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