Abstract: Dynamical establishment of dependable connections in WDM mesh networks with traffic grooming capabilities was addressed. A new routing algorithm for shared path protection was proposed. The algorithm proposed establishes link-disjoint primary and backup traffic stream paths between the source-destination node pair and reduces the spare capacity. It provides the same level of protection against single link failure as dedicated path- protection scheme. Moreover it is better than dedicated path-protection scheme in network utilization. Network performance, based on dynamic traffic with different load, was investigated via simulations. The scheme can improve the performance of the network significantly.
