An important objective of Internet traffic Engineering is to facilitate reliable network operations by providing proper QoS to different services through mechanisms which will enhance network integrity and achieve network survivability. Current Internet architecture is very much distributed in nature interconnected by Internet Service Providers (ISPs), where the central goal of each service provider is to enhance emergent properties of their network by providing better service qualities with strong emphasis on economic considerations. Hence, service providers always aim at setting up their objective function based upon economic considerations and governed by their network wide policies to get the best result. In this paper we present a scheme in which Autonomous System (AS) relationships are central to any policy decision imposed by individual ISPs. Based on these policy relationships, we propose a framework which is expected to match the need for better QoS, uniform Internet wide service management and contribute efficiently towards traffic engineering. This paper presents an integrated approach comprising traffic engineering, routing and policy mechanisms for better management of QoS over the Internet.
