Abstract

Multicast routing and wavelength assignment MCRWA 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 MCRWA In this paper using a recently developed optimization algorithm we compare the two multicast routing methods and optimal MCRWA The results show that SPT requires about 1–12 more wavelengths than MST Moreover the number of required wavelengths under MST routing is shown to be very close to that of the optimal solution
