Abstract :
Eight specific architectures for asynchronous transfer mode (ATM) switching systems are compared: the Knockout, Sunshine, Lee´s, Tandem Banyan, Shuffleout, and three variations on buffered Benes networks. The differences between switching systems, based on architectural choices rather than details of implementation are discussed. Several broad categories of systems based on high-level architecture choices are considered. Within each category one or more alternatives are reviewed, and an equation for the chip count for each alternative is developed. The equations are used to make plots of chip count for each network over a range of parametric values.<>
