With the increasing demand for high data transfer rate, the communication is getting new developments. For progressive data transfer at high data rate services, the means of communication has now taken high offering bandwidth architecture such as optical networks. In optical networks the mode of communication is completely an optical medium and data are transferred from various nodes to reach to the destination via optical routers. Though these networks have high bandwidth compatibility they offer heavy traffic congestion due to non-linear traffics resulting in degraded quality services.
