物理和逻辑互联网连接的地图相互了解并保持一致,可以扩大范围并提高性能、鲁棒性和安全性分析的准确性。在本文中,我们描述了一种方法,用于连接物理和逻辑互联网地图,旨在实现一致的,跨层的表示。我们的方法是建设性的,并使用地理位置作为连接物理层和逻辑层的关键特征。我们开始通过使用在线源来构建物理连接的表示以标识容纳传输硬件的位置(即,PoP、托管中心、IXP等),以及基于最短路径通行权的这些之间的链路的近似位置。然后,我们利用标准数据源生成IP级和AS级逻辑连接的地图,并使用地理锚将这些数据嫁接到物理地图上。我们在一个名为互联网地理数据库(iGDB)的开源框架中实施我们的方法,该框架包括用于更新测量数据和确保内部一致性的工具。iGDB是为与ArcGIS一起使用而构建的,ArcGIS是一种地理信息系统,提供了广泛的空间分析和可视化功能。我们描述了iGDB实现的细节,并演示了如何在各种设置中使用它。
Maps of physical and logical Internet connectivity that are informed by and consistent with each other can expand scope and improve accuracy in analysis of performance, robustness and security. In this paper, we describe a methodology for linking physical and logical Internet maps that aims toward a consistent, cross-layer representation. Our approach is constructive and usesgeographic locationas the key feature for linking physical and logical layers. We begin by building a representation of physical connectivity using online sources to identify locations that house transport hardware (i.e., PoPs, colocation centers, IXPs, etc.), and approximate locations of links between these based on shortest-path rights-of-way. We then utilize standard data sources for generating maps of IP-level and AS-level logical connectivity, and graft these onto physical maps using geographic anchors. We implement our methodology in an open-source framework called the Internet Geographic Database (iGDB), which includes tools for updating measurement data and assuring internal consistency. iGDB is built to be used with ArcGIS, a geographic information system that provides broad capability for spatial analysis and visualization. We describe the details of the iGDB implementation and demonstrate how it can be used in a variety of settings.
