The tradeoff between the number of deployed p-cycles and the survivability to dual fiber duct failures

p-Cycles can attain high capacity efficiency and fast protection switching times in WDM networks. The number of deployed p-cycles and the ability to survive dual fiber duct failures are further important characteristics which are considered in a pan-European network case study. We show that the dual failure restorability and the protection capacity can vary significantly for cycle-configurations with different numbers of deployed p-cycles.
