Effect of wavelength conversion factor on blocking probability and link utilization in wavelength routed optical network

Abstract

Due to introduction of various wide-band applications in wired and wireless network demand of bandwidth is growing exponential. The existing network is not capable to meet the requirement of vast bandwidth. These requirement can be meet by all optical network which is capable of transmitting enormous data at very high speed, around 50 Tera bits per seconds (Tbps) A wavelength conversion technique is addressed in this paper to reduced the blocking probability in wavelength routed networks. It is seen that the blocking probability of traffic requests decreases as the wavelength conversion factor increases. We explode the possibility for network with different size comprising of 25, 50 and 100 nodes with variation in wavelength per link In this work the effects of varying number of wavelength converters, different traffic types on fiber link utilization and network blocking probability are evaluated and results are shown that the blocking probability is minimum with wavelength conversion factor of 0.5. Thus we propose a network with 32 and 64 wavelengths and 50 % wavelength convertible nodes.
