| Abstract: | In many cases traffic is aggregated from several sources, or simply has no well‐understood characteristics, and so it is difficult for the user to decide the basis on which bandwidth should be demanded. A strategy is described to determine the optimum way to decide when to renegotiate the traffic capacity provided in ATM and similar systems. The performance of the strategy is evaluated using simulations on traffic with theoretical distributions and also on recorded real traffic. The strategy appears to work and the results give insights into the very limited benefits obtained by increasing the granularity of the rates provided. Copyright © 2001 John Wiley & Sons, Ltd. |
