Interdomain routing is the top-level protocol that holds the entire Internet together. Fundamental improvements to its robustness, security, and manageability will benefit anyone who relies on the Internet today. The Border Gateway Protocol (BGP), the Internet's standard inter-provider routing protocol, has been widely recognized as suffering from a number of fundamental problems including intermittent routing unavailability; security problems; management headaches; and most importantly difficulty evolving to meet these challenges. This project seeks to address such long-standing problems by offloading BGP's work to the cloud by enabling 'interdomain routing as a service', a radically different approach compared to today's practice. The goal of this project is to develop an interdomain routing infrastructure that is capable of incorporating de facto interdomain routing capabilities as well as enhancements proposed by researchers or practitioners to address BGP's long-standing problems. The proposed approach is a logically centralized interdomain routing architecture that enables operators to offload BGP-style route computation to a cloud service. Logical centralization of control and management has been enormously successful for enterprise networks as evidenced by the success of software-defined networking (SDN) approaches; however, interdomain routing today is largely untouched by the transformative SDN trend. The project will conduct research on the design, analysis, and implementation and evaluation of CIRCA -- a logically centralized interdomain routing architecture -- that represents a fundamental paradigm shift in the way BGP is implemented and managed today by offloading the work of "thin client" routers to the cloud. The technical research thrusts in the project include demonstrating the feasibility of the CIRCA approach at Internet scales and quantifying benefits such as significant reduction in convergence delays, improved end-to-end reachability, more expressive routing policies, what-if analysis capabilities, and improved security against control plane attacks. The project will develop a systematic open-source prototype and engage the research community and network operators through workshops and forums.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

域间路由是将整个Internet连接在一起的顶级协议。 从根本上改进其健壮性、安全性和可扩展性将使今天依赖互联网的任何人受益。边界网关协议（BGP），互联网的标准供应商间路由协议，已被广泛认为是遭受了一些基本的问题，包括间歇性路由不可用;安全问题;管理头痛;最重要的是难以发展，以满足这些挑战。该项目旨在通过启用“域间路由即服务”将BGP的工作卸载到云来解决这些长期存在的问题，这是一种与当今实践截然不同的方法。该项目的目标是开发一个域间路由基础设施，能够将事实上的域间路由功能，以及研究人员或从业者提出的增强，以解决BGP的长期存在的问题。所提出的方法是一个逻辑上集中的域间路由架构，使运营商能够卸载BGP风格的路由计算到云服务。控制和管理的逻辑集中化在企业网络中取得了巨大的成功，软件定义网络（SDN）方法的成功就证明了这一点;然而，今天的域间路由在很大程度上没有受到变革性SDN趋势的影响。该项目将对CIRCA的设计、分析、实施和评估进行研究，CIRCA是一种逻辑集中的域间路由架构，通过将“瘦客户端”路由器的工作卸载到云端，代表了BGP实施和管理方式的根本范式转变。该项目的技术研究重点包括证明CIRCA方法在互联网规模上的可行性，并量化其好处，例如显著减少收敛延迟，提高端到端可达性，更具表现力的路由策略，假设分析功能以及提高控制平面攻击的安全性。该项目将开发一个系统的开源原型，并通过研讨会和论坛吸引研究界和网络运营商。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
