A way of increasing the traffic we can send over these expensive links is to transmit compressed ATM cells. This idea, although it seems very simple, is a new one for ATM and as we show it can signicantly increase the useful bandwidth of a typical ATM network. In this paper the CAC algorithm that can be effectively used in a network which uses this compression scheme is also described and the results that can be achieved when this algorithm is used in a real network are presented. This CAC algorithm is based on Large Deviation Theory: the large deviation rate-function (entropy) of compressed (and thus more bursty) ATM traffic can be estimated from measurements of trffic activity. The entropy can be used to determine the bandwidth requirement of the traffic.http://creativecommons.org/licenses/by/4.0/49-607th International Conference on Intelligence in Services and Networks, ISandN 2000 Papaefstathiou Ioannis Παπαευσταθιου Ιωαννης Springer Verlag
