The development of different Internet-based applications requires huge raw bandwidth and proper network management. Optical fiber along with all-optical Wavelength Division Multiplexing (WDM) network is one of the best possible solutions to overcome the bandwidth related issues. The performance of any network is heavily influenced by the choice of the proper network topology. In this paper, a comparative performance analysis between star- and mesh-based optical WDM networks is reported. The required mathematical model is developed to determine the blocking probabilities versus incoming traffic load of the said network topologies for different network parameters. Blocking probabilities of the networks are calculated for various channel capacities and different number of generated calls. The investigation further extended for the node with slow processing speed but having the same traffic load. The performance analysis has been repeated for different data processing speeds. Result shows that the mesh-based optical WDM network provides better blocking probability performance for both slow and fast networks.
