it is finally sent to other SPN devices.

With the solution of the embodiment of the present invention, there is a clear correspondence between the input channel and the output channel of the SPN device. In this way, when multiple SPN devices perform multicast transmission (one-to-many transmission) on service packets, the two When the same type of service packets are transmitted on the channel between SPN devices, there is no need to occupy multiple independent input channels. In this way, the problem of low utilization rate of the channel of the SPN device is solved, and the waste of resources is avoided.

Correspondingly, an embodiment of the present invention also provides a packet transmission method, which is applied to an SPN device. As shown in FIG. 4 , the method includes:

Step 401: Receive first information sent by an SDN device; the first information at least represents a correspondence between an input channel and an output channel of the SPN device;

Step 402: After acquiring the service message, according to the first information, determine at least two output channels corresponding to the input channel of the service message;

Step 403: Send the service message to the receiving devices corresponding to the at least two output channels respectively.

Here, the correspondence between the input channel and the output channel of the SPN device may refer to that one input channel of the SPN device corresponds to multiple output channels. In the case where the correspondence between the input channels and the output channels of the SPN devices is one-to-many, there is no need to establish multiple independent channels between every two SPN devices. In other words, when the same service packet is transmitted between every two SPN devices, there is no need to occupy multiple independent channels. In this way, when multicast transmission of service packets is performed, there is no need to occupy multiple independent input channels. In this way, The utilization rate of the channel of the SPN device is improved, and the waste of resources is avoided.

In practical applications, after the SPN device receives the service packet, if the type of the service packet is a multicast packet, the SPN device can multicast the service packet; if the type of the service packet is not a multicast packet When the message type is specified, the SPN device can unicast the service message.

Based on this, in an embodiment, the determining at least two output channels corresponding to the input channel of the service packet according to the first information includes:

Obtain the identification information of the service message;

determining the type corresponding to the identification information of the service message according to the correspondence between the message identifier and the message type;

Determine whether the determined type matches the preset type;

When the determined type matches the preset type, at least two output channels corresponding to the input channel of the service message are determined according to the first information.

For example, if the value of the field corresponding to the identification information of the service packet is 0, it indicates that the type of the service packet is a multicast packet. If the value of the field corresponding to the identification information of the service packet is 1, then Indicates that the type of service packets is unicast packets.

In practical application, if the SPN device has the function of supporting multicast, after determining that the type of the service packet is the multicast packet type, the multicast function can be enabled to perform multicast transmission of the service packet; if the SPN device does not With the function of supporting multicast, there is no need to enable the multicast function, and unicast transmission of service packets can be performed.

When the determined type matches the preset type, the multicast function is enabled;

According to the first information, at least two output channels corresponding to the input channels of the service message are determined.

In practical application, after it is determined that the service packet type is a multicast packet type and the multicast function is enabled, the SPN device can multicast the service packets according to the corresponding relationship between multicast groups, input channels, and output channels.

At least two output channels corresponding to the channel, including:

Determine the first multicast group corresponding to the current SPN device;

determining at least two output channels corresponding to the first multicast group according to the first information;

The determined at least two output channels are used as at least two output channels corresponding to the input channels of the service message.

Wherein, the first multicast group may be the multicast group identifier of the current SPN device. The multicast group identifier of the current SPN device may be carried in the service message. The service message may also carry the identifier of the input channel of the current SPN device.

Here, at least two output channels corresponding to the first multicast group are determined according to the first information, which specifically includes the following two cases:

In the first case, the service packet carries the multicast group identifier.

Specifically, the multicast group identifier carried in the service packet is taken as the first multicast group of the current SPN device; corresponding at least two output channels.

For example, assuming that the service packet carries the multicast group identifier as multicast group 1, it is obtained by looking up Table 2 that the output channels corresponding to the current SPN device SPN1 are output channel 1 and output channel 2.

In the second case, the service packet carries the identifier of the input channel of the current SPN device.

Specifically, according to the correspondence between the multicast group, the input channel and the output channel of the SPN device, and the identifier of the input channel of the current SPN device carried in the service message, determine at least two outputs corresponding to the input channel of the service message aisle.

For example, it is assumed that the service packet carries the identifier of the input channel as input channel 1, and the output channel corresponding to the current SPN device SPN1 is obtained by looking up table 2 as output channel 3 and output channel 4.

In practical applications, after determining that the service packet type is the multicast packet type and enabling the multicast function, the SPN device can also send the service packet to other multiple based on the corresponding relationship between the multicast group and the input port and output port. SPN device.

Based on this, in an embodiment, the first information further represents the correspondence between the multicast group of the SPN device and the input port and the output port; the sending the service packet to the at least two output channels The corresponding receiving devices, including:

Duplicating the service message to obtain the duplicated service message;

Determine the first multicast group corresponding to the current SPN device;

determining at least two output ports corresponding to the first multicast group according to the first information;

Through the at least two output ports, the duplicated service message is transmitted to the at least two output channels in a time-division multiplexing manner, and sent to the corresponding receiving device through the at least two output channels.

The SPN device can transmit the duplicated service packets to the at least two output channels in a time-division multiplexing manner through at least two output ports, namely NNI interfaces, and send them to the corresponding receivers through the at least two output channels. equipment.

Figure 5 is a schematic diagram of the SPN device forwarding service packets to other SPN devices through the NNI interface. As shown in Figure 5, on the NNI interface of the SPN device, the service packet can be fragmented to obtain multiple data fragments. Each data segment is bound to the corresponding time slot, and each data segment is sent to other SPN devices using a time division link.

FIG. 6 is a schematic diagram of the NNI interface, and the NNI interface can be implemented based on the FlexE interface. The FlexE interface can be implemented in the PCS layer of the 100GBASE-R protocol stack. Each FlexE interface can include MAC, reassembly sublayer and XMII. The modules above the FlexE interface run at the rate of the FlexE interface; the parameters of the modules below the FlexE interface are not modified, and the modules below the FlexE interface include 100GBASE-R PMA, optional FEC and PMD.

In an example, as shown in FIG. 7 , the process of multicast forwarding of service packets by the SPN device is described, including:

Step 701: Receive a service message through an input port;

Step 702: determine whether it is a multicast message; when it is determined to be a multicast message, execute step 703;

Step 703: Determine whether to enable the multicast function, and after the multicast function is enabled, perform step 704;
