An Admission Control Scheme for End-to-End Statistical QoS Provision in IP Networks

This paper presents a distributed andscalable admission control scheme to provide end-to-end statistical QoSguarantees in IP network. The basic idea of the scheme is that theingress routers make admission control decisions according to thenetwork status information obtained by sending probing packets along theselected routing path. Each router passively monitors the arrivingtraffic and marks the probing packets with its network status. Theperformance of the presented scheme is evaluated with a variety oftraffic models, QoS metrics and network topologies. The simulationresults show that the proposed scheme can accurately control theadmissible region and effectively improve the utilization of networkresource.
