Abstract: The routing problem for shared path protection in multidomain optical mesh networks is more difficult than that in single-domain mesh networks due to the lack of complete and global knowledge of the network topology and bandwidth allocation. To overcome this difficulty, we propose an aggregated network modeling by underestimation with a two-step routing strategy. In the first step, a rough routing solution is sketched in a virtual network that is the topology aggregation of the multidomain network. A complete routing is then determined by solvi...
