Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A network device, used as a first network device, wherein the first network device comprises:
a memory comprising instructions;
one or more processors coupled to the memory, wherein the instructions, when executed by the one or more processors, cause the first network device to be configured to:
generate a first data communication network (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;
monitor a state of a Flex Ethernet client, and determining that the state of the Flex Ethernet client is not a conducted state;
load the first DCN packet into a flexible Ethernet (Flex Ethernet) overhead multiframe; and
send the Flex Ethernet overhead multiframe to the second network device over 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,
generate a second DCN packet that includes the destination address;
monitor the state of a Flex Ethernet client, and determining that the state of the Flex Ethernet client is the conducted state; and
send the second DCN packet to the second network device through the Flex Ethernet client according to the destination address.
