Abstract

Multicast protection strategies have been widely explored in current literature. However, the leaf availability requirements are not taken into account. In this paper, we investigated approaches and algorithms for establishing a multicast session with differentiated leaf availability requirements in WDM mesh network while protecting it against single link failure. An effcient and cost-effective heuristic is presented to solve the problem and is compared with two other schemes, one with no protection (Scheme I) and the other with dedicated protection (Scheme II). We also formulated a possible improvement of the proposed algorithm. Simulation results based on 14 node NSFNET topology and comparisons among these schemes are also discussed. The performance of an algorithm is measured in terms of Average Cost and Average Satisfaction Ratio. The improved algorithm shows much better performance than the other ones, thus achieving the goal of effectively establishing protected multicast sessions with differentiated destination availability requirements. Finally, through numerical simulation results, we find that some links are critical to the performance of the network. Increasing the availability and capacity of these links will greatly enhance the network performance. This result is helpful to network planning and design.
