Abstract

At a buffered switch in an ATM (asynchronous transfer mode) network it is
important to know what combinations of different types of traffic can be
carried simultaneously without risking more than a very small probability of
overflowing the buffer.  We show that a simple and serviceable measure of 
effective bandwidths may be computed for stationary traffic sources.  For
large buffers the effective bandwidth of a source is a function only of its
mean rate, index of dispersion, and the size of the buffer.
