Fair bandwidth allocation for responsive and unresponsive flows using approximate fairness dropping scheme

In this paper, based on Equivalent Active Flow, we propose a novel technique called Approximate Fairness Dropping, which is able to achieve approximate fairness by containing misbehaved flows' access queue opportunity with low time/space complexity. Unlike most of the existing Active Queue Management schemes (e.g., RED, BLUE, CHOKE), Approximate Fairness Dropping does not drop the packets whose arriving rate is within the maximum admitted rate, so it protects the well-behaved flows against misbehaved ones, moreover, improves the throughput and decreases the queuing delay Our simulation and analysis demonstrate that this new technique outperforms the existing schemes and closely approximates the "ideal" case, where full state information is needed.
