摘要 为了避免RED缺陷,提出一种改进的RED算法——RED-r。该算法采用二次圆函数来计算丢包概率,减少了RED的设置参数,实现了在网络大延时和小延时时的队列稳定,且在小延时能获得比PID队列更平滑的效果。NS2仿真验证了RED-r算法的有效性。 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.
