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.

全球互联网服务，如网络搜索、社交网络、视频传播和云计算，都是建立在数据中心之上的，而数据中心是装满计算机的大型仓库。数据中心中的计算机通过网络连接在一起并连接到互联网。如果该网络出现故障，那么它连接的计算机及其支持的互联网服务也会出现故障。该项目的目标是将这些网络每月的停机时间减少一到两个数量级。该项目将探索两个组件的设计，这两个组件可以显着减少网络停机时间。 其中一个组件将是一个新的高可用性控制平面，其中包括一个新的复制协议，该协议为外部故障检测器的故障提供强大的一致性和弹性，同时保留当前可用性较低的设计（例如，小型设计）的许多所需属性。资源占用）尽可能。另一个组件将是一个自动化管理平面，它将提高在网络上指定管理操作 (MOp) 的抽象级别，从而允许自动化软件综合和管理实现复杂网络 MOp 所需的步骤序列，例如升级全球互联网服务是现代生活不可或缺的一部分，提高其可用性将使社会受益。该项目计划包括开发软件原型以及与大型互联网服务密切合作，以增加技术转让的可能性。 该项目的研究将由研究生和本科生进行，他们将学习网络如何工作、如何构建和改进网络，以及如何构建和改进控制网络的计算机系统。 这些技能在未来几年可能会变得越来越重要。
