Abstract: In the last few years, internet traffic increases continuously due to the more use of live streaming and social sites. To accommodate such high traffic demand the more bandwidth is required. The elastic optical network (EON) is a promising solution for the capacity expansion that can meet the future bandwidth requirement. The EON can provide a higher bit rate. In this paper we purposed a recovery strategy for failure in EON. Our purposed strategy shows the more acceptance rate for randomly generated source (s)-destination (d) requests. Here we considered two topologies viz. COST239 and NSFNET. Then evaluate their performance for Recovery Time, bandwidth blocking probability (BBP) and network capacity utilization (NCU), in which our purposed scheme provides lesser BBP and lower NCU for both topologies and low recovery time than shared path protection (SPP and dedicated path protection (DPP).
