On the performance of an effective bandwidths formula

C. Courcoubetis, G. Fouskas, and R.R. Weber, ITC,14, 201-212, 1994.


At a buffered switch in an ATM (asynchronous transfer mode) network it is
important to know what combination of different types of traffic can be
carried simultaneously without risking more than a very small probability
of overflowing the buffer.  We argue that for many stationary sources an
effective bandwidth is given by a formula involving just the source mean rate,
its index of dispersion and the size of the buffer.  We report computational
experiments that support the practicality of this formula.
