METHOD FOR SHARING PROTECTION OF MESH NETWORK PROTECTION FIELD AND SYSTEM THEREOF

摘要

A method for the sharing protection of the mesh network protection field and system thereof are provided by the present invention. The method includes: a protection ring is preset in the mesh protection field, the path of the protection ring runs through the source/destination nodes of the multiple services in the mesh network protection field, and the protection resources are reserved in the path of the protection ring only; the protection modes used respectively by said multiple services are determined and the corresponding protection groups are configured; the protection paths of all the protection groups are all set in the protection ring, and the protection resources of the protection ring are shared. By the protection mode of that the protection ring in the mesh network is preset and protection paths used by the multiple services of the source/ destination nodes in the protection ring can be shared, the protection resources reserved in the protection ring are shared, and the network resource availability ratio is improved. For the mesh with N nodes, the maximum network availability ratio is (N-1)/(N+1).
