In future high-capacity wavelength division multiplexed (WDM) optical networks, the failure of a network component such as a fiber link can lead to the failure of all lightpaths that traverse the failed link. Since each lightpath is expected to operate at a rate of several Gbps, such a failure can lead to a severe disruption in the network's traffic. So it is critically important to design WDM optical networks that are inherently fault-tolerant against events such as fiber cable cuts, central office failures and hardware failures. A survivable WDM optical network can provide alternate routes between a pair of nodes in case of failures. The primary objective of network survivability is to maintain the end-to-end data service in the event of any network element failures such as link or node failures.
