Method and device for recovering a shared mesh network

摘要

One embodiment of the present invention discloses a method and device for recovering a shared mesh network. The core idea of the method lies in that: a network ingress node of network connection service determines and saves routing information of a recovery path; after a working path is established successfully, a network management system controls resource reservation of the recovery path; and after the working path is interrupted, the network ingress node of the network connection service initiates an establishing procedure of the recovery path by using the reserved resources according to the saved routing information of the recovery path, and switches services on the working path to the recovery path for transmission. The technical solutions of the invention are easy to implement, and can be realized by using existing protocols; moreover, it can be well compatible with existing devices.
