Abstract

Multicast applications have attracted more and more attention due to more efficient bandwidth usage and the increasing popularity of the point-multipoint multimedia applications. Supporting multicast directly at physical layer, namely optical multicasting, can provide improved performance over electronic multicasting. In this paper, a new Mixed Integer Linear Programming algorithm is proposed to resolve the light-tree routing and wavelength assignment problem with wavelength continuity constraints. The node in our system is limited branching and power-efficient multicast capable OXC. The node constraints are considered in our model formulation. Numerical results are given by using representative examples and discussed to show the efficiency of our algorithm.
