AI总结:

该研究通过大规模互联网流量数据分析发现叶节点和孤立链路的重要性,提出双参数修正Zipf-Mandelbrot分布可准确描述流量统计特征,且模型参数可区分网络流、关联网络拓扑。

摘要:

互联网正在改变我们的社会,因此有必要对互联网流量进行定量研究。我们团队收集并整理了目前最大的公开可用互联网流量数据集。在MIT SuperCloud(麻省理工超级云)上使用10000个处理器对500亿个数据包进行分析后,我们发现了一个新现象:此前未被关注的叶节点和孤立链路在互联网流量中具有重要作用。进一步分析表明,双参数修正Zipf-Mandelbrot分布能够准确描述多种源/目的统计特征,这些统计基于跨越数年、覆盖多个大陆的数据集,在10万到1亿个数据包的移动采样窗口上计算得到。测得的模型参数可以区分不同的网络流,且模型的叶参数与不同底层网络拓扑中的流量占比强相关。

英文摘要:

The Internet is transforming our society, necessitating a quantitative understanding of Internet traffic. Our team collects and curates the largest publicly available Internet traffic data sets. An analysis of 50 billion packets using 10,000 processors in the MIT SuperCloud reveals a new phenomenon: the importance of otherwise unseen leaf nodes and isolated links in Internet traffic. Our analysis further shows that a two-parameter modified Zipf-Mandelbrot distribution accurately describes a wide variety of source/destination statistics on moving sample windows ranging from 100{,}000 to 100{,}000{,}000 packets over collections that span years and continents. The measured model parameters distinguish different network streams, and the model leaf parameter strongly correlates with the fraction of the traffic in different underlying network topologies.
