In this paper, we proposed a fast recovery strategy for a dual link failurein elastic optical network. The elastic optical network is a promising solutionto meet the next generation higher bandwidth demand. The survivability of highspeed network is very crucial. As the network size increases the probability ofthe dual link failure and node failure also increases. Here, we proposed aparallel cross connection backup recovery strategy for dual link failure in thenetwork. Proposed strategy shows lower bandwidth blocking probability (BBP),fast connection recovery, and bandwidth provisioning ratio when compared withthe existing shared path protection (SPP) and dedicated path protection (DPP)approaches. Simulation is performed on ARPANET and COST239 topology networks.
