DCN packet processing method, network device and network system

摘要

The present application provides a DCN packet processing method, a network device, and a network system. The DCN packet processing method includes the steps of: generating a first DCN packet whose destination address is the IP address of the NMS; loading the first DCN packet into a FlexEth overhead multiframe; Transmitting a Flex Eth overhead multiframe over a physical link, so that the network device accessing the network extracts the first DCN packet and transmits the first DCN packet to the NMS based on the destination address. , Thereby allowing the NMS to recognize that the new network device has access to the network. This process eliminates the need for technicians to perform manual configuration, operation, and maintenance of network devices that newly access the network, thereby reducing human resources, physical resources, and operation and maintenance. Reduce costs. In addition, the process in which the first DCN packet is transmitted over the physical link requires no manual operation and is less likely to encounter errors, thereby further improving the network access efficiency of the network device.
