A decision-theoretic approach to call admission control in ATM networks

R. J. Gibbens, F. P. Kelly, and P. B. Key

Abstract

This paper describes a simple and robust ATM call admission control, and develops the theoretical background for its analysis. Acceptance decisions are based on whether the current load is less than a precalculated threshold, and Bayesian decision theory provides the framework for the choice of thresholds. This methodology allows an explicit treatment of the trade-offs between cell loss and call rejection, and of the consequences of estimation error. Further topics discussed include the robustness of the control to departures from the model assumptions, its performance relative to a control possessing precise knowledge of all unknown parameters, the relationship between leaky bucket depths and buffer requirements, and the treatment of multiple call types.
