Abstract: 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...
