摘要：The problem of routing and wavelength assignment (RWA) is critically important for increasing theefficiency of wavelength-routed all optical networking. So performance analysis of RWA algorithm is required for differenttopologies so that we use topologies for specific application example: (two way video communications). To increase thelink utilizations and to reduce call blockage, the topology comparison is important. Topologies used in this paper forchecking the performance of RWA are random, ring, star, and tree. In this paper we used First-fit algorithm for assigningwavelength and Dijkstra’srouting algorithm for shortest path for different topologies. It is shown that, under dynamicarising of calls the star topology performs the best on blocking probability, and also call blocking ratio (CBR) is 7% andCPU time 0.5sec.Comparative analysis has been done for different topologies. Performance analysis has been done byconsidering various topologies for a dedicated network.
