IMR: RI-P: Programmable Closed-loop Measurement Platform for Last-Mile Networks

当今社会在工作、教育、医疗保健和娱乐方面严重依赖各种基于internet的服务，而接入（或最后一英里）网络的质量决定了这些服务的体验质量。在美国，接入网络的质量因地区、社区和人口而异，导致数字不平等。政策制定者有兴趣弥合这一差距；要做到这一点，他们需要了解访问质量的状态。该合作项目将探索新的网络测量和分析平台的设计和部署策略，使政策制定者能够大规模评估接入网络的质量。该合作规划项目将汇集加州大学圣巴巴拉分校和芝加哥大学的研究人员，探索可编程和可扩展数据收集平台的可行性，通过特定用例展示闭环数据收集的价值，并使用从芝加哥住宅部署收集的数据评估不同的扩展策略。此外，该项目将组织一个研讨会，邀请来自行业、政府和学术界的不同利益相关者来确定拟议平台的扩展策略、新功能和具体用例。提议的平台可以回答从特定社区的互联网性能和基础设施状态到支持特殊/新应用（例如，视频会议、远程医疗等）所需的互联网速度和性能特征等问题。这种能力将赋予决策者和其他利益相关者权力，如网络研究人员、网络运营商和最终用户。按照设想，开源工具、方法和数据将成为这些组织所依赖的标准，以评估互联网接入网络中问题的性质，以及评估各种政策干预、计划和基础设施投资等的有效性。项目网站：https://pinetrics.cs.ucsb.edu/This该奖项反映了美国国家科学基金会的法定使命，并通过基金会的知识价值和更广泛的影响审查标准进行评估，认为值得支持。

Today's society relies heavily on various Internet-based services for work, education, health care, and entertainment, and the quality of access (or last-mile) network dictates the quality of experience for these services. The quality of access networks in the US varies across different regions, communities, and demographics, contributing to digital inequities. Policymakers are interested in bridging this gap; to do so, they require understanding the state of access quality. This collaborative project will explore the design and deployment strategies for a new network measurement and analytics platform that enables policymakers to assess access networks' quality at scale.This collaborative planning project will bring together researchers from the University of California Santa Barbara and the University of Chicago to explore the feasibility of a programmable and scalable data-collection platform, demonstrate the value of closed-loop data collection with specific use-cases, and evaluate different scaling strategies using the data collected from its residential deployments in Chicago. Additionally, this project will organize a workshop inviting different stakeholders from industry, government, and academia to identify scaling strategies, new features, and concrete use cases for the proposed platform.The proposed platform can answer questions ranging from the state of the Internet performance and infrastructure in specific neighborhoods to the Internet speeds and performance characteristics required to support special/new applications (e.g., video conferencing, telehealth, etc.). Such capabilities will empower policymakers and other stakeholders, such as networking researchers, network operators, and end users. It is envisioned that the open-source tools, methods, and data will become the standard that these organizations rely on to both assess the nature of problems in Internet access networks, as well as to assess the effectiveness of various policy interventions, programs, and infrastructure investments, and so forth.
