摘要：A method for implementing permanent ring network protection in an MESHnetwork, the method includes the following steps: a node in a ring network protectiongroup informing, when detecting a certain span fails, other nodes in the ring networkprotection group of the failure information (11); each node in the ring network protectiongroup switching a service that is affected by the failure to a protection path thereof fortransmission (12); searching for a substitute path for the failed span in idle resources ofthe MESH network (13); establishing a new ring network protection group by using thesubstitute path and sections that are not affected by the failure in the ring networkprotection group (14); and switching the service that is affected by the failure from beingtransmitted via the protection path to being transmitted via the substitute path (15). Thepresent invention is capable of providing the permanent ring network protection functionfor all the services on the ring network.
