Abstract
We investigate the problem of grooming dynamic multicast traffic in WDM mesh networks. This problem is equivalent to designing a light-tree based logical topology for multicast streams. To the best of our knowledge, this problem has not been considered before in the literature. The problem consists of four parts: (1) multicast routing sub-problem; (2) multicast wavelength assignment sub-problem; (3) design of a light-tree based logical topology sub-problem; (4) traffic-grooming sub-problem.
