摘要
在自治系统(Autonomous System, AS)层面准确、完整的互联网拓扑建模对于未来的协议设计、性能评估、仿真和分析至关重要,但如何构建其准确的表示仍然是一个挑战。在本文中,我们收集了来自LG服务器的BGP路由公告。通过查询LG服务器,我们建立了一个大约116 K AS链路的AS拓扑估计,从中我们发现了11 K新的AS链路和686个新的AS。我们得出结论,从LG服务器收集BGP踪迹可以帮助增强BGP收集器项目(例如RouteViews)对AS拓扑的当前视图。
AS-level topology collection through looking glass servers
While accurate and complete modeling of the Internet topology at the Autonomous System (AS) level is critical for future protocol design, performance evaluation, simulation and analysis, still it remains a challenge to construct its accurate representation. In this paper, we collect BGP route announcements of ASes from Looking glass (LG) servers. By querying LG servers, we build an AS topology estimate of around 116 K AS links, from which we discover 11 K new AS links and 686 new ASes. We conclude that collecting BGP traces from LG servers can help enhance the current view of the AS topology from the BGP collector projects (e.g., RouteViews).
