The Internet is an essential part of modern society, playing a vital role in a wide range of educational, commercial, military, and social activities. However, network operators today have a limited ability to observe and control the paths used to carry traffic across the Internet. For example, although it is often beneficial for several networks to cooperate-e.g., a content provider and cellular network jointly picking the best paths from content to customers-existing Internet routing protocols make it difficult to share information or collaborate to select routes. These limitations contribute to a host of problems, including decreased path stability, degraded performance, and service outages. This project will develop a system called IN-CONTROL that aggregates information from participating networks and active measurements into an inter-domain network information base (iNIB). The iNIB presents operators with a unified interface for making observations about global forwarding paths and a rich control interface for issuing requests to steer traffic along preferred paths. To build the iNIB, the project is focusing on the following tasks: (i) developing provenance-based techniques to obtain reliable results from computations performed over potentially-untrustworthy data (ii) designing deployable mechanisms for observing and controlling Internet forwarding paths, and (iii) building a scalable implementation that incorporates optimizations to reduce resource demands for answering iNIB queries. The intellectual merit of this research lies in developing reliable abstractions for observing and controlling Internet forwarding paths and a scalable implementation that can be readily deployed on the current Internet. The broader impacts include reducing the fragility of the Internet, and broadening the interdisciplinary community of researchers working on problems related to inter-domain networking. This project also provides research experiences for undergraduate students and members of under-represented groups.

互联网是现代社会的重要组成部分，在各种教育，商业，军事和社交活动中发挥了至关重要的作用。但是，今天的网络运营商的观察和控制用于跨互联网流量的路径的能力有限。例如，尽管对于多个网络进行合作通常是有益的。这些限制导致了许多问题，包括降低路径稳定性，降级性能和服务中断。该项目将开发一个称为控制内部的系统，该系统将参与网络的信息汇总到主域间网络信息库（INIB）中。 INIB向操作员提供了一个统一的界面，用于观察全球转发路径和丰富的控制界面，以发出请求以沿着首选路径引导流量。为了构建INIB，该项目重点关注以下任务：（i）开发基于出处的技术，以从对潜在的无想数据数据（II）设计的计算中获得可靠的结果（II）设计可部署的机制，以观察和控制Internet转发路径，以及（III）可扩展的实施，以构建优化的实施，以构建资源需求，以减少回答资源的资源需求。这项研究的智力优点在于开发可靠的抽象来观察和控制Internet转发路径和可扩展的实现，可以很容易地在当前的Internet上部署。更广泛的影响包括降低互联网的脆弱性，并扩大研究与域间网络有关的问题的研究人员的跨学科社区。该项目还为本科生和代表性不足的群体的成员提供了研究经验。
