DCN PACKET PROCESSING METHOD, NETWORK DEVICE, AND NETWORK SYSTEM
First Claim
1. A data communication network (DCN) packet processing method, wherein the method comprises:
- generating, by a first network device, a first DCN packet, wherein a destination address of the first DCN packet is an IP address of a network management system (NMS), a next hop through which the first DCN packet passes to arrive at the destination address of the first DCN packet is a second network device, and the first network device and the second network device are connected by using a physical link;
loading, 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.

Abstract
This application provides a DCN packet processing method, a network device, and a network system. The DCN packet processing method includes: generating, by a network device, a first DCN packet whose destination address is an IP address of an NMS, loading the first DCN packet into a Flex Eth overhead multiframe, and sending, over a physical link, the Flex Eth overhead multiframe to a network device that has accessed a network, so that the network device that has accessed the network extracts the first DCN packet, and sends the first DCN packet to the NMS based on the destination address, so as to enable the NMS to perceive that a new network device accesses the network.

5. 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 cause the first network device to be configured to; generate a first data communication network (DCN) packet, wherein a destination address of the first DCN packet is an IP address of a network management system (NMS), a next hop through which the first DCN packet passes to arrive at the destination address of the first DCN packet is a second network device, and the first network device and the second network device are connected by using a physical link; 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. - View Dependent Claims (6, 7, 8)

9. A network device, used as a second network device, wherein the second network device comprises:
-
a memory comprising instructions; one or more processors coupled to the memory, wherein the instructions cause the first network device to be configured to; receive a flexible Ethernet (Flex Ethernet) overhead multiframe sent by a first network device over a physical link, and extract a first data communication network (DCN) packet from the Flex Ethernet overhead multiframe, wherein a destination address of the first DCN packet is an IP address of a network management system (NMS), the second network device is a next hop through which the first DCN packet passes to arrive at the destination address of the first DCN packet, and the second network device and the first network device are connected by using the physical link; and send the first DCN packet to the NMS based on the destination address. - View Dependent Claims (10, 11)
