Abstract

This paper studies the wavelength assignment algorithm in WDM networks. On the basis of discussing the difference between two typical wavelength allocation policies (Complete Sharing policy and Complete Partitioning policy), the dynamic threshold is introduced to solve the restrictions of the Complete Partitioning policy. Then a novel wavelength assignment algorithm based on the dynamic threshold is proposed. Besides, the constraints of dividing the wavelength set into separate subsets are given as well as a series of dynamic threshold values. In the network simulation, the NSF net is chosen as the network model. Two kinds of wavelength assignment algorithms with and without adopting the dynamic threshold are compared. The numerical results show that both the blocking probability and fairness improve by adopting the dynamic threshold.
