Abstract
Asynchronous transfer mode (ATM) networks transport information as 53-byte cells that follow one another from the source to the destination. The different streams of cells (called virtual circuits) share buffers in the switching nodes of the network. Typically, cell streams are bursty. These fluctuations in the streams may lead switch buffers to overflow and, therefore, to lose cells. In this paper, we explain a procedure for estimating the spare capacity of switches in the network. The network can use these estimates to decide whether or not to accept new calls and how to route them. The difficulty that we address is obtaining fast and accurate estimates of the low loss probability. We propose quick estimators based on results from the theory of large deviations.
