An efficient end-to-end measurement based admission control for VoIP networks

We argue the end-to-end measurement based admission control (EMBAC) in VoIP networks. We present a new probability-based EMBAC scheme and show that its performance is close to the ideal method using virtual trunk-based admission control. We then present a QoS allocation approach and the highest load link-based method for selecting an admission threshold and dimensioning link capacities. It is shown that the QoS allocation approach guarantees the end-to-end target in terms of blocking probability and average packet loss rate and the highest load link-based method is cost-effective.
