Abstract

In this paper, we describe and investigate the protection design for survivable WDM mesh networks, and propose our heuristic shared-path protection algorithm, called dual-link failures protection (DLFP). We also present a backup resources assignment scheme to completely protect the dual-link failures, and suggest a joint selection method, which consider the integrated performance of resource utilization and protection recovery time, to compute an optimal working and backup path pair. The simulation results show that DLFP can not only perform better than previous three-step algorithm (TSA) for dual-link failures but also determine the appropriate tradeoffs between the resource utilization ratio (or blocking ratio) and the protection recovery time.
