Abstract
A new analytical model of the finite cross­point
buffered multistage ATM switch under uniform and
nonuniform traffic patterns is developed in this paper.
Three scheduling policies for selecting a cell to be trans­
mitted are compared. We have studied the impact of hot
spot traffic on the performance of the switch. The ef­
fect of cross­point buffering and output buffering on the
performance of the switch is also reported. The results
from the model were validated with simulation results.
It has been shown that the model provides very accurate
results.

The asynchronous transfer mode (ATM) has been ac­
cepted as the transport mechanism in future broadband
