NeTS: Large: Collaborative Research: User-Centric Network Measurement

用户对互联网的看法往往是由“最后一英里”主导的。并且越来越多地是“最后一米”，即由他们的家庭网络、本地网络设备和因特网服务提供商提供的性能。 故障、中断和限制可能由各种来源引起，包括不合规或配置错误的中间盒、故意的ISP操纵和过度缓冲的接入设备。 该项目追求三个相互关联的推动力，以促进以用户为中心的网络测量工具和技术，开发一个端到端的用户如何实际体验互联网的视图。 用户与互联网的主要接口是网络浏览器--一个潜在的强大和无处不在的测量平台。 该项目的第一个推力，称为Fathom，将开发一套新的浏览器扩展，使全面的从浏览器测量，包括自动故障调试工具。 此外，Fathom API将通过允许Web开发人员将任意诊断或性能分析代码嵌入到自己的网站中来促进采用和创新。第二个推力是将Fathom扩展到移动的领域，以更好地了解移动的访问如何影响和影响用户体验。移动的设备现在为大量用户定义了互联网，然而通过这些网络的访问特别容易受到操纵和控制。 Fathom移动的将实现广泛的主动移动的网络测量套件。最后，该项目旨在为未来的大规模测量平台提供信息，特别是那些利用客户端设备的平台。 随着这些设备变得越来越强大和广泛部署，它为大规模测量研究提供了前所未有的机会。 这一推动力将定义利用最终用户基础设施的支持、安全和多路主动测量实验的体系结构。这是定义大多数用户的互联网的最后一英里和最后一米。 这一建议涉及全面努力衡量互联网的边缘，因为这一Vantage位置往往是限制用户互联网连接的最根本原因。 这项测量计划是全面的，包括新的工具，增强现有的有效工具，并部署在用户的网络中的一千个持久的测量节点。这项工作将使重要的洞察力，互联网实际上是如何运作的。 用户和研究人员都将能够快速、稳健地测试连接，以发现问题和限制。此外，该项目将使其他研究人员可以使用的工具和基础设施，以进一步自己的努力。

What users perceive as the Internet is often dominated by the "last mile? and increasingly the "last meter" that is the performance provided by their home network, local network equipment, and Internet Service Provider. Failures, outages, and limitations may arise from a variety of sources, including non-compliant or misconfigured middleboxes, deliberate ISP manipulations, and overbuffered access equipment. This project pursues three inter-related thrusts toward facilitating user-centric network measurement tools and techniques that develop an end-to-end view of how users actually experience the Internet. The user's primary interface to the Internet is the web browser -- a potentially powerful and ubiquitous measurement platform. The project's first thrust, termed Fathom, will develop a set of new browser extensions that enable comprehensive from-the-browser measurement, including automatic failure-debugging tools. Further, the Fathom API will promote adoption and innovation by allowing web developers to embed arbitrary diagnostics or performance analysis code into their own websites.The second thrust is to extend Fathom to the mobile space to better understand how mobile access affects and influences user experience. Mobile devices now define the Internet for a large cohort of users, yet access via these networks is particularly prone to manipulation and control. Fathom mobile will enable a broad suite of active mobile network measurements.Finally, the project seeks to inform future large-scale measurement platforms, especially those utilizing customer premise equipment. As such equipment becomes more powerful and widely deployed, it represents an unparalleled opportunity for large-scale measurement research. This thrust will define the architecture to support, secure, and multiplex active measurement experiments that utilize end-user infrastructure.It is the last mile and the last meter that define the Internet for most users. This proposal involves a comprehensive effort to measure the edge of the Internet, as this vantage point is often the most fundamental source of limitations on the user's Internet connection. This measurement program is comprehensive, encompassing new tools, enhancing existing well-validated tools, and deploying a thousand persistent measurement nodes within users'networks.This work will enable significant insight into how the Internet actually operates. Both users and researchers will be able to test connections quickly and robustly for problems and limitations. Further, the project will enable tools and infrastructure that other researchers can use to further their own efforts.
