P2P Traffic Control Realizing Fairness among Users

P2P业务量的增长是电信运营中最重要的技术问题之一。对P2P用户的不公平可能会导致流量控制，这是近年来引起网络中立性的热门讨论。本研究试图从网络侧和终端主机侧两个方面为“实现P2P用户公平性的流量控制”寻找技术解决方案。在P2P内容分发系统中，一个接收方从多个源中的每一个源接收内容的一部分，这意味着只有一个接收方可以获得整个P2P系统的内容分发状态。因此，我们开发了接收者驱动的拥塞控制系统，P2P接收者公平地共享瓶颈链路带宽与非P2P流。我们还开发了几种流量控制方案，实现公平共享的网络资源的内容分发，例如AQM在路由器解决公平之间的TCP会话使用不同的操作系统和公平的拥塞控制数据中心网络。

Recent increase of P2P traffic volume is one of the most important technical issues for telecommunications operation. Unfair condition for P2P users might cause traffic control making use of deep inspection of traffic, which is evoking hot discussion for network neutrality recently. In this study, we try to find technical solutions for “traffic control realizing fairness among P2P users” from both of network side and end-host side. In P2P content distribution system, one receiver receives some portion of content from each of multiple sources, which means only a receiver can obtain content distribution status of the whole P2P system. So, we develop receiver-driven congestion control system with which P2P receiver fairly shares bottleneck link bandwidth with non-P2P flows. We also develop several traffic control schemes achieving fair share of network resources for content distribution, e.g. AQM at router resolving fairness among TCP sessions using different OS and fair congestion control for data center networks.
