针对RED算法在网络拥塞控制中使得队列波动较大的缺点,提出了一种归一化最小均方(NLMS)算法,并研究了NLMS算法在主动队列管理中的具体实现。仿真实验通过对NLMS算法、RED算法、REM算法、LRC-RED算法性能的比较,表明NLMS算法具有较好的动静态性能,且能够提高队列稳定性,降低丢包率。
RED algorithm for network congestion control causes the shortcomings of the queue fluctuations,a normalized least mean square(NLMS) algorithm was proposed,and the NLMS algorithm in active queue management in the implementation was introduced.The performances of NLMS algorithm,RED algorithm,REM algorithm,and LRC-RED algorithm were compared by simulation experiments.The results show that the NLMS algorithm has good dynamic and static performance,and it can improve the stability of the queue and reduce the packet loss rate.
