摘要
将网络拥塞控制的公平性研究划分为在同质流网络中的公平性和在异质流网络中的公平性两个方面,公平性研究在两类网络中均有重大的意义。依此划分,分别介绍了近年来拥塞控制公平性研究的重要进展。同质流网络中公平性研究主要是围绕解决TCP流的RTT歧视这一问题而展开和深入的;异质流网络中公平性研究主要是围绕保护正当行为流的问题而不断推进的,目前的研究热点是对用户公平的AQM算法。最后对拥塞控制公平性研究领域未来有价值的研究问题给出了预测,并阐述了对这几个问题的理解。
Divide the fairness research of network congestion control into two subareas : homogeneous flow network and heterogeneous flow network, in both of which the fairness problem is of great importance. According to classification, the important recent advances in each subarea are introduced. The central problem in homogeneous flow network is the removal of round-trip-time bias, while the reasearches in heterogeneous flow network are carried out mainly to protect normal flows from the misbehavior ones. The hot spot in this field is the user-fair AQM algorithms. In the end predic- tion on some future interesting directions are given, togethor with some authors insights into them.
