Abstract: This paper presents a new Routing and Wavelength Assignment (RWA) strategy for WDM Optical Networks. This new strategy is based on a maximum flow computation and it is particularly useful when we consider optical networks with limited wavelength conversion capability. We use a simple topology transformation combined with a flow-network representation to solve the RWA problem without decoupling Routing from Wavelength Assignment. Results and comparisons show that the max-flow based RWA strategy outperforms, in terms of blocking probability, other state-of-the-art strategies. External Link.
