Abstract
Abstracf— We consider single-hop Iightwave networks with stations interconnected using wave division multiplexing. The stations are equipped with tunable transmitters and/or receivers. A predefine, wavelength-time oriented schedule specifies the slo@ and the wavelengths on which communication between any two pairs of stations is allowed to take place. We define a wide variety of schedules and develop a general framework for analyzing their throughput performance for any number of available wavelengths, any tunability characteristics, and general (potentially nonuniform) traffic patterns. We then consider the optimization of schedules given the traffic requirements and present optimization heuristics that give near-optimal results. We also investigate how the number of available wavelengths (channels) affects the system throughput, and we develop techniques to efficiently share the available channels among the network stations. As a result, we obtain systems that are easy to scale while having very good performance.Keywords
