文中主要研究了主动队列管理( AQM)的公平性算法。利用gCHOKe的多次击中能近似识别并惩罚非响应流,提高gCHOKe击中的有效性以及惩罚非响应流的力度,是提高算法公平性的关键因素。在gCHOKe算法的基础上提出了一种基于预处理的pgCHOKe(preprocess based-gCHOKe)公平性算法,通过对数据流进行预处理筛选后再进行gCHOKe击中,提高了击中的有效性。仿真实验表明pgCHOKe相比RED、gCHOKe和BLUE,可以获得更低的UDP吞吐量,是有效的、公平的。

In this paper,study the fairness of the active queue management algorithm. The gCHOKe hit more than once improves the ef-fectiveness and the force of punishing non-response flows are the crucial factors to enhance the fairness of algorithm,is used to approxi-mately identify and punish non-response flows. Based on the gCHOKe,a new active queue management algorithm,pgCHOKe ( prepro-cess based-gCHOKe),which based on the preprocessing has been proposed. The algorithm improves effectiveness of gCHOKe hit through using preprocess firstly, then the pgCHOKe hit. Simulation results show that compared with RED, gCHOKe and BLUE, pg-CHOKe is able to get lower throughput,so it is effective and fair.
