Paper Abstract

In this paper, the problem of how to provide survivability to multi-domain optical mesh networks is studied. Differing from the survivable research on single-domain networks, the whole network topology is unknown for all the source nodes. According to this point, we propose a novel protection algorithm called Enhanced Local Segment- Shared Protection (ELSSP) based on the simplified virtual topology for dynamic connections in multi-domain optical mesh networks. For the dynamic connections, ELSSP assigns rational link-cost for the virtual link on the virtual topology when calculating the primary path, and provides segment-shared protection in the passing domains of the primary path. Simulation results show the good network performance of ELSSP.
