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.

要了解互联网事件的影响 - 攻击，中断，性能退化或新部署的基础架构 - 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需要一张互联网使用的部分依赖于事件影响的网络，路线和服务器：互联网流量图：交通图将通过提供上下文来解释衡量结果并提出改善，从而改善所有人的互联网，从而为其他网络研究人员提供信息。互联网流量图还将帮助监管机构，政策制定者和经济学评估计算机科学之外的网络的社会影响。网络研究的十年研究已经研究了与----但不同于 - 但与 - - - 交通图相关的组件，包括自主系统（AS）和路由器级拓扑，Internet Exchange Points，Internet Exchange Points（IXPS），内容分配网络（CDN），一般交通型号和一般交通型。互联网服务提供商（ISP）和内容提供商对互联网流量图的一部分具有自己的高质量观​​点，但是业务和客户敏感性阻止了公众发布。该项目的目标是提供可共享的，可信赖的流量图。该地图流量将被量化 - 误差的估计值；广泛 - 完整性的估计；和可持续性 - 定期更新。该项目建议通过：•测量识别哪些网络托管Internet用户的流量图以及流行服务为流行服务部署服务器，用户和服务之间的路径以及这些路径上的相对活动水平。该地图必须从可复制的方法和开放数据中得出，以便可以共享。这样做将需要开发新技术。 •通过比较多种独立的方法和测试比较与准确但特权信息的测试比较来评估该地图的准确性，将建立对开源技术的信心。 •为研究社区和工具提供定期更新的地图，使其他人创建自己的地图。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估被认为是宝贵的支持。
