IMR:MT: Internet Routing Experiments for the Cloud Era

新兴应用将越来越强调互联网的延迟、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），从自动驾驶车辆和交通控制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，为短距离客户提供服务;他们直接与许多边缘网络进行对等，直接提供服务。学术研究人员缺乏现实的实验环境，这一重要的设置。现有的测试平台缺乏大型现代供应商的全球足迹和丰富的互连性，并且无法支持新兴应用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。为了使这一重要背景下的研究民主化，该项目将为现有的PEGNET测试平台建立一个新的软件路由器，能够支持高性能;这些路由器将部署在六大洲的30个云站点，有近10，000个BGP对等点，大大扩大PEGNET的足迹;该项目将为研究人员构建并提供工具，以在此环境中进行实验，控制云站点和对等点之间交换的路由和流量，该项目的主要影响将是在全球部署、高度互连、具有粒度控制的云网络环境中实现研究的民主化，这对当今的互联网乃至社会至关重要。通过向没有超级巨头和云提供商特权的研究人员开放这一研究领域，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也将在许多其他设置中有用。该项目还将开发涉及此设置的真实世界实验的课堂项目，帮助在这一关键领域培训学生。该项目将扩展PEGNET测试平台，并将在PEGNET网站上记录扩展：https://peering.ee.columbia.edu/This奖项反映了NSF的法定使命，并已被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。

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.
