Performance analysis of ATM switches under a multi mode traffic model

Abstract

We present a new performance analysis method for input and output queueing switches, driven by imbalanced traffic processes, using a correlated G/G/1 queueing model. We construct a correlated G/G/1 queueing system to characterize the queueing behavior of the underlying switch. For this system, "messages" correspond to input traffic "modes". We derive the cell delay distribution and the cell blocking probability for the switch architectures under consideration. We also state stability conditions for the message processes served by the switches under consideration. For cell arrival processes which are deterministic within each mode, the analysis is exact.
