Abstract

Routing and wavelength assignment has become a critical in all optical networks as on the basis of it the network performance is estimated. We can work upon the various network parameters like blocking probability, throughput, and error rate by choosing the optimal routing and wavelength assignment methods. In this proposed work we are proposing the dynamic adaptive shortest path routing algorithm which chooses the best possible light path between the source &destination pair. Furthermore routing algorithm and wavelength assignment technique can be used to evaluate the blocking probability, error rate, throughput and the routing overhead of EONNET, INTERNET2NET, NFSNET and SIMPLENET4 network topologies.
