Cost reduction for provisioning survivable multicast sessions in WDM mesh networks

The problem of provisioning survivable multicast sessions in WDM mesh networks has been studied in the literature, and several heuristics have been proposed. We in this paper propose a novel and efficient heuristic algorithm, called segment exclusion (SE), to improve existing algorithms in terms of the cost (e.g., resources) used for provisioning a multicast session. Simulations are conducted to verify the effectiveness of SE.
