The static tunnel ring network protection configuration used at present, i.e. g.8132 ring network protection, includes: a working tunnel and a protection tunnel for the working tunnel. However, with the increase of traffic, the number of tunnels in the network is increasing, and the defects of difficult maintenance, reduced network performance, slow protection switching speed, and the like occur. The shared ring network protection method is abbreviated as: the sharing ring effectively solves the defects and is widely used by operators. Each network element in the shared ring is configured with a clockwise (east direction) working tunnel and a counterclockwise (west direction) working tunnel, and each working tunnel is correspondingly configured with a protection tunnel. And the working tunnel and the corresponding protection tunnel form a protection sub-network. A tunnel has a label switching instance LSP per network element and a protection sub-network has a protection group per network element.
