Abstract

The embodiment of the invention discloses a fault detection method and device for a network path and network equipment. The method comprises the following steps: determining a target network path between an initiating device of path detection and a destination device of the path detection by a control plane; generating a detection message and path information, wherein the detection message is used for indicating the destination device to return a response message, and the path information comprises an identifier used for representing the target network path and a level; and transmitting the detection message and the path information to a forwarding plane, so that the forwarding plane transmits the detection message to the destination device through the target network path. By adopting the embodiment of the invention, the detection of the network path can be performed quickly and customer services are not affected basically.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a network path fault detection method, device, and network equipment. Background technique [0002] The communication network built based on message forwarding equipment generally has backup paths for protection of important services. When the main path for transmitting services fails, the service transmission path is switched from the main path to the backup path. Specifically, fast rerouting (Fast Reroute, FRR for short) may be used to implement service protection and switching. However, if an abnormality occurs on the backup path, resulting in a handover failure, it will seriously affect the transmission of services and cause losses to users. Therefore, fault detection needs to be performed regularly to determine whether the backup path is normal, so that when the main path fails and needs to be switched to the backup path, the backup...
