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.

无法将核心功能更改为简单的数据包转发服务，从而阻碍了Internet的创新。 尽管互联网的建筑简单性很可能导致了其巨大的成功，但它也带来了意想不到的后果。 例如，几乎没有固有的支持来衡量和监视互联网，这使得管理层具有挑战性，并使人们对互联网的结构和行为有深刻的了解。 此外，实时应用程序通常依靠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隔离系统，以检测和响应攻击；如果有协调的检测和响应机制与Internet不可或缺的功能：该项目开发了一种增强Internet路由器功能的新方法，以实现实现未来应用和服务的开发，则可以更有效地检测和应对安全威胁。 该研究的目的是在路由器和类似的互联网设备上提供可编程的机制，以使服务提供商，应用程序开发人员和研究人员能够利用网络内的功能。 将基于原始功能开发用于编程网络路由器的新框架，该功能能够在Internet中启用和公开新的和有用的功能。 这些原语将旨在为互联网，实时应用程序和网络安全的测量和监视提供网络内支持。BRODERIMPACT：将公开向研究人员提供参考设计和编程框架的参考设计和实施，并在网络创新（GENI）实验网络的全球环境中进行部署和评估。 在这种情况下，研究人员将能够使用它来测试需要或可能从其他网络内功能中受益的研究思想。 此外，将举行教程将研究人员介绍到系统中。本科生将参加该项目的研究活动。 此外，将开发和量身定制新的课程材料，并在较小的机构的本科生中进行量身定制。 将开发两组课程：一组：一组可与流行的可重构硬件系统（NETFPGA）一起使用，另一组可用于开发的路由器编程框架。教育材料将公开向其他本科机构公开提供，将举行讲习班，以将材料传播给教育社区。
