It is seen that the blocking probability of traffic requests decreases as the wavelength conversion factor increases. In this paper investigation are carried out to manage the traffic load by reducing the blocking probability and we explore the possibility for network with different architecture comprising of 25 and 100 nodes with wavelength per link as 16, 64, respectively. In this work the effects of varying- traffic load, number of wavelength converters, different traffic types, data rate on fiber link utilization and network blocking probability are evaluated and the investigation shows that the blocking probability is minimum with wavelength conversion factor of 0.5, However, it is not useful to use more than 60% wavelength convertible nodes because the performance is almost equal. Performance of all optical network with reference to other parameters, such as Link utilization, Avg. packet delay have also been explored. The performance analysis shows that for a randomly generated network comprising of 100 nodes, the no. of wavelengths = 32 and with 60% wavelength convertible factor, is most suitable to give overall good performance.
