Dynamic routing with endpoint admission control for V61P networks
Xiang T.R. Kong, K. Mase · 2004
In this paper, we propose a dynamic routing with endpoint measurement based admission control (EMBAC) for VoIP networks with mesh topology. 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. Based on the probe flow's QoS evaluation, the node decides a route for each 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 for minimizing call blocking probability and packet loss rate than direct routing.
