A method and system for sharing protection of a mesh network protection domain are disclosed by the present invention. The method includes: presetting a protection ring in the mesh network protection domain, a path of the protection ring running through source and destination nodes of a plurality of services in the mesh network protection domain, and only reserving protection resources on the path of the protection ring; determining protection methods used respectively by a plurality of services said above and configuring a corresponding protection group; setting protection paths of all protection groups on the protection ring, and sharing the protection resources of the protection ring. In the present invention, by presetting the protection ring in the mesh network, each service of which the source and destination nodes are on the protection ring uses the protection method of which the protection path can be shared, and the protection resources reserved on the protection ring are shared, and the network resource utilization rate is improved. For the mesh network with N nodes, the maximum network utilization rate is (N-1)/(N+1). |
