Title: METHOD, NETWORK DEVICE, AND NETWORK SYSTEM FOR PROCESSING DCN MESSAGE
Abstract:
The present application provides a method, a network device, and a network system for processing a DCN message. The method for processing a DCN message comprises: a network device generating a first DCN message, of which a destination address is an IP address of an NMS; loading the first DCN message in an Flex Eth overhead multiframe; transmitting via a physical link the Flex Eth overhead multiframe to a network device that has accessed a network; extracting the first DCN message from the network device that has accessed the network; and transmitting, based on the destination address, the first DCN message to the NMS, such that the NMS senses that a new network device accesses the network. The process does not require technicians to perform on-site manual configuration and maintenance on a network device newly accessing a network, reducing manpower, material resources, and maintenance costs. In addition, because the process of transmitting a first DCN message is performed via a physical link, no human operations are involved, and mistakes are not easily made, further improving the efficiency of a network device accessing a network.
