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，边界网关协议 (BGP) 一直充当互联网的粘合剂，决定互联网流量从源到目的地的路由。虽然它支持了互联网的巨大发展，但互联网已经发生了变化，应用程序也发生了变化。其上运行的路由与互联网最初支持的路由有很大不同，因此它可能不会选择性能最佳的路由，它选择的路由通常足以满足 Web 等传统互联网应用的需求。可以容忍的浏览、电子邮件和流媒体视频然而，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工厂等新兴用例需要可靠的低延迟、高吞吐量性能来支持实时。尽管有这些需求，但 BGP 不能简单地替换或升级，因为数以万计的独立网络依靠它来互连和交换流量。该项目的目标有两个：(1) 了解其中的情况。 BGP 的性能和可用性“足够好”，并确定何时不够好；以及 (2) 提出增强 BGP 性能和可用性的系统，而不需要对 BGP 本身进行不可部署的更改。 如果成功，该项目将成为互联网的基础。未来的服务，通过丰富的应用程序进行可靠的实时交互，为世界各地的用户提供新的功能。该项目将研究 BGP 的性能和可用性，并探索是否以及如何使用 BGP 来优化下一代网络的性能。即时的基于互联网的服务将在现代互联网应用交付的三个关键挑战的背景下解决这些问题：确定将用户引导到哪个站点、跨广域路由到该站点以及选择返回客户端的路由。它将开发使用 BGP 的新颖方法，使其成为新兴关键应用程序的基础。该项目将结合理论分析和与内容和云提供商长期合作的测量结果，并使用系统原型评估结果。部署在真实的互联网上。该奖项反映了 NSF法定使命，并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，被认为值得支持。
