A framework of scalable optical metropolitan networks for improving survivability and class of service

Abstract

The issues of scalability and class of service have been among the most important research focuses in design of the control plane for wavelength-routed WDM networks. We introduce a framework for achieving a scalable design in metropolitan area networks with WDM as the core technology (called optical metropolitan networks). The framework is summarized with the topics of survivability, scalability and class of service. A novel design concept, called interarrival planning, which aims to achieve scalable control and management in optical metropolitan networks, is addressed.
