NBD: Dipzoom: A Global Ecosystem for Internet Measurements

互联网测量对于增强和管理互联网基础设施以及基于互联网的性能研究至关重要。然而，获得高质量的代表性测量仍然是一项艰巨的任务，需要相对较少拥有的专业知识和专业关系。本研究的目标是探索一种方法，以提供多样化、代表性和易于访问的按需互联网测量。具体来说，这个项目中的方法包括设计、原型制作和研究一个名为DipZoom的系统(用于？深度互联网性能放大？)，它基于两个关键思想。首先，DipZoom认识到任何一个供应商在建立一个代表互联网规模和多样性的平台时所面临的困难，因此实现了一种配对服务，使用P2P概念将需要测量的实验人员与外部测量提供商联系在一起。因此，DipZoom利用实验人员自己部署大量和各种各样的测量点。其次，DipZoom提供了整个测量提供商网络的统一视图，参与者可以访问和控制该视图。S本地机器。DipZoom无需再使用单独的测量探头，因此可以大大降低进行高质量互联网性能研究的门槛。本项目的智力价值在于上述思想以及这些思想所带来的一些新概念和技术，例如测量提供者的排名，测量主机的选择性校准，为给定测量选择测量主机，识别潜在攻击和制定对策等等。更广泛的影响包括为广泛的技术社区提供高质量的网络测量，并通过允许网络课程纳入复杂的网络测量实验来加强计算机网络的本科教育。

Internet measurements are crucial for enhancing and administering the Internet infrastructure as well as for grounded Internet performance research. Yet obtaining high quality representative measurements remains a daunting task, requiring expertise and professional connections that relatively few possess. The goal of this research is to explore an approach for providing diverse, representative, and easily accessible on-demand Internet measurements. Specifically, the approach in this project involves designing, prototyping, and studying a system named DipZoom (for ?Deep Internet Performance Zoom-in?), which is based on two key ideas. First, recognizing the difficulty any single provider would face in building a platform representative of the scale and diversity of the Internet, DipZoom implements a matchmaking service instead, using P2P concepts to bring together experimenters in need of measurements with external measurement providers. Thus, DipZoom leverages experimenters themselves in deploying a large number and variety of measuring points. Second, DipZoom provides a unified view over the entire network of measurement providers, which is accessible and controllable from a participant?s local machine. By removing the need to recruit and interact with individual measuring probes, DipZoom should drastically lower the barrier of entry for conducting quality Internet performance research. The intellectual merit of this project lies in the above ideas and in a number of new concepts and techniques these ideas entail, such as ranking of measurement providers, selective calibration of measuring hosts, selection of measuring hosts for a given measurement, identification of potential attacks and development of countermeasures, and so on. The broader impact includes making high-quality network measurements accessible to a wide technical community, and enhancing undergraduate education in computer networks by allowing networking courses to incorporate complex network measurement experiments.
