Design of a novel active queue management (AQM) scheme to support distributed multimedia flows is discussed. An analysis is done for reducing the loss rates of such flows. Most of the existing AQM schemes consider TCP and TCP-friendly flows, which result in unexpected congestion when multimedia flows compete with them. This AQM uses a pushout scheme to support higher priority multimedia flows that normally use UDP. As loss rate is one of the important quality of service (QoS) parameters, this work aims at reduced loss rate for such flows. Simulation results prove the correctness of the solution and indicate reduced loss rates. The notable feature of this work is that it can be easily implemented in the IP routers. Simulation results in ns-2 are presented. The results conform to the analysis
