Paper Abstract

This paper analyzes the connection availability of a protection paradigm, termed permanent dedicated path protection (PDPP), in WDM mesh networks. Numerical results on COST239 European network show that P-DPP reduces the average connection unavailability compared with the traditional dedicated path protection (DPP) at the cost of higher capacity utilization.
