摘要
A new heuristic algorithm called "Steiner Node Heuristic" (SNH) for solving the Steiner Tree problem in graphs and, consequently, for routing multicast calls in mesh optical WDM Networks, is presented. The new algorithm is used for the development of a new multicast protection technique which, as simulations show, outperforms the existing ones in terms of blocking probability and average cost, for both single-link and single-link/node failure scenarios.
