Performance Analysis on Various Wavelength Assignment Algorithms with Traffic Grooming

Wavelength Division Multiplexed switching networks are important for the future transport networks. This paper analyzes the performance of various wavelength assignment algorithm and their effect on the blocking probability of the connection request in the optical network with traffic grooming. The wavelength assignment is a unique feature in wavelength routed network that distinguish them from the conventional networks. The wavelength assignment algorithms are classified as First fit, Random fit, Most used, Least used and wavelength conversion algorithms. Simulation is done for the 16 node optical ring network. The experimentation results indicate that the most used algorithm achieves reduced network blocking rate with and without traffic grooming.
