Considering the economic and technical aspects of wavelength converters, fullwavelength conversion capability will not be available throughout opticalnetworks in the foreseeable future. In this paper we have used balanced staticwavelength assignment (BSWA) algorithm. It is a technique to improve theperformance of an all-optical network in respect of blocking probability & otherparameters to provide cost effective optical communication system. We carriedout the performance analysis of wavelength-continuous optical burst switchingnetwork-using BSWA for the network topologies namely NSFNET andINTERNET2NET with the initial assumption that there is no wavelength converteror optical buffer in the networks. For simulation we have used a powerful toolMatplanWDM. The performance analysis of burst loss probability v/s traffic loadusing BSWA algorithm shows that its performance is better than other staticwavelength assignment algorithm. We have also explored the performances ofNSFNET and INTERNET2NET networks on the basis of channel utilization,message delay, and the ratio of traffic transferred in single hop to total trafficoffered against percentage of reused wavelength in the network. It has beenobserved that channel utilization becomes the maximum for 40% of reusedwavelengths per fiber and beyond that cost of network unnecessary increases.By the performance analysis of message propagation delay for both networkTopology, it is observed that message propagation delay, is minimum at 40% ofreused wavelength per fiber and it becomes constant beyond that. It is thereforerecommended that reused wavelengths per fiber should not exceed 40 % of thetotal available wavelength so as to yield cost effective solution with optimumperformance.
