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

用户所认为的互联网常常被“最后一英里”所主宰？以及越来越多的“最后一米”，即他们的家庭网络、本地网络设备和互联网服务提供商提供的性能。故障、中断和限制可能来自各种来源，包括不兼容或配置错误的中间件、故意的ISP操作和过度缓冲的访问设备。该项目追求三个相互关联的目标，以促进以用户为中心的网络测量工具和技术，开发用户如何实际体验互联网的端到端视图。用户访问互联网的主要界面是网络浏览器——一个潜在的强大且无处不在的测量平台。该项目的第一个重点是Fathom，它将开发一组新的浏览器扩展，这些扩展可以实现全面的基于浏览器的测量，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他们自己的网站中来促进采用和创新。第二个重点是将Fathom扩展到移动领域，以便更好地理解移动访问如何影响和影响用户体验。移动设备现在定义了大量用户的互联网，但通过这些网络的访问特别容易受到操纵和控制。Fathom mobile将实现一套广泛的主动移动网络测量。最后，该项目旨在为未来的大规模测量平台提供信息，特别是那些使用客户预置设备的平台。随着这些设备变得更加强大和广泛部署，它为大规模测量研究提供了前所未有的机会。该推力将定义架构，以支持、保护和利用终端用户基础设施的多路主动测量实验。对大多数用户来说，定义互联网的是最后一英里和最后一米。这一提议涉及到对互联网边缘的全面测量，因为这个有利位置通常是限制用户互联网连接的最基本的来源。这个测量程序是全面的，包含了新的工具，增强了现有的经过良好验证的工具，并在用户网络中部署了一千个持久的测量节点。这项工作将使我们能够深入了解互联网的实际运作方式。用户和研究人员都将能够快速、可靠地测试连接是否存在问题和局限性。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进一步推进他们自己的努力。

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.
