Abstract
Dual-Banyan (DB) is a buffered banyan asynchronous transfer mode (ATM) switch encompassing multiple input-queueing (bifurcated queueing) as its buffering strategy. This paper describes a new analytical model for a performance evaluation of the DB switch under arbitrary traffic patterns. The model developed and presented enables the computation of the switch normalized throughput and the average packet delay by iterative calculations. The efficiency of the given model is verified through a comparison with simulation results, too. We compare throughputs of DB switch and input buffer banyan, and show that DB switch has significantly better performance levels. Copyright © 2003 AEI.
