摘　　要：随着信息化时代的蓬勃发展,信息传输已经渗透到了日常生活和商业活动的方方面面,成为不可或缺的一部分。然而,这种信息传输的大规模增长也带来了一系列问题,其中包括网络拥塞等现象变得愈加普遍。在应对网络拥塞问题时,主动队列管理(AQM)算法显得尤为重要,其中包括随机早期检测(RED)和自适应平均队列大小及其变化率(AQMRD)算法等。尽管这些算法已经起到了一定作用,但在提升吞吐量与服务质量方面仍有进步的空间。针对已有算法的不足,文中提出一种基于AQMRD的改进算法,即Huber-AQMRD算法。该算法通过引入“Huber”损失函数,更准确地评估队列大小与期望值之间的差异,从而优化了丢包函数的设计。通过ns3仿真实验验证,Huber-AQMRD算法在降低丢包率的同时,提高了网络吞吐量和服务质量,对于解决大规模增长的信息传输下的网络拥塞问题,提升网络性能和用户体验具有重要意义。With the vigorous development of the information age,information transmission has permeated every aspect of people′daily lives and commercial activities and become an indispensable part.However,this massive growth in information transmission has also brought about a series of problems,of which the network congestion has become increasingly common.In addressing the issue of network congestion,the active queue management(AQM)algorithms play a crucial role,including the algorithm of random early detection(RED)and the algorithm of adaptive mean queue size and its rate of change:queue management with random dropping(AQMRD).However,although these algorithms have worked to some extent,there is still room for improvement in throughput and quality of service.In view of the shortcomings of the existing algorithms,this paper proposes an improved algorithm based on AQMRD,namely the Huber-AQMRD algorithm.This algorithm assesses the differences between queue size and expected value more accurately by introducing the loss function″Huber″,so as to optimize the design of packet dropping function.It is verified by ns3 simulation experiments that the Huber-AQMRD algorithm improves network throughput and the quality of service while reducing packet loss rate,so it holds significant importance in eliminating the network congestion under the background of massive growth of information transmission and enhancing the network performance and user experience.
