A DECISION-THEORETIC APPROACH TO CALL ADMISSION CONTROL IN ATM NETWORKS

This paper describes a simple and robust ATM call admission control, a nd develops the theoretical background for its analysis. Acceptance de cisions are based on whether the current load is less than a precalcul ated threshold, and Bayesian decision theory provides the framework fo r the choice of thresholds. This methodology allows an explicit treatm ent of the trade-off 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 model assumptions, its p erformance relative to a control possessing precise knowledge of all u nknown parameters, the relationship between leaky bucket depths and bu ffer requirements, and the treatment of multiple call types.
