Restoration speed is so slow with current restoration mechanisms that it can not meet the needs of some services in WDM mesh networks, p-Cycles(preconfigured cycles)established with spare capacity can attain ring-like speed and mesh-like capacity efficiency. It can be applied to various networks such as WDM networks and IP networks with simple operations and flexible methods. This paper introduces its fundamental configuration process and optimization discusses the multi-failure case and evaluates some new viewpoints.
