CI-ADDO-EN: ILENS: Internet Laboratory for Empirical Network Science

了解互联网拓扑、路由、工作负载、性能和漏洞的结构和动态仍然令人不安地难以捉摸，部分原因是科学研究人员缺乏大规模的分布式网络测量基础设施。该项目在地理范围和功能上升级和扩展了主动测量仪器(ARK)，创建了一个前所未有的实验室，在其中可以通过广泛分布的专用监视器轻松设计、实施和协调执行互联网测量实验。2007年，方舟发起了一项新的全球互联网拓扑测量和测绘考察，现在收集了学术研究人员可用的最大一组IP拓扑数据。我们使用最好的IP拓扑映射技术，共享原始和处理后的数据集，并支持软件对生成的图形进行分析、注释、拓扑生成和交互式可视化。这项工作有三项任务：(1)在缺乏覆盖的地理和拓扑区增加新的监视器；(2)改进处理拓扑数据的工具；(3)增强和开发软件模块，以支持新的实验和验证。还将举办研讨会，收集、综合和整合对方舟行动的反馈。预计将有更多的研究团体继续使用这一计量基础设施。通过降低实施科学互联网测量实验的成本，方舟公司将允许研究人员测试和评估更雄心勃勃、更复杂和更有风险的想法。产生的数据将支持广泛的网络建模、模拟、分析和理论研究活动，包括历史互联网研究和对拟议的未来互联网架构的评估。

Understanding the structure and dynamics of Internet topology, routing, workload, performance, and vulnerabilities remains disturbingly elusive, in part for lack of large-scale distributed network measurement infrastructure available to scientific researchers. This project upgrades and extends -- in geographic scope as well as function -- an active measurement instrumentation (Ark), creating an unprecedented laboratory in which to easily design, implement, and coordinate execution of Internet measurement experiments across a widely distributed set of dedicated monitors. In 2007 Ark launched a new global Internet topology measurement and mapping expedition, and now gathers the largest set of IP topology data available to academic researchers. We use the best available techniques for IP topology mapping, share raw and processed data sets, and support software for analysis, annotation, topology generation, and interactive visualization of resulting graphs. The effort has three tasks: (1) adding new monitors in geographic and topological areas lacking coverage; (2) improving tools for processing topology data; (3) enhancing and developing software modules to support new experiments and validation. Workshops will also be conducted to collect, synthesize, and integrate feedback on Ark operations. It is expected that a broad set of research communities will continue make use of this measurement infrastructure. By lowering the cost to implement scientific Internet measurement experiments, Ark will allow researchers to test and evaluate more ambitious, sophisticated and risky ideas. The resulting data will enable a wide range of network modeling, simulation, analysis, and theoretical research activities, including historical Internet studies and evaluation of proposed future Internet architectures.
