An Improving Enhanced Dynamic RIO Algorithm for DiffServ

One of the more pop research issues in the context of Assured Forwarding(AF) is the fair distribution of bandwidth among aggregates sharing the same AF class.Marking algorithm and queue manager are very important for aggregates fairness.An improving enhanced dynamic RIO(EDRIO) algorithm from queue manager was proposed.The paper could not only analyze the fairness according to every packet's size under the homology of aggregates,but also study the fairness of heterogeneous flows in the case of every aggregate with a different bandwidth.The performances of the algorithm were simulated from packet size,target rate and the number of flows in aggregate.The several simulation experiments show that EDRIO is better than RIO for Assured Service in DiffServ networks and Dynamic RIO for Assured Service in DiffServ networks under the homology of aggregates and heterogeneous flows.The this algorithm has a better scalability.
