针对网络拥塞现象,基于两次丢包方法建立了一种新的主动队列管理算法TDPQW。该算法利用M/G/1排队模型推导了实际队列长度和等待时间的数学表达式,以此提出在队列头部和队中随机位置进行丢包的策略。同时,通过仿真实验对比分析了该算法与RED、DROP-TAIL算法的性能,结果表明TDPQW具有较好的适应性。
針對網絡擁塞現象,基于兩次丟包方法建立瞭一種新的主動隊列管理算法TDPQW。該算法利用M/G/1排隊模型推導瞭實際隊列長度和等待時間的數學錶達式,以此提齣在隊列頭部和隊中隨機位置進行丟包的策略。同時,通過倣真實驗對比分析瞭該算法與RED、DROP-TAIL算法的性能,結果錶明TDPQW具有較好的適應性。

In order to mitigate the network congestion, a novel active queue management algorithm TDPQW is proposed by twice dropping packets method. In this algorithm, the mathematic formula of actual queue length and waiting time are deducted with M/G/1 queuing model, and the dropping strategy in queue front and in queue random location is presented. A simulation is conducted to research on the algorithm performance between TDPQW and RED, as well as DROP-TAIL. The result shows that it has better adaptability for TDPQW.
