再论Internet AS级拓扑发现

Revisiting Internet AS-level Topology Discovery

Xenofontas Dimitropoulos, Dmitri Krioukov, George Riley

摘要:

在过去的几年里,互联网拓扑结构的准确模型的发展受到了广泛的关注。许多建议的模型是基于路由视图BGP表转储(BTD)派生的拓扑结构。然而,BTD不捕获互联网拓扑的所有AS链路,最重要的是隐藏的AS链路的数量是未知的,从而导致质量可疑的AS图。作为解决这个问题的第一步,我们引入了一个新的AS拓扑发现方法,结果更完整,更准确的图。此外,我们使用现有测量设施提供的数据,避免了额外测量基础设施的负担。我们部署我们的方法,并构建一个AS拓扑结构,至少有61.5%以上的AS链路比BTD派生的AS拓扑结构,我们检查。最后,我们分析了时间和拓扑性质的增强图,并指出从BTD派生AS-拓扑的差异。

英文摘要:

The development of veracious models of the Internet topology has received a lot of attention in the last few years. Many proposed models are based on topologies derived from RouteViews BGP table dumps (BTDs). However, BTDs do not capture all AS-links of the Internet topology and most importantly the number of the hidden AS-links is unknown, resulting in AS-graphs of questionable quality. As a first step to address this problem, we introduce a new AS-topology discovery methodology that results in more complete and accurate graphs. Moreover, we use data available from existing measurement facilities, circumventing the burden of additional measurement infrastructure. We deploy our methodology and construct an AS-topology that has at least 61.5% more AS-links than BTD-derived AS-topologies we examined. Finally, we analyze the temporal and topological properties of the augmented graph and pinpoint the differences from BTD-derived AS-topologies.
