Abstract

While there are a lot of advances in the area of QoS deployment and management over IP networks, there is still a need for a robust QoS renegotiation framework for multimedia applications. A QoS renegotiation framework has three concurrent modules which should be integrated with the least amount of overhead. These muddles include a feedback mechanism, a load control mechanism, and a service-response mechanism. This thesis proposes a new feedback mechanism which is based on call rejection notification for QoS renegotiation. The difference between the proposed mechanism and previous approaches is that it uses flow information (not packet information) as a feedback mechanism. The new feedback mechanism provides a better QoS, improves the system performance, and maximizes the service revenue.
