An Architecture and Admission Control Algorithm for Multi-Precedence Voice Over IP (VOIP) Calls
31 October 2004
In this paper, we introduce a novel QoS architecture and a measurement-based call admission control algorithm that supports Quality of Service for multiple voice classes. The algorithm uses link utilization measurements to derive call blocking decisions. The performance modeling results suggest that our proposed solution can limit the packet loss ratio, and hence guarantee voice QoS, even during major traffic overloads.
