Ninety-nine percent of all international data is carried by a fiber cable network at the bottom of the world’s oceans. This submarine cable network (SCN) consists of hundreds of cables stretching over 1 million kilometers, connects nearly every region in the world, serves as the operational backbone of global services, and closes connectivity gaps in the world’s underserved areas. Yet, despite its impressive scale, very little is known about the SCN’s broader characteristics and its role in the global Internet. This collaborative project brings together researchers from Northwestern University and the University of Wisconsin, Madison to develop a thorough understanding of the criticality of the submarine cable network in context. This research effort will: (1) define a methodology for the analysis of the SCN criticality across regions, applications, and uses, (2) design and build a SCN observatory that embodies this methodology, and (3) conduct analyses of criticality in a range of contexts from country-specific to third-party service dependencies to environmental threats. The goals of this work are to advance the foundational understanding of the SCN and to create data sets, metrics, methods, and tools that will enhance performance, robustness, and manageability.An improved understanding of the SCN and its critical role in the public Internet has a broad interest, from the millions of users that rely on these systems for their social, political, economic, and media exchanges, to the policymakers, regulators, operators, and entities that decide on new infrastructure deployment. The tools developed and the data we collect over the course of this project will be made available to the community. The findings, techniques, and tools developed in this project, including related course materials, will be made available at https://www.cs.aqualab.edu/projects/Critical-SCN. The site will be maintained for at least one year past the ending of the project.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.

百分之九十九的国际数据是由世界海底的光缆网络承载的。这个海底光缆网络 (SCN) 由数百条电缆组成，绵延超过 100 万公里，几乎连接世界上每个地区，提供服务。作为全球服务的运营支柱，并缩小了世界服务欠缺地区的连接差距，尽管其规模令人印象深刻，但人们对 SCN 的更广泛特征及其在全球互联网中的作用知之甚少。西北大学和威斯康星大学麦迪逊分校将深入了解海底电缆网络的关键性，这项研究工作将：(1) 定义一种跨区域、应用和用途分析 SCN 关键性的方法。 ，（2）设计和建立一个体现这种方法的 SCN 观测站，以及（3）在从特定国家到第三方服务依赖到环境威胁的一系列背景下进行关键性分析。这项工作的目标是推进。的基本理解SCN 并创建可增强性能、稳健性和可管理性的数据集、指标、方法和工具。对 SCN 及其在公共互联网中的关键作用的深入了解引起了数百万依赖 SCN 的用户的广泛兴趣这些系统用于社会、政治、经济和媒体交流，供决策者、监管者、运营商和决定新基础设施部署的实体使用。我们在该项目过程中开发的工具和收集的数据将提供给决策者、监管者、运营商和实体。社区开发的发现、技术和工具。该项目的内容，包括相关课程材料，将在 https://www.cs.aqualab.edu/projects/Critical-SCN 上提供。该网站将在项目结束后至少保留一年。授予 NSF 的法定使命，并通过评估反映使用基金会的智力优点和更广泛的影响审查标准，被认为值得支持。
