For decades, the Border Gateway Protocol (BGP) has served as the glue of the Internet, determining the routes that Internet traffic takes from source to destination. While it has supported the tremendous growth of the Internet, the Internet has changed and the applications that run on it are very different from those the Internet originally supported. BGP is not performance-aware, and so it may not choose the best-performing routes. Previous work found that the routes it chooses are often good enough for traditional Internet applications like web browsing, email, and streaming video that can tolerate good-enough performance and temporary blips. However, emerging use cases such as remote health monitoring, telemedicine, virtual reality/adaptive reality, self-driving cars, and robotized factories require reliable low-latency, high-throughput performance to support real-time, interactive, and sometimes critical applications. Despite these needs, BGP cannot simply be replaced or upgraded, as tens of thousands of independent networks rely on it to interconnect and exchange traffic.The project's objectives are twofold: (1) understanding the circumstances in which BGP’s performance and availability are "good enough" and identifying when this is not so; and (2) proposing systems for enhancing BGP’s performance and availability, without requiring undeployable changes to BGP itself. If successful, the project will be the basis for the Internet services of tomorrow, with dependable real-time interactions over rich applications, providing new capabilities to users around the world.The project will investigate the performance and availability of BGP and explore whether and how BGP can be used to optimize performance for the next generation of real-time Internet-based services. The research will address these questions in the context of three critical challenges in modern Internet application delivery: determining to which site to direct the user, routing across the wide area to the site, and selecting a route back to the client from the site. It will develop novel approaches to using BGP that enable it to serve as the underpinning of emerging critical applications. The project will combine theoretical analyses with measurements from long-standing collaborations with content and cloud providers and evaluate the results using system prototypes deployed on the real Internet.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.

几十年来，边境网关协议（BGP）一直是互联网的胶水，确定了互联网流量从源到目的地的路线。尽管它支持了互联网的巨大增长，但互联网已经改变，其运行的应用程序与互联网最初支持的应用程序大不相同。 BGP不感知性能，因此它可能不会选择表现最佳的路线。先前的工作发现，它选择的路线通常足以用于传统的Internet应用程序，例如网络浏览，电子邮件和流视频，这些视频可以忍受良好的性能和临时片段。但是，新兴的用例，例如远程健康监测，远程医疗，虚拟现实/自适应现实，自动驾驶汽车和机器人的工厂需要可靠的低延迟，高通量性能，以支持实时，互动，有时甚至关键应用。尽管需要这些需求，但BGP不能简单地被替换或升级，因为成千上万的独立网络依靠它来互连和交换流量。项目的目标是双重的：（1）了解BGP的性能和可用性“足够好”并确定何时不是这样； （2）提出用于增强BGP的性能和可用性的系统，而无需对BGP本身进行不可剥削的更改。如果成功的话，该项目将成为明天的互联网服务的基础，对丰富的应用程序提供可靠的实时互动，并为世界各地的用户提供新的功能。该项目将调查BGP的性能和可用性，并探索如何以及如何使用以及如何使用BGP来优化下一代实时Internet基于Internet的服务的性能。这项研究将在现代互联网应用程序交付中的三个关键挑战的背景下解决这些问题：确定要指导用户的站点，将跨区域路由到该站点，并从网站中选择回到客户的路线。它将开发使用BGP的新颖方法，使其能够充当新兴关键应用的潜在方法。该项目将将理论分析与与内容和云提供商进行长期合作的测量结合，并使用在真实互联网上部署的系统原型评估结果。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来通过评估来获得支持的。
