Paper Abstract

Seven common interconnection architectures are evaluated for use as guided-wave interconnection networks. Comparisons are based on characteristics such as the number of switching elements, number of stages or path length, number of layers, number of waveguide crossings, connectivity and routing algorithms. Investigation of the active splitter/active combiner, passive splitter/active combiner, crossbar, n-stage, buddy type multistage interconnection network (MIN), duobanyan and Benes architectures reveals a trade space which is both complicated and previously not well explored. Even among the topologically equivalent MINs such as the baseline, reverse baseline, regular SW banyan with S equals F equals 2, indirect binary n-cube, modified data manipulator, omega or flip networks, the number of waveguide crossings varies while other properties remain constant. Analysis of this larger set of factors reveals more complex trade offs, and presents these architectures in a new perspective.
