Assuming that the size of data to be transmitted is a and the bandwidth on the transmission path is B, the following two cases are possible:
1) a & ltB & gt, the bandwidth can meet the transmission requirement at the moment, a main control CPU receives service requests sent by a plurality of terminals at the same time, and the service requests comprise terminal numbers of target terminals and administrative unit identifications;
according to the height of the administrative unit identifier, the data packets with high priority can be sent through the video networking protocol, the data packets with low priority can be sent through the 5G link, for example, the data packets with provincial level are sent through the video networking protocol, the data packets with village level identifiers are sent through the 5G link, therefore, the service with high priority is guaranteed, and a part of the service with low requirement for delay is sent through the 5G link, so that the user experience is improved.
2)A>B
At this time, the transmission bandwidth cannot meet the transmission requirement, and for one service, assuming that a-B is equal to M, the excess M must be transmitted through 5G. In the data forwarding module, after the data of the M part is converted into IP data through the protocol conversion module, the IP data is sent to the opposite terminal through the 5G module.
In the process of sending data through different channels, a complete data stream needs to be split into two parts, one part passes through the video network, the other part passes through the 5G, under the condition, the data forwarding module can code the data needing to be split, meanwhile, the coding rule is transmitted to the target terminal, and at the terminal at the opposite end, the video network and the 5G data are integrated according to the coding rule to obtain a complete data packet.
