Metropolitan area packet-switched WDM networks: A survey on ring systems

Martin Herzog, Martin Maier, Martin Reisslein
2004 IEEE Communications Surveys and Tutorials  
We provide a comprehensive survey of packet-switched ring metro WDM networks. We first review current standardization and testbed activities, then we provide a categorization of ring WDM networks.We structure our survey according to a classification of the medium access control (MAC) protocols employed in the networks. Throughout the article we pay close attention to the key factors that govern the throughput-delay performance of the networks, such as the source vs. destination stripping of the
