The evolution of network routers and switches has been driven primarily by performance. Recently, thanks in part to the emergence of large datacenter networks, the need for better control over network operations, and the desire for new features, programmability of routers has become as important as performance. In response, researchers and practitioners have developed reconfigurable switching chips with a RISC-inspired pipeline architecture, which provide some programmability through hardware primitives that can be configured into a processing pipeline with software directives. Reconfigurable switches are gaining traction as they perform the same as fixed-function chipsets but with lower area overhead. This project seeks to extend the state-of-the-art by developing higher-level programming abstractions and traffic management algorithms for reconfigurable switches. This project will investigate: 1) a C-like language and an abstract machine representing modern switches, 2) a compiler to convert the transactional specification to the pipelined abstract machine, and a 3) Push-In, First-Out (PIFO) primitive for programmable packet scheduling. This project will make programming high-speed switches easier and more expressive, which will be useful in datacenters, enterprises, and service provider networks. Research findings will be incorporated into the undergraduate and graduate curricula, offering students an opportunity to implement network protocols in C, a familiar language, but run them at hardware speeds. The course material will be made widely available through MIT OpenCourseWare and on the MITx MOOC.

网络路由器和开关的演变主要由性能驱动。最近，在一定程度上要归功于大型数据中心网络的出现，需要更好地控制网络操作以及对新功能的渴望，路由器的可编程性与性能一样重要。作为回应，研究人员和从业人员使用了RISC启发的管道体系结构开发了可重构的切换芯片，这些芯片通过硬件原始图提供了一些可编程性，可以​​通过软件指令将其配置为处理管道。可重新配置的开关的性能与固定功能芯片组相同，但面积较低。该项目旨在通过开发可重新配置开关的高级编程摘要和流量管理算法来扩展最先进的问题。该项目将调查：1）类似C的语言和代表现代开关的抽象计算机，2）一个编译器，将交易规范转换为管道的抽象机器，以及A 3）用于可编程数据包计划的推送，首先输出（PIFO）原始版本。该项目将使编程高速开关更加容易，更具表现力，这将在数据中心，企业和服务提供商网络中有用。研究发现将纳入本科和研究生课程中，为学生提供一个在C（一种熟悉的语言）中实施网络协议的机会，但以硬件速度运行它们。该课程材料将通过MIT OpenCourseware和MITX MOOC广泛使用。
