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.

域间路由是将整个互联网融合在一起的顶级协议。 对其鲁棒性，安全性和可管理性的基本改善将使依赖于当今互联网的任何人受益。边境网关协议（BGP）是Internet的标准管理人员路由协议，已被广泛认为是遭受许多基本问题，包括间歇性路由不可用；安全问题；管理头痛；最重要的是要解决这些挑战的困难。该项目旨在通过将BGP的工作置于云中，通过启用“域间路由为服务”来解决这一长期存在的问题，与当今的实践相比，这是一种根本不同的方法。该项目的目的是开发一个域间路由基础架构，该基础设施能够纳入事实上的域间路由功能以及研究人员或从业人员提出的增强功能，以解决BGP长期存在的问题。提出的方法是一种逻辑集中的域间路由体系结构，使运营商能够将BGP式路由计算卸载到云服务。对于企业网络，控制和管理的逻辑集中化已经取得了巨大的成功，因为软件定义的网络（SDN）方法的成功证明了控制和管理。但是，当今的界间路由在很大程度上没有被变革性的SDN趋势所触及的。该项目将对大约的设计，分析和实施和评估进行研究（这是一个逻辑集中的域间路由体系结构），该研究代表了今天通过将“薄客户端”路由器的工作卸载到云的方式来实施和管理BGP的基本范式转变。该项目中的技术研究推动力包括在互联网量表上证明大约在互联网量表上的可行性以及量化收益，例如收敛延迟的大幅减少，端到端可达性的改善，更具表现力的路由政策，什么IF分析能力以及提高了针对控制平面攻击的安全性。该项目将开发系统的开源原型，并通过研讨会和论坛吸引研究社区和网络运营商。该奖项反映了NSF的法定使命，并被认为是值得通过基金会的知识分子优点和更广泛的影响评估评估标准通过评估来获得支持的。
