Abstract

The invention provides a communication method and a communication device. The method comprises the following steps: when an intermediate node in an SR-TE tunnel path senses an error code fault, basedon existing operation, administration and maintenance OAM messages, an error code switching function is expanded and supported, that is, identification information used for identifying signal degradation of the SR-TE tunnel is carried in the OAM messages, it is guaranteed that the SR-TE tunnel supports the intermediate node error code switching function, and customer service damage can be effectively avoided.

Description

technical field [0001] The present application is in the communication field, and in particular, relates to a network communication method and device. Background technique [0002] Automatic protection switching (English: automatic protection switching, APS) is a protection mechanism that when a communication device at one end finds that the currently used communication channel is faulty, it sends an APS request through an APS message and cooperates with the opposite end device to switch the communication channel. [0003] The segment routing traffic engineering (English: Segment Routing Traffic Engineering, SR-TE) tunnel is based on segment routing (English: Segment Routing) to guide path forwarding. When a packet enters the network, the source node adds an instruction set (also called a label stack) to guide forwarding in the packet header, and subsequent nodes query the forwarding table according to the instruction (also called a label) to obtain the next hop and outgoing...
