In survivable optical networks, wavelength assignment is a major concern than assigning routes to the light path requests. Earlier wavelength assignment algorithm suffers from unbalanced utilization of wavelengths that leads to blocking probability for any connection request. This paper analyzes the performance of the wavelength assignment strategies to reduce the network block rate of the request considerably. Simulation results indicate that the round robin assignment algorithm achieves reduced network block rate and delay with increased bandwidth utilization and throughput.
