Abstract :
This paper studies the multicast survivability and proposes a new heuristic algorithm called Enhanced Multicast Hamiltonian Cycle Protection (EMHCP) to tolerate the single link failure in WDM optical networks. For each multicast demand, EMHCP computes a least-cost light-tree based on the presented link-cost function that considers the load balancing and the proper straddling link selection so that the backup wavelengths on the Hamiltonian cycle can be reduced. Simulation results show that, compared to conventional algorithm, EMHCP can obtain significant improvement in resource utilization ratio.
