Low Pass Filter / Over Drop Avoidance ( LPF / ODA ) : An algorithm to improve the performance of RED gateways

The Low Pass Filter (LPF) model used to calculate the average queue length in the original RED results in a poor time response, low throughput, and high delay. We proposed a new algorithm, called Low Pass Filter/Over Drop Avoidance (LPF/ODA), to improve the performance of RED gateways. Simulation results have shown that our LPF/ODA algorithm significantly improves the time response of RED gateways, and also results in improved throughput and delay.
