Trends in Survivability Techniques of Optical Networks

The ability of a network to continue functioning even after the occurrence of any failure is very much required in optical networks. As optical networks are capable of transmitting a large amount of data at very high speed, so any failure or breakdown even for small duration can cause significant data and revenue loss. So the survivability of optical networks has become very important issue for research. Many efforts are going on to improve the survivability of optical networks. Most of the failures occur due to the link failures. Keywords— Network Survivability, Link Failures, Optical Networks
