Differentiated Admission Control in Large Networks

This paper proposes a simple but effective admission control algorithm for integrated services packet networks. The admission control scheme, based on stochastic control, aims at ensuring user discrimination, by enforcing different call blocking probabilities. The queueing behavior of reservations is analytically characterized in the absence of admission control. From this, call blocking probabilities and analytical estimates of the performance of admission control are derived, allowing proper tuning of the algorithm. Simulations illustrate the effectiveness of the algorithm. Keywords—Admission Control. Priority policies. Adaptative Schemes. Large Deviations.
