Abstract:Multicast routing and wavelength assignment (MC-RWA) is an important issue when designing multicast WDM ring networks. Two heuristic multicast routing methods, minimum spanning tree (MST) and shortest path routing (SPT), have been studied extensively. However, the comparison of those two heuristics in terms of the number of required wavelengths is still an open issue because of the lack of efficient optimization methods for MC-RWA. In this paper, using a recently developed optimization algorithm, we compare th… Show more
