QoS Implementation For MPLS Based Wireless Networks

Abstract: Voice has been the primary application in wireless networks to date. However, packet based applications and higher bandwidth requirements to sustain these applications are ever emerging. As in wireline packet based networks, while IP routing is well understood, IP networking by itself is still not achieved and is dependent on the backbones that can offer quality of service gurantees. Mulitprotocol Label Switching (MPLS) is a newer technology that offers service integration, layer 2 switching and connection orientedness, that allows traffic engineering control traffic flows in the network. The purpose of this paper is to show how MPLS QoS architecture can be employed to provide traffic engineering in broadband wireless networks.
