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.

新颖的技术（例如软件定义的网络）正在通过对路由器行为进行灵活的控制来改变网络格局。 然而，互联网的间路由体系结构需要在域之间进行协调，仍然陷入僵化。 的确，互联网架构的许多关键缺点 - 包括不可靠，效率低下的资源分配和不安全感 - 可以很大程度上归因于不灵活的路由。 Internet的BGP和IP协议仅提供到每个目的地的一条路径，并且此路径可能会被打破，效率低下或不安全。此项目正在开发一种方法，以使Internet的路由和转发体系结构具有灵活性。 为了突破当前不灵活的路由的登录，该项目正在推进源控制的路由（SCR），作为一种架构方法，可以从根本上启用更灵活的路由。路由决策不是将路由决策嵌入到网络中，而是在源中选择的网络的参数，即用户的设备或代表其行动的网络。该灵活性为多个问题提供了解决方案，包括可靠性，性能和免受某些交通吸引力攻击的保护。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;和可扩展性。 首先，尽管过去的SCR体系结构为用户提供了路线控制，但他们从网络所有者和运营商那里获得了控制。 关键需求是体系结构中的“策略灵活性”，以启用SCR而不限制网络所有者的控制。 该项目正在开发一种正式的政策灵活性理论，并设计了实现高政策灵活性的体系结构。其次，该项目正在量化SCR体系结构对拒绝服务攻击的脆弱性和开发技术以限制最严重的案例损害攻击者可能造成的。 第三，该项目正在开发用于以可扩展方式利用灵活路由的技术，改善了Internet通信的延迟和可靠性。Broader的影响。该项目的结果将是理论基础，设计和实施的Internet体系结构，这些互联网体系结构为当今的Internet带来了最重要的挑战，包括当今的互联网 - 可靠性，包括可靠性，包括可靠性。 该项目的理论基础研究方法，包括新颖的协议灵活性理论，将通过开发研究生级的“计算机网络理论”课程和调查论文来与教育进行整合。结果将通过出版物，演示文稿和公共软件发布来传播。
