Abstract

The authors consider a discrete-time model of an access ATM switch with output buffers. A switch with output queueing has an optimum performance; however, it requires a switch fabric with speed N. However, the switch fabric may operate at L<N times the speed of the input/output links. The random traffic assumption underestimates the buffer size. Each input port of the switch is assumed to be driven by an interrupted Bernoulli process and every cell in a burst is directed to the same output port. An efficient aggregation method is applied for the performance analysis of the switch. The results prove to be very good
