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.
