Abstract

The emerging technology of Elastic Optical Network (EON) has appeared to satisfy bandwidth hungry demands of today’s world. Routing and spectrum assignment is a major problem in EON for efficient spectrum utilization. In this paper we proposed a novel routing and spectrum allocation technique which gives efficient spectrum utilization by reducing blocking probability. This approach guarantees spectrum allocation upon arrival of a connection request but there may be some delay. This is called Request Provisioning with Reservation (RPR). The simulation results shows that this technique enhances spectrum utilization and reduces call blocking.
