802.11 Mobile Networks Combined to QoS IP Networks

In Internet user's traffic crosses several areas. Increasingly, users are demanding quality of service (QoS) from beginning to end. Therefore, it is necessary to have a global schema of differentiation not only in the areas which make up the network backbone, but also in access networks that are also often bottlenecks. In this paper, we propose a global schema of QoS management Using DiffServ/MPLS backbones and 802.11 wireless access networks. We provide an evaluation of several scenarios for combining QoS IP networks with 802.11 access network. We conclude with a study on interoperability between QoS patterns in access and backbone networks.
