Control method for routing restarting and recovery after node failure in automatic exchange optical network

The present invention relates to a control method for realizing routing restarting recovery after node fault in automatically switched optical network, in particular to a control method for realizing routing restarting recovery between faulty node and neighboring node. The present invention does not need two times of flooding of the routing to the entire network in restarting process, so as to avoid the network congestion caused by flooding to a certain extent, which can accomplish the routing recovery to network in practical application more rapidly and simply.
