✦ Synopsis

Asynchronous transfer mode (ATM) switches can be constructed by connecting multiple banyan networks in parallel. To utilize the capacity of the parallel banyan networks fully, it is crucial to allow up to L cells from each input to be switched, and up to L cells to be received by each output simultaneously, where L is the total number of parallel banyan networks. This is possible if the switch operates in L overlapping phases and one banyan network is used to switch cells in each phase. Although a couple of such designs have been proposed and simulated, there is a lack of suitable models for such switches to be analysed mathematically. In this paper, two approximate analyses of a parallel banyan ATM switch are described. A comparison of the analytical and simulation results show that the analyses give reasonably accurate results.
