Fast Recovery from Link Failure in Software De ned Survivable Network
Guoqiang Yan, Ming Lei, Jieyong Zhang · 2015
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 recovery algorithm has rapid recovery speed and it has low influence for up layer transport protocol.
