基于跳数的公平性增强RED及其分类器实现

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时RED算法进行简单的修改,实现了一个公平性增强的RED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.%To solve unfairness bandwidth allocation problem induced by different RTT and multiple congestion links; we proposed a fairness enhancement RED(FERED) based on the measurement results in the real Internet in this paper. FE-RED 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.
