In this paper, a new Mixed Integer Linear Programming algorithm is proposed to resolve the light-tree routing and wavelength assignment with wavelength continuity constraints. The node in our system is limited branching and power-efficient multicast capable OXC. Numerical results are given and discussed to show the efficiency of our algorithm.
