This paper proposes a buffer management scheme called BRED (Buffer and Rate Estimate Division). Our primary goals are to support fairness among various contending flows, and reduce the packet processing work. Basically, it divides the flow rates into classes and each class is assigned a buffer partition along with dropping and hopping policies. These policies control misbehaving flows and enhance buffer usage. The efficiency of our algorithm is evaluated extensively through simulations. The results prove that our algorithm performs convincingly good in most cases, and compromises well between fairness and simplicity.
