Distributed bandwidth reservation by probing for available bandwidth

For many applications in Internet protocol-based networks a guaranteed quality of service is crucial. A simple and scalable way of achieving this is to use the differentiated services architecture in conjunction with admission control. In this research, we focus on the reservation of bandwidth by routers on the edge of a single network domain with differentiated services support. We evaluate the assumptions made by previous research on probe-based bandwidth reservation. The availability of bandwidth is determined by measuring the throughput a probe flow of a certain rate achieves while the reservation is accomplished by assuming that the throughput this probe flow achieves equals to an amount of reserved bandwidth.
