%X Network coding method can effectively improve the protection efficiency of path protection. Many proposed protection schemes based on network coding demand the working paths are link-disjoint. The demand limits the performance and applied range of protection scheme. A new network coding path protection scheme of shared-link(SNCPP)is proposed to resolve the share-link problem in the paper. The scheme adds the two end-nodes of shared link into source and destination node set of the protection path. The shortest protection path that goes through all the nodes of the node set is got by the improved ASTAR algorithm. The paths with shared-link are protected by network coding. The simulation results show that the scheme can protect the network when the shared link fails, and improve the efficiency of protection.
