Paper Abstract

In recent past we have witnessed the migration of the Internet from a classic computer communication infrastructure to a platform for multimedia applications. Several new approaches have appeared and many protocols have been presented in order to accomplish this transformation. However many challenges remain, especially in the provision of quality of service (QoS). We present and evaluate new techniques and combinations of other well-known QoS mechanism to achieve end-to-end QoS for real-time applications. We propose a priority disciplines for Differential Services architectures and evaluate it in detail for mixed traffic including streams that use conventional protocols such as UDP or TCP and others that are targeted for real-time applications such as RTP. Next we present new brokering concepts at the boundary of the DS-Domain. We present two new dynamic Service Level Agreement methods that will help us accomplish our end-to-end delay minimization goal. These new approaches reduce the connection and/or re-connection time expended by the server during the agreement process with the DS-entry nodes. Finally we include a QoS routing mechanism in our system and map its features to the DS-domain characteristics
