Abstract

Future WDM optical networks are foreseen to be more dynamic and sensitive to failures. Therefore, dynamic service provisioning with network survivability becomes a critical requirement for network planning and management. The concept of protected working capacity envelope (PWCE) is attractive because it does not need protection resources to be dynamically configured thereby simplifying network management and reducing processing overheads. In this paper, we consider a p-Cycle-based Strategy for adaptive PWCE (protected working capacity envelope) design where PWCE can adaptively change with dynamically changing traffic. The blocking performance of this new strategy is compared to that of p-Cycle-based PWCE under a dynamic and non-uniform traffic model. The results show that the new strategy can adapt well to dynamic traffic demands that are non-uniform among the network nodes.
