A Platform for Internet InnovationThe architectural stability of the Internet was crucial in fostering the development of new applications and networking technologies by giving the former a stable base upon which to build and giving the latter a fixed set of requirements to support. However, in recent years this architectural stability has become a liability, as there are areas of increasing importance ? most notably inadequate support of security and availability, lack of adequate mechanisms for privacy, mobility, middleboxes, and data-oriented functionality ? where the original Internet architecture falls short. The persistence of the Internet's architectural deficiencies is not because they are intellectually intractable, but because they are beyond the reach of incrementally deployable changes. Based on this observation, the research team takes a different approach than recent clean-slate designs, focusing not on a new fixed architecture but instead on providing a platform to enable architectural innovation through incrementally deployable changes, without massive disruption in the infrastructure. In this research project, the research team focuses on the ?hardware-defined functionality? challenge and proposes a ?platform for innovation? that allows the network infrastructure to support new architectures without changes to the underlying hardware. In particular, this approach will enable forwarding hardware to support a wide range of alternative designs. In addition, so that changes can be introduced alongside the current design, hardware will also be able to support multiple designs simultaneously. The proposed platform will use a newly developed paradigm called Software-Defined Networks (SDN), currently embodied in the OpenFlow and NOX projects. OpenFlow is an open hardware forwarding interface. NOX is an open-source software platform that provides global abstractions to network management software and in turn communicates the decisions made by this software to the individual forwarding boxes. This effort will provide a solid foundation for more general SDN designs that are open, comprehensive and can meet long-term needs. The research team will also explore and demonstrate applicability of the SDN approach including abstractions and programming model for different domains of network use. These include enterprise, WAN, home, and wireless. To demonstrate the ability of the proposed platform to support innovation in radically new network mechanisms, the research team will deploy prototype novel architectures on SDN. If successful, the proposed approach would allow the use of known approaches and design proposals currently available in the literature to address many of the Internet's current problems, as these solutions would be incrementally deployable, without major disruption to the underlying infrastructure. Furthermore, current commercial efforts to address Internet?s deficiencies are disjointed, proprietary, and tailored for short-term needs. The next generation of SDN technology provides a solid basis for coordinated, long-term efforts to address critical needs in areas of security, mobility and support of content-centric application and services. More importantly, the proposed approach would allow the Internet to meet future requirements as they arise through incrementally deployable modifications, relieving network designers of the burden of predicting what these future requirements might be.

互联网创新平台互联网架构的稳定性对促进新应用程序和网络技术的发展至关重要，因为它为前者提供了一个稳定的基础，并为后者提供了一套固定的需求来支持。然而，近年来，这种体系结构的稳定性已经成为一种负担，因为有越来越重要的领域。最明显的是对安全性和可用性的支持不足，缺乏足够的隐私、移动性、中间盒和面向数据功能的机制？在这方面，最初的互联网架构有所不足。Internet架构缺陷的持续存在并不是因为它们在智力上难以解决，而是因为它们超出了增量可部署更改的范围。基于这一观察，研究团队采用了一种不同于最近的全新设计的方法，不关注新的固定架构，而是提供一个平台，通过增量可部署的更改来实现架构创新，而不会对基础设施造成大规模破坏。在这个研究项目中，研究团队重点研究了？hardware-defined功能?挑战并提出？创新平台？这使得网络基础设施能够支持新的体系结构，而无需更改底层硬件。特别是，这种方法将使转发硬件能够支持广泛的替代设计。此外，为了在当前设计的基础上进行更改，硬件也将能够同时支持多种设计。拟议的平台将使用一种名为软件定义网络（SDN）的新开发范例，该范例目前体现在OpenFlow和NOX项目中。OpenFlow是一个开放的硬件转发接口。NOX是一个开源软件平台，它为网络管理软件提供全局抽象，并反过来将该软件做出的决策传达给各个转发框。这一努力将为更通用的SDN设计提供坚实的基础，这些设计是开放的，全面的，可以满足长期需求。研究小组还将探索和演示SDN方法的适用性，包括针对不同网络使用领域的抽象和编程模型。这些包括企业、WAN、家庭和无线。为了证明所提出的平台支持全新网络机制创新的能力，研究团队将在SDN上部署新型原型架构。如果成功，所建议的方法将允许使用文献中目前可用的已知方法和设计建议来解决Internet当前的许多问题，因为这些解决方案将是可增量部署的，而不会对底层基础设施造成重大破坏。此外，目前针对互联网的商业努力？S缺陷是脱节的、专有的，并且是为短期需求量身定制的。下一代SDN技术为协调一致的长期努力提供了坚实的基础，以解决安全、移动性和支持以内容为中心的应用和服务领域的关键需求。更重要的是，所建议的方法将允许Internet通过增量可部署的修改来满足未来的需求，从而减轻网络设计人员预测这些未来需求的负担。
