New revised queue management algorithm of RED: RED-r
改进的RED队列管理算法：RED-r

In order to avoid the flaws of RED, this paper presented a new revised RED algorithm named RED-r. It used the quadratic round function to calculate the probability of dropping packets, then reduced the amount of RED parameters, the queue remained stable in great or small delay network, and achieved a more smooth effect with small delay than the PID queue. The NS2 simulations validate the effectiveness of the RED-r algorithm.
