On the Reduction of Congestion for Multimedia Streaming in Diffserv Networks

In this paper, we propose a simple meter and classification scheme, specifically designed for real-time multimedia streaming applications in Diffserv QoS networks. This is based upon the observation that conformance deterioration takes place on such networks for all traffic of variable-size packets. We show that it is simple to detect, shape and drop packets which experience exceeding delay, thus reducing the incurring congestion and providing better network resource utilization.
