摘要：

This letter proposes a novel dynamic shared protection algorithm called Multiple Sub-Backup Paths (MSBP) to survive multiple links failures in WDM optical networks. In MSBP, each connection will be first assigned one primary path and one link-disjoint backup path, and following will be assigned multiple sub-backup paths based on the corresponding routing policy. Compared to previous algorithm DLFP, MSBP not only has the close protection ability to the DLFP but also can save significant resources.
