In high-capacity optical WDM networks, the failure of a network component such as a fiber link may disconnect many optical lightpaths, leading to severe disruption in network services. Therefore it is imperatively important to provide fast and full protection against any failure in optical WDM networks. The method of pre-configured protection cycles (p-cycles) is very attractive for design of survivable optical networks. So far p-cycle approach has been extensively studied for design of survivable optical networks where traffic demand is static. In this paper, we first briefly describe our recently proposed p-cycle design heuristic and then show how to apply this heuristic to optical networks where traffic demand is dynamically changing. We consider three different strategies to configure dynamic p-cycles for dynamic traffic demands, and compare their performance in terms of blocking probability and computational time.
