<p>A method, a system and a device for service recovery in the technical field of communications. The method includes the following steps: service resources of one traffic engineering link in a network are set as a shared mesh network (MESH) recovery state (202); said shared MESH recovery state information is flooded to the network (203), where it is used to notify that the failure recovery mode for the service resources of the traffic engineering link is a segment-level shared MESH recovery. It is next detected whether the traffic engineering link has failed, and in this event, service in the service resources of the traffic engineering link is recovered by switching N segment-level forwarding adjacency label switched paths (FA-LSP) to a corresponding N segment-level shared MESH recovery paths (205). The invention can reduce service recovery time and satisfy user service requirements under conditions of optimal bandwidth resource utilization.</p> |
