Implementation of new technique for the capacity improvement in wavelength division multiplexing networks

Abstract

In WDM network, the multicast routing and wavelength assignment (MC-RWA) problem is for maximizing the number of multicast groups admitted or for minimizing the call blocking probability. In this technique, the incoming traffic is sent from the multicast source to a set of intermediate junction nodes and then, from the junction nodes to the final destinations. Then, paths from source node to each of the destination nodes and the potential paths are divided into fragments by the junction nodes and these junction nodes have the wavelength conversion capability. By simulation results, it is proved that the proposed technique achieves higher throughput and bandwidth utilization with reduced delay. © 2013 Springer Science+Business Media New York.
