Constructing Resource Constrained Multicast Trees on WDM Networks with Limited Light-Splitting

Wen-Lin Yang, Chun-Tao Yang, and Yu-Chung Huang
Abstract—Traditionally, the optimization goal of multicast routing in WDM optical networks is to minimize the number of wavelengths and fibers used for the multicasting. In this paper, we consider a problem concerned about how to multicast several video streams simultaneously to a number of clients in a given WDM network with sparse light spitting, where the number of wavelengths on each link is given in advance. Our goal is to construct a number of multicast trees for all required streams so that the multiple constraints: bandwidth, delay and multicast capability, are satisfied and the total number of clients participating in all multicast sessions is also maximized. This problem is referred as profit-oriented and delay-constrained group multicast routing (PDGRM) problem. Two heuristic algorithms are proposed in this paper for this NP-hard problem. A set of experimental results are also provided to compare the performances of our heuristics with previous methods published in literature.

Index Terms—Group multicasting, light splitting, profit maximization, WDM networks.
