由于需要对Internet网络进行设计改进以使其对高流量异常具有鲁棒性,我们分析了Internet2网络中连续异常到达时间间隔的统计特性。使用几种统计技术,我们证明了在Internet2中的所有单向链接中,这些到达间隔时间具有尾部概率像幂律一样衰减的分布。这些重尾分布具有不同的尾指数,在某些情况下意味着无限的方差。我们建立了到达间隔时间可以建模为独立的、同分布的随机变量,并提出了它们的分布模型。这些发现使我们能够使用更新理论的工具,从而使我们能够估计下一个异常到达的等待时间的分布。我们证明了等待时间随机地大大长于到达之间的时间,并且在某些情况下可能具有无限的期望值。我们的所有发现都以适当的图表形式制成表格并显示,包括相关的密度估计。
Motivated by the need to introduce design improvements to the Internet network to make it robust to high traffic volume anomalies, we analyze statistical properties of the time separation between arrivals of consecutive anomalies in the Internet2 network. Using several statistical techniques, we demonstrate that for all unidirectional links in Internet2, these interarrival times have distributions whose tail probabilities decay like a power law. These heavy-tailed distributions have varying tail indexes, which in some cases imply infinite variance. We establish that the interarrival times can be modeled as independent and identically distributed random variables, and propose a model for their distribution. These findings allow us to use the tools of of renewal theory, which in turn allows us to estimate the distribution of the waiting time for the arrival of the next anomaly. We show that the waiting time is stochastically substantially longer than the time between the arrivals, and may in some cases have infinite expected value. All our findings are tabulated and displayed in the form of suitable graphs, including the relevant density estimates.
