A technique for discovering and identifying locations at which to deploy new Layer-2 nodes within a telecommunications network. The disclosed technique is intended to identify Layer-2 nodes at locations where they can improve service availability when deployed, especially in geographic regions that suffer frequent or simultaneous cable breaks, or both. The locations of the new Layer-2 nodes depend on the underlying Layer-0 network topology, as well as on the existing Layer-2 topology. Thus, the disclosed technique features a cross-layer approach that takes these factors into account and evaluates the locations in a way that can considerably increase the availability of one or more services offered in the telecommunications network.

A method for routing data in a network including a plurality of nodes connected by links, the method includes collapsing first and second rings of the nodes together, for each of the nodes in the network, determining a shortest path tree to each of the other nodes in the network, and for data sourced from a particular one of the nodes in the network, blocking the link or links not included in the shortest path tree determined for the particular one of the nodes. Also, a system for routing data through a network having a plurality of nodes connected by links, includes a ring collapsing module for collapsing first and second rings of the nodes together, a shortest path tree calculation module for determining, for each of the nodes, a shortest path tree to each of the other nodes in the network, and a link blocking module for blocking the link or links not included in the shortest path tree determined for data sourced from a particular one of the nodes.
