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连接在一起的顶级协议。 其稳健性、安全性和可管理性的根本改进将使当今依赖互联网的任何人受益。边界网关协议 (BGP) 是互联网的标准提供商间路由协议，已被广泛认为存在许多基本问题，包括间歇性路由不可用；安全问题；管理难题；最重要的是应对这些挑战的困难。该项目旨在通过启用“域间路由即服务”将 BGP 的工作卸载到云端来解决此类长期存在的问题，这与当今的实践相比是一种截然不同的方法。该项目的目标是开发一个域间路由基础设施，该基础设施能够合并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功能，以解决 BGP 长期存在的问题。所提出的方法是逻辑上集中的域间路由架构，使运营商能够将 BGP 式路由计算卸载到云服务。软件定义网络 (SDN) 方法的成功证明了控制和管理的逻辑集中化在企业网络中取得了巨大成功；然而，今天的域间路由基本上没有受到变革性 SDN 趋势的影响。该项目将对 CIRCA（一种逻辑上集中的域间路由架构）的设计、分析、实施和评估进行研究，该架构通过卸载“瘦客户端”的工作，代表了当今 BGP 实施和管理方式的根本范式转变。 “路由器到云。该项目的技术研究重点包括展示 CIRCA 方法在互联网规模上的可行性，以及量化收益，例如显着减少收敛延迟、提高端到端可达性、更具表现力的路由策略、假设分析能力以及改进的路由策略。针对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参与。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
