In this paper, we proposed an IP Local Link-Protection (IPLLP) scheme based on the characteristic of shortest-path routing in IP networks. Our scheme working in an intra-area routing domain provides a simple and efficient solution to improve IP network survivability without extra control protocols and enhanced routing protocols. Because the backup next hops are predetermined in advance, the service interrupted time can be limited to a few milliseconds. In the simulation results, we observe that IP Local Link-Protection scheme can efficiently improve network survivability in a small-scale and high-degree network.
