| 摘 要： | 为了同时兼顾改善不同往返时延(RTT)和多拥塞链路所引发的不公平性问题，在实际网络环境测量结果的基础上，提出了利用数据包所经过的路由器跳数来增强公平性的思路，并构造了一个二维两类分类器来对REI)算法进行简单的修改，实现了一个公平性增强的REI)算法。NS2下的模拟表明，该算法可有效增强公平性，而且具有实现简单、易于在实际网络中部署的优点。

| Abstract: | To solve unfairness bandwidth allocation problem induced by different RI I} and multiple congestion links,we proposed a fairness enhancement RED(FERED) based on the measurement results in the real Internet in this paper.FERED utilizes the hop-counts to improve fairness and constructs a two-category classifier to modify the RED algorithm.Simulation results in NS2 show that FERED can efficiently improve fairness. Moreover, FERED can be deployed easily. |
