Collaborative Research: CNS Core: Medium: A Traffic Map for the Internet

要了解互联网事件（攻击、中断、性能下降或新部署的基础设施）的影响，必须了解它们如何影响人们对互联网服务的使用。研究人员、网络和服务运营商、监管机构、政策制定者和经济学家需要一张地图，说明互联网使用的哪些部分取决于受事件影响的网络、路线和服务器：互联网流量地图。这样的流量地图将通过提供背景信息来解释测量结果和提出的改进建议，从而为其他网络研究人员提供信息，最终有助于改善每个人的互联网。互联网流量地图还将帮助监管机构、政策制定者和经济学家评估计算机科学之外的网络对社会的影响。数十年的网络研究已经研究了与流量地图相关但又不同的组件，包括自治系统 (AS) 和路由器级拓扑、互联网交换点 (IXP)、内容分发网络 (CDN) 部署和通用流量矩阵。 互联网服务提供商 (ISP) 和内容提供商对自己的互联网流量地图部分拥有自己的高质量视图，但商业和客户敏感性阻止公开发布。该项目的目标是提供可共享、可信的交通地图。该地图流量将被量化——并带有误差估计；广泛——具有完整性估计；且可持续——定期更新。 该项目建议通过以下方式满足这一需求： • 测量流量图，识别哪些网络承载互联网用户、流行服务在何处部署流行服务服务器、用户和服务之间的路径以及这些路径上的相对活动级别。 该地图必须源自可复制的方法和开放数据，以便可以共享。这样做需要开发新技术。 • 通过比较多种独立方法并根据外部信息进行测试来评估该图的准确性。 与准确但特权信息的比较将建立对开源技术的信心。 • 向研究界提供定期更新的地图以及允许其他人创建自己的地图的工具。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。

To understand the impact of Internet events---attacks, outages, degraded performance, or newly deployed infrastructure---one must understand how they affect peoples' use of Internet services. Researchers, network and service operators, regulators, policy makers, and economists need a map of what portion of Internet use depends on the networks, routes, and servers impacted by the events: an Internet traffic map.Such a traffic map will inform other networking researchers by providing context to interpret measurement results and proposed improvements, ultimately contributing to improving the Internet for everyone. An Internet traffic map will also help regulators, policy makers, and economists assess the societal impact of networking outside computer science.Decades of network research have studied components related to---but distinct from---a traffic map, including the autonomous system (AS) and router-level topologies, Internet exchange points (IXPs), content distribution network (CDN) deployments, and general traffic matrices. Internet service providers (ISPs) and content providers have their own, high-quality views of their part of the Internet traffic map, but business- and customer-sensitivities prevent public release. This project’s goal is to provide a sharable, trusted traffic map. This map traffic will be quantified—with estimates of error; broad—with estimates of completeness; and sustainable—with regular updates. This project proposes to meet this need by:• Measuring a traffic map that identifies which networks host Internet users and where popular services deploy servers for popular services, the paths between users and services, and relative activity levels on those paths. This map must be derived from replicable approaches and open data so it can be shared. Doing so will require developing new techniques. • Evaluating the accuracy of this map by comparing multiple, independent methods, and testing against external information. Comparison against accurate but privileged information will establish confidence in open-source techniques. • Providing regularly-updated maps to the research community and tools that allow others to create their own maps.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.
