Abstract

We have proposed and evaluated a novel heuristic algorithm of routing and wavelength assignment (RWA) for scheduled lightpath demands (SLD). Our algorithm is shown here to have a performance gain in terms of the number of wavelengths up to 65.8% compared with the most recently introduced method, TDP_RWA, and works on directed and undirected optical networks. Also, we show the execution time of our proposed method is feasible.
