Analysis and optimization of transmission schedules for single-hop WDM networks
1993
Single-hop lightwave networks with stations interconnected using wavelength-division multiplexing are considered. The stations are equipped with tunable transmitters and/or receivers. Coordination between the transmitting and receiving stations is achieved by assuming synchronous control and a predefined, frequency-time oriented schedule which specifies the slots and the wavelengths on which communication between any two pairs of stations is allowed to take place. The authors define and analyze, in terms of throughput, all possible types of schedules in the situation where the number of available wavelengths is equal to the number of stations. The results are valid for the general case, i.e., nonuniform traffic. The optimization of schedules, given the traffic requirements, is considered, and optimization heuristics that give near-optimal results are presented.<
