摘要:
随着Internet的迅速发展,致使IP业务的快速增长和多样化,用户数量急剧增加,网络流量呈爆炸式增长,网络拥塞问题变得越来越严重,因此服务质量（QoS）成为了当今世界研究热点之一。为了能达到相对的QoS的性能指标,拥塞控制发挥着相当重要的作用,而主动式队列管理（Active Queue Management,AQM）机制又是实现拥塞控制的重要手段之一,AQM成为了IP网络拥塞控制研究领域中备受关注和深入研究的热点问题。文中在增强CHOKe算法的公平性上,提出一种新的基于时延抖动的AQM算法-CZ-CHOKe。路由器通过时延抖动和队列的平均队长检测网络拥塞,同时采用动态采样击中和自适应丢包技术。仿真结果表明,该算法能有效地保护响应流,提高非响应流的击中概率,提高其算法的公平性
Abstract:
With the rapid development of Internet,resulted in the IP services growth rapidly and diversification. At the same time as the number of users increase dramatically, network traffic exploding, network congestion problems become more serious, so the quality of service （ QoS ） has become one of the world＇s research focuses. In order to achieve the relative performance of QoS, congestion control plays an important role,while the active queue management （ Active Queue Management,AQM） mechanism is one of important means to achieve congestion control, AQM has become an attention and in-depth study of the hot issues in the field of IP network congestion control. Based on the fairness of the CHOKe, proposed a new delay jitter algorithm. The routers detect network congestion through the delay jitter and the average queue length,uses dynamic sampling hit and adaptive packet loss technology. The simulation experimental results show that the algorithm can protect the response stream effectively and improve the hit probability of non-response flow ,improve the fairness of the algorithm
