Admission control for real-time packet sessions

Admission control is a tool in the management of the grade of service provided by the network to ongoing connections and new sessions. When the admission decision is based on the clipping loss, the authors model the node load by a Markov modulated point process and show that, if the two conjectures introduced hold, the optimum admission control that guarantees quality for all sessions in the node is of a threshold type. If the conjectures fail to hold, then the result holds for Poisson arrivals. The authors characterize the threshold and show that for the admission decision, the admission controller needs to compare the arrival rate matrices to the threshold. This threshold is based on the partial order on the lattice of arrival rate matrices
