Abstract

This paper presents a distributed and scalable admission control scheme to provide end-to-end statistical QoS guarantees in Differentiated Services (DiffServ) networks. The basic idea of the scheme is that the ingress routers make admission decisions according to the network status information obtained by sending probing packets from the ingress to the egress of the network. Each router passively monitors the arriving traffic and marks the probing packets with its network status. The performance of our 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 region and effectively improve the utilization of network resource.
