This paper presents a distributed and scalable admission control scheme to provideend-to-end statistical QoS guarantees in IP network. The basic idea of the scheme is that the ingressrouters make admission control decisions according to the network status information obtained bysending probing packets along the selected routing path. Each router passively monitors thearriving traffic and marks the probing packets with its network status. The performance of thepresented scheme is evaluated with a variety of traffic models, QoS metrics and network topologies.The simulation results show that the proposed scheme can accurately control the admissible regionand effectively improve the utilization of network resource.
