The Transmission Control Protocol and its socket interface are used by most network applications today---viewed as a software program, it is likely the most popular one in the world. Over thirty years old, this program is now showing signs of age. Web, mobile, and embedded applications use it in unanticipated ways (many interacting flows of different lengths with different objectives); it does not properly support mobile devices with multiple networks; it does not allow an application to adapt quickly to changing network conditions; it does not work well in fast datacenter networks; and it has a fruitless, adversarial relationship with in-network "middleboxes".App-Centric Transport (ACT) aims to solve these problems. Unlike today's transport architecture, ACT takes application objectives into account in making its transmission decisions. ACT uses a computer-generated transmission control program, which takes models of the workload and objectives to automatically synthesize protocols. This program (Remy) serves both as a way to implement protocols and as a design tool to answer fundamental questions about congestion control. ACT explores centralized control over transmission and path selection for datacenters, and uses machine learning classifiers to select the best network on mobile devices. It aims to resolve tussles between endpoint transport and in-network middleboxes by viewing middlebox interposition as a generalization of multi-path transport. Project participants are collaborating with Facebook and Google on some of these ideas. The education plan introduces protocol design contests where students can run and measure their protocols over trace data and compare their protocols on a leaderboard.

当今大多数网络应用程序都使用传输控制协议及其套接字界面 - 被视为软件程序，它可能是世界上最受欢迎的程序。三十多年来，该计划现在显示出年龄的迹象。 Web，移动和嵌入式应用程序以意外的方式使用它（许多不同长度的相互作用的流动与不同的目标）；它不能适当地支持具有多个网络的移动设备；它不允许应用程序快速适应不断变化的网络条件；它在快速数据中心网络中无法正常工作；它与网络内“中间箱”具有徒劳的，对抗性的关系。以APP为中心的运输（ACT）旨在解决这些问题。与当今的运输架构不同，ACT在做出传输决策时考虑了应用程序目标。 ACT使用计算机生成的传输控制程序，该程序采用工作负载的模型和目标自动合成协议。 该计划（REMY）既是实施协议的一种方式，也是一个设计工具，以回答有关拥塞控制的基本问题。 ACT探讨了对数据中心的传输和路径选择的集中控制，并使用机器学习分类器选择移动设备上的最佳网络。它旨在通过将中间箱插入视为多路径传输的概括来解决端点传输和网络内中间箱之间的争吵。项目参与者正在与Facebook和Google合作讨论其中一些想法。教育计划介绍了协议设计竞赛，学生可以通过跟踪数据运行并测量其协议，并在排行榜上比较其协议。
