The FLOTO project will build a discovery testbed: a large, distributed observational instrument built for the purpose of advancing research on access networks, i.e., the “last mile” networks that connect individuals, homes, and businesses to their service provider. In practical terms, the instrument will consist of roughly one-thousand edge devices deployed across a major urban area (Chicago) and several university campuses. These devices will be instrumented with broadband diagnostic tests to obtain observation data that will allow network scientists to gain insight into access network performance. To make this system possible, FLOTO will develop a fleet management framework for edge devices, extend and deploy a set of existing active network measurements developed as a result of community effort, and manage further community contributions to shape the observational capacity of the instrument. The outcomes of this project will provide an unprecedented capability for observing and understanding the dynamics and evolution of the Internet, and ultimately provide an invaluable tool for research and policymaking. In particular, it will allow researchers to investigate where disparities exist in terms of deployment, availability, reliability, and performance that lead to the “digital divide” in society -- and ultimately catalyze new solutions that are likely to work for every member of society. On a more general level, this project will also create a blueprint for a discovery testbed at a large scale and pioneer new allocation and sharing methods that can be adapted to different types of discovery. Finally, through a new collaborative agreement with the City Colleges of Chicago, this project will provide opportunities for practical, hands-on training for students as part of two-year degree programs in computer networking.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Floto项目将建立一个测试的发现：为了推进访问网络的研究，即将个人，房屋和企业与他们的服务提供商联系起来的“最后一英里”网络，即“最后一英里”网络。实际上，该工具将由大约一千个边缘设备组成，该设备部署在主要城市（芝加哥）和几个大学校园中。这些设备将通过宽带诊断测试进行仪器，以获取观察数据，这将使网络科学家能够深入了解访问网络性能。为了使该系统成为可能，Floto将为边缘设备开发一个车队管理框架，扩展和部署由于社区努力而开发的一组现有的主动网络测量，并管理进一步的社区贡献以塑造仪器的观察能力。该项目的结果将为观察和了解互联网的动态和演变提供前所未有的能力，并最终为研究和决策提供了宝贵的工具。特别是，它将允许研究人员研究导致社会中“数字鸿沟”的部署，可用性，可靠性和绩效的分布，并最终催化可能对社会成员有效的新解决方案。在更一般的层面上，该项目还将为大规模的发现测试台创建蓝图，并开拓者的新分配和共享方法可以适应不同类型的发现。最后，通过与芝加哥城市学院的新合作协议，该项目将为学生提供实用，动手培训的机会，这是计算机网络上两年学位课程的一部分。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的审查标准通过评估来通过评估来获得的支持。
