Internet AS级拓扑图的时间序列:四种模式和一种模型

Time series of Internet AS-level topology graphs: four patterns and one model

Lian-dong Liu, Ke Xu

摘要:

研究者们提出了各种各样的互联网拓扑模型。然而,几乎所有的方法都集中在基于一个静态源图生成一个图。另一方面,随着时间的推移,随着节点和边的增加和删除,互联网拓扑结构不断演变。如果模型是基于过去的所有拓扑结构,而不是其中之一,它将更准确,更接近真实世界的拓扑结构。本文研究了两个不同来源的互联网As级拓扑时间序列,发现它们都服从四种相同的动态图模式。在此基础上,提出了一种基于过去的所有拓扑来推断未来拓扑的模式。通过理论和实验分析,我们证明了我们的模型生成的拓扑结构可以匹配静态和动态图形模式。此外,模型中的参数是有意义的。最后,我们从理论和实验上证明了这些参数直接关系到一些重要的图形特征。

英文摘要:

Researchers have proposed a variety of Internet topology models. However almost all of them focus on generating one graph based on one single static source graph. On the other hand, Internet topology is evolving over time continuously with the addition and deletion of nodes and edges. If a model is based on all the topologies in the past, instead of one of them, it will be more accurate and closer to the real world topology. In this paper, we study the Internet As-level topology time-series from two different sources and find that both of them obey four same dynamic graph patterns. Then we propose a mode that can infer the topology in the future based on all the topologies in the past. Through theoretical and experimental analysis, we prove the topology that our model generates can match both the static and dynamic graph patterns. In addition, the parameters in the model are meaningful. Finally, we theoretically and experimentally prove that these parameters are directly related to some important graph characteristics.
