This paper addresses the modelling and evaluation of cell scheduling policies in ATM multiplexers using stochastic Petri nets. In particular, we compare four cell scheduling policies: a FIFO policy with and without non-preemptive priorities, a threshold priority policy as recently proposed by Lee and Sengupta, and an extension thereof. The aim of this paper(More)
We address the performance, in particular, the cell loss ratio, of the ATM GAUSS switch under a variety of realistic video and constant bit rate traac patterns. We describe the operation of the GAUSS switch and derive a stochastic Petri net model for it. One problem with this model, when subjected to realistic traac, is that it is too large (in terms of(More)
