Global Internet services, such as web search, social networking, video dissemination, and cloud computing are built on data centers that are large warehouses full of computers. The computers in the data centers are connected together, and to the Internet, by a network. If that network goes down then the computers it connects and the Internet services they support also go down. This project aims to decrease, by one to two orders of magnitude, how long those networks are down each month.The project will explore the design of two components that can contribute significantly towards decreasing network downtime. One component will be a new highly-available control plane that will include a new replication protocol that provides strong consistency and resilience to the failure of an external failure detector while retaining as many of the desirable properties of current less-available designs (e.g., small resource footprint) as possible. The other component will be an automated management plane that will raise the level of abstraction of specifying a management operation (MOp) on the network, thereby allowing automated software to synthesize and manage the sequence of steps necessary to achieve a complex network MOp such as upgrading software on a large network.Global Internet services are an integral part of modern life and increasing their availability will benefit society. The project plans include developing software prototypes and working closely with large Internet services to increase the likelihood of technology transfer. The research in the project will be conducted by graduate students and undergraduate students that will learn how networks work, how to build and improve them, and how to build and improve the computer systems that control them. Each of these skills is likely to be increasingly important in the coming years.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.

Web搜索，社交网络，视频传播和云计算等全球互联网服务建立在充满计算机的大型仓库的数据中心。数据中心中的计算机通过网络连接在一起，并连接到Internet。如果该网络下降，则它连接的计算机，他们支持的Internet服务也会下降。该项目的目标是减少一到两个数量级，这些网络每个月都会下降多长时间。该项目将探索两个组件的设计，这些组件可以为减少网络停机时间做出重大贡献。 一个组件将是一种新的高度可用的控制平面，它将包括一种新的复制协议，该协议可为外部故障检测器的故障提供强大的一致性和韧性，同时保留了当前较低的可易于效果的许多理想特性（例如，小型小资源足迹）尽可能。另一个组件将是一个自动化管理平面，它将提高网络上指定管理操作（MOP）的抽象水平，从而允许自动化软件合成和管理实现复杂网络MOP（例如升级）所需的步骤顺序大型网络上的软件。GlobalInternet服务是现代生活不可或缺的一部分，增加其可用性将使社会受益。该项目计划包括开发软件原型并与大型互联网服务紧密合作，以增加技术传输的可能性。 该项目的研究将由研究生和本科生进行，这些学生将学习网络的工作方式，如何构建和改进它们以及如何构建和改善控制它们的计算机系统。 在未来几年中，这些技能中的每一个都可能越来越重要。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影响的评论标准来评估值得支持的。
