摘　　要：对流行的几种CHOKe算法进行了分析,深入研究了CHOKe算法存在的对高速非适应流的处罚力度不够,不能够很好地实现带宽的公平性的问题。利用到达分组的统计特性,提出一种改进的CHOKe算法,仿真结果表明,在不保持流的状态信息下,该机制对非适应流具有更好的识别和控制能力,与其他CHOKe算法相比,能进一步加强对非适应流的惩罚,实现更为公平的带宽分配。Some popular CHOKe algorithms are analyzed. It is deeply studied that CHOKe algorithm can not punish the non-adaptive flow enough and distribute bandwidth fairly. An improved CHOKe algorithm is proposed in this paper. Simulation results indicate that the proposed mechanism has stronger recognition and control ability for non-adaptive flow without keeping the flow＇s state information. The improved CHOKe algorithm has better penalty performance for non-adaptive flows and achieves fairer allocation of bandwidth comparing to other CHOKe algorithms.

关 键 词：主动队列管理 CHOKE 非适应流 公平性
