Endpoint Admission Control for VoIP Networks with Dynamic Routing

Abstract

In this paper, we propose an endpoint measurement based admission control (EMBAC) with dynamic routing, with which is executed in mesh networks. The basic idea of this admission control is, to use probe flows to measure two routes, which are direct route and one of the two-link routes between each VoIP call's originating-terminating node pair at the same time. Based on the probe flow's QoS evaluation, the node decides a route for call. We compare performance of direct routing , basic dynamic routing and advanced dynamic routing by using simulation. It is shown that an advanced dynamic routing with EMBAC works better to minimizing call blocking probability and packet loss rate than direct routing in the network.
