Abstract

A fast rerouting method for automatically exchanging optical network, each node detectes several alarm conditions in all links of the node in time. When a fault of link be detected, the node searches a traffic beared at the failed link with fault, if the traffic exists, the node sends a signaling information including failed link information to a source node of the traffic sequentially. After detecting the failed traffic and receiving the signaling information, according to the restoration policy, the current node acts as the resource, the service destination node acts as the destination, the source node caculates the restoration route newly, the resource node connected with service begins to restore the signaling course of routing establishment. According to the described method in the present invention, it reduces the need of the link resource of network topology, avoids the blindness of selecting the restoration route channel, improves the success rate of service restoration , and shortens the service restoration time.
