项目摘要

Novel technologies such as software defined networking are changing the networking landscape by giving individual domains (such as ISPs) flexible control over their routers' behavior. Yet the Internet's interdomain routing architecture, which requires coordination among domains, remains mired in inflexibility. Indeed, many of the key shortcomings of the Internet's architecture --- including unreliability, inefficient resource allocation, and insecurity --- can be attributed in large part to inflexible routing. The Internet's BGP and IP protocols offer only a single path to each destination, and this path may be broken, inefficient, or insecure.This project is developing an approach to bring flexibility to the Internet's routing and forwarding architecture. To break through the current logjam of inflexible routing, the project is advancing source-controlled routing (SCR) as an architectural approach to enable fundamentally more flexible routing. Rather than embedding the routing decisions within the network, routing decisions are a parameter to the network chosen at the source, i.e., the user's device or one acting on its behalf. That flexibility yields solutions to multiple problems, including reliability, performance, and protection from certain traffic attraction attacks.To achieve a viable SCR architecture, the project is solving three key challenges: policy flexibility of the core architecture; security; and scalability. First, while past SCR architectures gave route control to users, they took away control from network owners and operators. The key need is "policy flexibility" in the architecture, to enable SCR without limiting network owners' control. The project is developing a formal theory of policy flexibility and designing an architecture which achieves high policy flexibility. Second, the project is quantifying the vulnerability of SCR architectures to denial-of-service attacks and developing techniques to limit the worst-case damage attackers can inflict. Third, the project is developing techniques for sources to utilize flexible routing in a scalable way, improving latency and reliability of Internet communications.Broader Impact.The result of this project will be the theoretical foundations, design, and implementation of an Internet architecture that offers significant gains to areas which are the most critical challenges for the Internet today --- including reliability, performance, and security. The project's theoretically-grounded research methodology, including a novel theory of protocol flexibility, will be integrated with education via development of material for a graduate-level "Theory of Computer Networks" course and survey papers. Results will be disseminated through publications, presentations, and a public software release.
软件定义网络等新技术通过赋予各个域(如isp)对其路由器行为的灵活控制,正在改变网络格局。然而,互联网的域间路由体系结构,需要域之间的协调,仍然陷入缺乏灵活性的困境。实际上,Internet架构的许多主要缺点——包括不可靠性、低效的资源分配和不安全性——在很大程度上可以归因于不灵活的路由。Internet的BGP和IP协议只提供到每个目的地的一条路径,这条路径可能是断裂的、低效的或不安全的。这个项目正在开发一种方法,为互联网的路由和转发架构带来灵活性。为了突破当前不灵活路由的僵局,该项目正在推进源控制路由(SCR)作为一种架构方法,从根本上实现更灵活的路由。路由决定不是在网络中嵌入路由决定,而是在源处选择网络的一个参数,即用户的设备或代表其运行的设备。这种灵活性可以解决多种问题,包括可靠性、性能和防止某些流量吸引攻击。为了实现可行的SCR架构,该项目正在解决三个关键挑战:核心架构的政策灵活性;安全;和可伸缩性。首先,虽然过去的SCR架构将路由控制权交给了用户,但它们剥夺了网络所有者和运营商的控制权。关键需求是架构中的“策略灵活性”,在不限制网络所有者控制的情况下启用SCR。该项目正在开发一个政策灵活性的正式理论,并设计一个实现高政策灵活性的体系结构。其次,该项目正在量化SCR架构对拒绝服务攻击的脆弱性,并开发技术来限制攻击者可能造成的最坏情况。第三,该项目正在为资源开发技术,以可扩展的方式利用灵活的路由,改善互联网通信的延迟和可靠性。更广泛的影响。该项目的结果将是互联网架构的理论基础、设计和实现,为当今互联网面临的最关键挑战(包括可靠性、性能和安全性)领域提供重大收益。该项目以理论为基础的研究方法,包括一种新的协议灵活性理论,将通过开发研究生水平的“计算机网络理论”课程和调查论文的材料与教育相结合。结果将通过出版物、演示文稿和公开软件发布来传播。
