摘要：An alternate routing can improve the blocking performance of an optical network by providing multiple possible paths between source and destination nodes. Wavelength conversion can also improve the blocking performance of an optical network by allowing a connection to use different wavelengths along its route. But wavelength conversion scheme is not an economical proposition. We perform simultaneous study of the relationship between traditional alternate routing scheme and fuzzy logic based alternate routing scheme for comparative studies of those two schemes. Connection set up time and blocking rate reduction are the two important parameters of any optical data communication networks. These two parameters are computed in the present work. It is observed that fuzzy logic based alternate routing scheme provides better performance by reducing the connection set up time and blocking rate in optical network. The effect of the variation of number of wavelengths is also studied to see their effects on connection set up time and blocking rate.
