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.

摘要： A method of establishing a bi-directional Label Switched Path (LSP) includes an establishing request and available upstream and downstream label sets are sent from a first node to a terminal node of the LSP node-by-node. If the available upstream or downstream label set obtained by the terminal node or other nodes is null, the LSP can't be established; if the establishing request is sent to the terminal node and the received available upstream and downstream label sets are not null, the terminal node chooses an upstream label and an downstream label. An establishing response and the upstream and downstream labels are sent from the terminal node to the foregoing nodes node-by-node, and each of other nodes except the first node chooses an upstream label and a downstream label to an upstream node according to the upstream and downstream labels provided by the downstream node.
