The Dual-Banyan (DB) switch: a high-performance buffered-Banyan ATM switch

Multistage interconnection networks (MINs) are very popular in ATM switching since they can achieve high-performance switching and are easy to implement and expand due to their modular design. In this paper we present and describe in detail a high-performance buffered-Banyan switch which encompasses multiple input-queueing as its buffering strategy. We call this switching architecture Dual-Banyan switch. Simulation results are given to demonstrate its throughput, mean waiting time and cell-loss performance considering different switch and buffer sizes. We further compare it to the simple, single-queue buffered Banyan network, assuming, for reasons of fairness, the same total buffer capacity with respect to uniform and non-uniform traffic patterns
