Abstract

This article proposes a new heuristic algorithm, called Shared Multi-sub-backup-paths Reprovisioning (SMR), to improve the survivability for multi-link failures in WDM mesh networks. In SMR, each connection will be initially assigned one primary path, one backup path, and multiple sub-backup paths. When failures occur, based on the corresponding policy SMR will reprovision the primary or backup resources for these connections affected by the failures. Compared to previous algorithms, the survivable performance of SMR can be significantly improved.
