- Title
Accurate modelling of the queueing behaviour of shared buffer ATM switches.

- Abstract
A model for the analysis of multistage switches based on shared buffer switching for Asynchronous Transfer Mode (ATM) networks is developed, and the results are compared with the simulation. Switches constructed from shared buffer switches do not suffer from the head of line blocking which is the common problem in simple input buffering. The analysis models the state of the entire switch and extends the model introduced by Turner to global flow control with backpressure mechanism. It is shown that buffer utilization is better and throughput improves significantly compared with the same switch using local flow control policy. Copyright © 1999 John Wiley & Sons, Ltd.
