Path-based protection in WDM mesh networks subject to double-link failures ?
This letter studies the protection problem in WDM mesh networks and proposes a new scheme called improved path-based shared protection (IPSP) to tolerate double-link failures. Differing from previous path-based shared protection (PSP), IPSP allows some primary and backup paths to share resources. Simulation results show that IPSP outperforms PSP.
