Abstract
A recently proposed concept for dynamic provisioning of survivable lightpath services, called the protected working capacity envelope (PWCE) is considered from a network capacity design and blocking standpoint. The PWCE concept offers several attractive properties for a next-generation Internet based on “IP over optical” transport in which transport level connections can be independently and rapidly requested and released by service layer nodes. The main advantages of PWCE are simplification of the state databases and signaling involved for protection considerations in such dynamically operating transport networks. This chapter reviews the concept and related background. It then develops and tests models for the design of PWCEs involving the optimized partitioning of installed capacity into a working envelope, for simple and rapid service provisioning, and a separate reserve network which is configured into a set of p-cycles that provides 100% restorability to the envelope.
