IMR:MT: Internet Routing Experiments for the Cloud Era

新兴应用将越来越多地强调互联网的延迟、可靠性、吞吐量和抖动，从视频会议到AR/VR（增强现实/虚拟现实），到自动驾驶汽车和交通控制，再到远程健康监测和医疗保健。这些应用程序越来越集中于少数大型云和内容提供商。他们在世界各地部署服务器，为短距离的客户提供服务；它们直接与许多边缘网络对等，直接提供服务。学术研究人员缺乏这一重要背景的现实实验环境。现有的测试平台缺乏大型现代提供商的全球足迹和丰富的互连性，并且它们不能支持新兴应用程序所需的低延迟和高吞吐量流量。该项目将建立一个平台，使研究人员能够在忠实于现实世界云提供商的环境中进行互联网路由实验。为了使这一重要环境下的研究大众化，该项目将为现有的能够支持高性能的对等网络测试平台构建一个新的软件路由器；这些路由器将部署在六大洲的30个云站点，拥有近10,000个BGP对等点，极大地扩大了对等网络的覆盖范围；该项目将为研究人员建立并提供工具，以便在这种环境下进行实验，控制云站点和对等站点之间交换的路由和流量，并测量和存档结果。该项目的主要影响将是在全球部署、高度互联、具有粒度控制的云网络环境下实现研究访问的民主化，这是当今互联网乃至社会的关键和核心。通过将这一研究领域开放给没有特权访问超大型和云提供商的研究人员，该项目将使尖端研究能够塑造未来的互联网和互联网应用，造福社会。我们构建的高性能软件路由器在许多其他设置中也很有用。该项目还将开发课堂项目，包括在此环境中进行真实世界的实验，以帮助培养学生在这一关键领域的能力。该项目将扩展对等网络测试平台，扩展将在对等网络网站上记录：https://peering.ee.columbia.edu/This奖励反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Emerging applications will stress the Internet’s latency, reliability, throughput, and jitter more and more, from video conferencing, to AR/VR (augmented reality/virtual reality), to self-driving vehicles and traffic control, to remote health monitoring and health care. These applications are increasingly concentrated on a small number of large cloud and content providers. They deploy servers around the world to serve clients over short distances; and they peer directly with many edge networks to directly deliver services. Academic researchers lack realistic experimentation environments for this important setting. Existing testbeds lack the global footprint and rich interconnectivity of large modern providers, and they cannot support the low-latency and high-throughput traffic that emerging applications demand. This project will build a platform that enables researchers to conduct Internet routing experiments in an environment that is faithful to real-world cloud providers. To democratize research in this important setting, this project will build a new software router for existing PEERING testbed capable of supporting high performance; the routers will be deployed at 30 cloud sites across six continents, with nearly 10,000 BGP peers, dramatically expanding PEERING's footprint; and the project will build and make available tools for researchers to conduct experiments in this setting, controlling the routes and traffic exchanged between the cloud sites and the peers, and measuring and archiving the results.The primary impact of this project will be in democratizing access to research in the setting of a globally deployed, highly interconnected cloud network with granular control, one which is critical and central to today's Internet and hence society. By opening this research area to researchers without privileged access to hypergiants and cloud providers, the project will enable cutting-edge research that can shape the Internet and Internet applications of the future, benefiting society. The high-performance software router we build will also be useful in many other settings. The project will also develop class projects that involve real-world experiments in this setting, helping to train students in this critical area.The project will extend the PEERING testbed, and the extensions will be documented on the PEERING website: https://peering.ee.columbia.edu/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.
