All-optical networks with wavelength division multiplexing and wavelength-routing offer an excellent application environment for multicast applications such as video-conferencing, high-definition TV (HTDV), distributed simulation and content distribution in mirror sites and in Storage Area Networks, that can operate entirely in the optical domain. Accordingly, native multicast support in next generation all-optical networks is an extremely challenging topic. In this paper we focus on the efficient construction of light-forests under optical-layer power budget and wavelength continuity constraints. We introduced a novel heuristic to improve network utilization in multicast RWA, aiming at addressing the problem of reducing blocking probability for multicast group when building multiple light-trees in a light-forest. In brief, we extended to the multicast environment the idea of minimum interference, well known in bandwidth routing research and avoided any links if they minimize the maximum flow available for future groups. We also studied the performance of the proposed heuristic by conducting simulation experiments which demonstrated its efficiency.
