On the effective bandwidth in buffer design for the multi-server channels

Gibbens and Hunt [3] derive the expression for the effective bandwidths for a uniform arrival and service model of traffic flow offered to a multi-service channel. Their model is based on negative exponentially distributed on-times of the traffic sources. The present study leads to the expression for the effective bandwidth without specifying these distributions explicitly. By the results so obtained the influence of the burstiness of the individual source traffic on its effective bandwidth can be analysed; it is shown that it can be quite substantial.
