Admission control is a critical element for supporting Quality-of-Service in networks. We propose and evaluate the performance of an adaptive ingress admission control scheme that is suitable for use in a Differentiated Services Internet backbone. The proposed scheme improves upon the admission control scheme by measuring the maximal arrival rate envelope at an ingress node and adding an adaptive adjustment scheme that dynamically adjusts the perceived network capacity in correlation with the rate at which a specified end-to-end delay bound is violated. Simulation results are presented to show that the proposed adaptive ingress admission control scheme is more effective than the egress admission control scheme.
