A Distributed WDM Routing and Wavelength Assignment Protocol


Simone Cintra Chagas, Eber Huanca Cayo, Jacir Luiz Bordim


Vol. 9  No. 4  pp. 28-35


The main contribution of this work is to propose a distributed on-demand routing and wavelength assignment algorithm for WDM networks. The proposed scheme, termed Distributed Light-path Allocation (DLA), is capable to select routes and establish light-paths via message exchanges without imposing a major overhead on the network. The proposed scheme is able to balance the load in a WDM network. The simulation results show that the proposed solution is comparable with the other algorithms that demands for a much higher computational and message costs.
