A New Path Protection Algorithm for Meshed Survivable Wavelength-Division-Multiplexing Networks

In this paper, we investigate the relationship between the resource sharing degree and the protection ability, and propose a new path protection algorithm (PPA) to protect the multi-link failures in survivable wavelength-division-multiplexing (WDM) mesh networks. Under dynamic traffic with different load, the simulation results show that PPA not only provide 100% protection for the single-link failure but also has higher resource utilization ratio than the dedicated-path protection (DPP) and higher protection ability than the shared-path protection (SPP) as the multi-link failures occur. With configuring different parameter, PPA can determine the appropriate tradeoffs between the resource utilization ratio and the protection ability.
