As the Internet becomes increasingly important to all aspects of society, it is critical to increase the survivability of the networks. A fast recovery algorithm was proposed by employing a centralized survivable controller to detect and recovery from link failures. A greedy strategy was used by relaying the separated link from a replaced path to improve recovery speed. The proposed algorithm is also adapted to node or area failures. Simulation experiments were conducted and showed that fast
