摘要
现在广泛使用的主动队列管理(AQM)是目前队列管理的主流技术,但是它不能很好地区分来自响应流(如TCP会话)和非响应流(如UDP)的包。当拥塞出现的时候,将导致非响应流压制响应流并占有较多的带宽,而响应流却无法获得公平带宽。本文提出了一种闭环拥塞控制(CLCC)方案,大大改善了带宽分配的公平性。
Active Queue Management(AQM) that use extensively now is an essential technique, but it can' t differentiate between packets from responsive(such as TCP sessions) and non-responsive traffic(such as UDP). As congestion appears, it will lead the non-responsive traffic occupy the more bandwidth but the responsive don' t acquire the fair bandwidth. In this paper we propose a closed-loop congestion control (CLCC) scheme to largely improve the fairness of bandwidth allocation.
