The effect of traffic prediction on ABR buffer requirement

It has been demonstrated that traffic prediction improves the network efficiency and QoS performance in ATM networks. This was achieved by avoidance and control of congestion. In this paper, the effects of traffic prediction schemes on the available bit rate buffer are studied. It can be seen that under the same network environment and traffic intensity, traffic prediction reduces the buffer size for the ABR service. In particular, the fuzzy logic prediction introduced by Qiu (see Proc. IEEE GLOBECOM´97, p.967-71, 1997, and Proc. IEEE International Conference on Communications (ICC´98), p.1769-73, 1998 performs better than conventional autoregressive prediction.
