Internet Traffic Control System and Mobile Broadband Communication System in ATM Networks

Abstract

MPLS is an advanced forwarding scheme which allows the network to achieve the benefits provided by traffic engineering techniques. The establishment of an end to end LSP between two IP/MPLS networks inter connected through an ATM backbone is still an open issue. This focuses in an MPLS ATM environment and address problem of provisioning a fast LSP establishment with certain QOS between 2 MPLS sub networks inter connected through an ATM backbone. The PNNI is used in ATM backbone as a routing and signaling protocol. In order to achieve the paper objectives and new PNNI elements are defined and evaluated. Voice has been the primary application in wireless network to date. However packet based application and higher bandwidth requirements to sustain these applications are ever emerging. As in wire line packet based networks while IP routing is well understood IP network by itself is still not achieved and its depart on the backbone that can offer QOS guarantee. MPLS is a newer technology that offer service information layer 2 switching and connection oriented that allows traffic engineering control traffic flows in the network. The purpose of it to show how MPLS QOS Architecture can be employed to provide traffic engineering in broadband wireless network.
