The inability to change core functionality beyond a simple packet forwarding service has hindered innovation in the Internet. Although the architectural simplicity of the Internet has likely led to its massive success, it has also had unintended consequences. For example, there is little intrinsic support to measure and monitor the Internet, which makes effective management challenging and has confounded efforts to gain a deep understanding of the Internet's structure and behavior. In addition, real-time applications often rely on overlay networks and application-level optimizations to deliver acceptable performance to users. Moreover, various network security devices are deployed as extrinsic, isolated systems to detect and respond to attacks; methods to detect and react to security threats could be much more effective if there were coordinated detection and response mechanisms integral to the Internet.Intellectual Merit: This project develops a new approach for enhancing the functionality of Internet routers, toward the goal of enabling the development of future applications and services. The aim of the research is to provide programmable mechanisms on routers and similar Internet devices to enable service providers, application developers, and researchers to harness in-network capabilities. A new framework for programming network routers will be developed based on primitive functions that enable and expose new and useful capabilities in the Internet. These primitives will be designed to provide in-network support for measurement and monitoring of the Internet, real-time applications, and network security.Broader Impact: A reference design and implementation of the programming framework will be made openly available to researchers and deployed and evaluated in the Global Environment for Network Innovations (GENI) experimental network. In this setting, researchers will be able to use it to test research ideas that require or could benefit from additional in-network capabilities. In addition, tutorials will be held to introduce researchers to the system. Undergraduate students will participate in the research activities of this project. Moreover, new course materials will be developed and tailored to undergraduates at smaller institutions. Two sets of coursework will be developed: one for use with a popular reconfigurable hardware system (the NetFPGA) and another for use with the router programming framework to be developed. The educational materials will be made openly available to other undergraduate institutions and workshops will be held to disseminate the materials to the educational community.

除了简单的数据包转发服务之外，无法改变核心功能，这阻碍了互联网的创新。 尽管互联网架构的简单性可能带来了巨大的成功，但它也产生了意想不到的后果。 例如，衡量和监控互联网的内在支持很少，这使得有效管理具有挑战性，并且阻碍了深入了解互联网结构和行为的努力。 此外，实时应用程序通常依赖覆盖网络和应用程序级优化来为用户提供可接受的性能。 此外，各种网络安全设备被部署为外部的、孤立的系统来检测和响应攻击；如果互联网中存在集成的协调检测和响应机制，检测和应对安全威胁的方法可能会更加有效。智力优点：该项目开发了一种增强互联网路由器功能的新方法，以实现促进发展的目标未来的应用程序和服务。 该研究的目的是在路由器和类似互联网设备上提供可编程机制，使服务提供商、应用程序开发人员和研究人员能够利用网络内功能。 将基于原始函数开发用于网络路由器编程的新框架，这些函数在互联网中启用和公开新的有用的功能。 这些原语旨在为互联网、实时应用程序和网络安全的测量和监控提供网络内支持。更广泛的影响：编程框架的参考设计和实现将向研究人员开放，并进行部署和部署在全球网络创新环境（GENI）实验网络中进行了评估。 在这种情况下，研究人员将能够使用它来测试需要或可能受益于额外网络内功能的研究想法。 此外，还将举办教程向研究人员介绍该系统。本科生将参与本项目的研究活动。 此外，将为小型机构的本科生开发和定制新的课程材料。 将开发两套课程：一套用于流行的可重构硬件系统（NetFPGA），另一套用于将要开发的路由器编程框架。这些教育材料将向其他本科院校公开提供，并将举办研讨会向教育界传播这些材料。
