Classification: CPC H | IPC H

Claim 0:
1. A data communication network (DCN) packet processing method, wherein the method comprises:
generating, by a first network device, a first DCN packet that includes a destination address and a payload, wherein the first network device and a second network device are connected using a physical link, and the DCN includes a network management system (NMS) communicatively coupled to the second network device;
monitoring, by the first network device, a state of a Flex Ethernet client, and determining that the state of the Flex Ethernet client is not a conducted state:
adding, by the first network device, the first DCN packet into a flexible Ethernet (Flex Ethernet) overhead multiframe; and
sending, by the first network device, the Flex Ethernet overhead multiframe to the second network device by using the physical link, so that the second network device extracts the first DCN packet from the Flex Ethernet overhead multiframe, and forwards the first DCN packet to the NMS according to the destination address;
generating, by the first network device, a second DCN packet that includes the destination address;
monitoring, by the first network device, the state of a Flex Ethernet client, and determining that the state of the Flex Ethernet client is the conducted state; and
sending, by the first network device, the second DCN packet to the second network device through the Flex Ethernet client according to the destination address.
