Abstract

The embodiment of the invention provides a message forwarding method and device. A forwarding table item of a main / standby topology for forwarding a message from a head node to a target node is maintained in the head node; Wherein the forwarding table items of the main topology comprise a main forwarding table item corresponding to the main path and a first standby forwarding table item corresponding to the first standby path; Wherein the forwarding table item of the standby topology comprises a second standby forwarding table item corresponding to the second standby path; When the head node forwards the message based on the forwarding table entry of the main topology, the communication states of the main path and the first standby path are detected through BFD session connection established between the head node and the destination node on the main path and between the head node and the first PQ node on the first standby path respectively; And if the main path and the first standby path fail, switching the main topology and the standby topology, and forwarding the message based on the switched forwarding table entry of the standby topology. According to the message forwarding method, the service recovery speed is increased, and the problem of a large amount of packet loss caused by the fact that the destination node configures the monitoring link group is relieved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a message forwarding method and device. Background technique [0002] The head node forwarding the message can forward the received message to the destination node, so as to realize message forwarding. During the message forwarding process, the head node maintains in advance the main path for different destination addresses, and forwards the message based on the main path. [0003] In order to ensure the reliability of message forwarding, the head node also maintains a backup path. When the primary path for forwarding packets fails, the head node can switch to the standby path for packet forwarding. However, in some special scenarios, for example, in order to quickly switch to other special services, the destination node needs to configure a monitoring link group, and the monitoring link group independently performs linkage between the main path and the ba...
