Patent ID: 7787362

Claim:
A method for recovering a shared mesh network, comprising: a network management system sending a connection establishment request message to a network ingress node of a network connection server; parsing the connection establishment request message received by the network ingress node; if the request message carries routing information of a working path and a recovery path having strict explicit routes, taking, by the network ingress node, the routing information carried in the request message as the routing information of the working path and the recovery path, and saving the routing information of the recovery path carried in the request message; if the request message carries no routing information of a working path and/or a recovery path, computing, by the network ingress node, a route of the working path and/or a route of the recovery path, and saving, by the network ingress node, the computed routing information of the recovery path; after the working path is successfully established, returning, by the network ingress node, a message “working path connection establishment successful” to the network management system; obtaining, by the network management system, the routing information of the recovery path after receiving the message “Working Path Establishment Successful” sent by the network ingress node; determining, by the network management system, a link that the recovery path passes according to the obtained routing information of the recovery path and determining whether resources need to be reserved for the link; controlling resource reservation of the recovery path by the network management system according to this determination result; initiating an establishing procedure of the recovery path by the network ingress node of the network connection service by using reserved resources according to the saved routing information of the recovery path, after the working path is interrupted; and switching services on the working path to the recovery path for transmission.
