A New QoS Renegotiation Mechanism for Multimedia Applications

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. A QoS renegotiation framework has three concurrent modules need to be integrated with the least amount of overhead. These modules include a feedback mechanism, a load control mechanism, and a service-response mechanism. This paper proposes a new feedback approach based on call rejection notification for QoS renegotiation. The proposed approach provides better QoS parameters, improves the system performance, and maximizes the service revenue.
