A Novel Segment-Shared Protection Algorithm in Multi-domain Optical Mesh Networks

摘要：

In this paper, we propose a novel segment-shared protection algorithm (SSPA) for multi-domain optical mesh networks. In SSPA, intra-domain links and inter-domain links are protected with segment-backup paths respectively. The segment-working path is protected with path shared protection in single-domain and the inter-domain link is protected with shared segment-backup path that it could traverse several domains. The major advantage of SSPA is its shorter recovery time than previous path protection in multi-domain optical mesh networks. The SSPA resolves the inter-domain link protection problem successfully. The computer simulation results show that resources utilization ratio of our proposed SSPA is near to the optimization algorithm that requires the global knowledge of network topology.
