通过提供一组允许数据平面和控制平面测量值的分布式有利位点来增强我们对Internet连接性和性能的可见性。在本文中允许系统地使用LG的自动测量工具。单个平台并自动化LG功能的发现和使用。截至2015年12月，无需违反各种LG查询率限制的查询。 297自治系统。
Looking glasses (LG) servers enhance our visibility into Internet connectivity and performance by offering a set of distributed vantage points that allow both data plane and control plane measurements. However, the lack of input and output standardization and limitations in querying frequency have hindered the development of automated measurement tools that would allow systematic use of LGs. In this paper we introduce Periscope, a publicly-accessible overlay that unifies LGs into a single platform and automates the discovery and use of LG capabilities. The system architecture combines crowd-sourced and cloud-hosted querying mechanisms to automate and scale the available querying resources. Periscope can handle large bursts of requests, with an intelligent controller coordinating multiple concurrent user queries without violating the various LG querying rate limitations. As of December 2015 Periscope has automatically extracted 1,691 LG nodes in 297 Autonomous Systems. We show that Periscope significantly extends our view of Internet topology obtained through RIPE Atlas and CAIDA’s Ark, while the combination of traceroute and BGP measurements allows more sophisticated measurement studies.
