# Stochastic analysis of intelligent switching

### R.R. Weber. *BT Technology Journal,* 12, 63-66, 1994

At a buffered switch in a asynchronous transfer mode network
it is important to know what combinations of different classes of
traffic can be carried simultaneously without risking more than a
very small proportion of cells being lost by overflows of the
buffer. The paper explains an algorithm for estimating the cell
loss rate from a special on-line simulation and also how
effective bandwidths may be computer for certain 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.
