A mechanism for admission control of the input traffic to the UMTS backbone network

As the demand for multimedia applications on the Internet grows, it is hoped that UMTS backbones supports different applications with QoS, mainly those that are sensitive to delay and jitter. In this paper, we propose a mechanism that makes the admission control of the ingress edge routers. Such a mechanism provides a differentiated treatment to the traffic of several flows in the network. The results obtained from modeling and simulation show that the proposed mechanism treats the incoming traffic in a differentiated way, offering a certain level of QoS.
