A fundamental question in the net neutrality debate is the extent to which network operators should be allowed to discriminate among Internet packet streams. Unfortunately, the state of affairs in reality has dramatically surpassed academic debating at various levels. Rough competition among Internet service and content providers, as well as huge monopoly potentials, are radically increasing the scale of discriminatory acts in the Internet. The principal investigator (PI) will build Internet Audit: a system capable of monitoring network or content delivery network (CDN) services and elements, revealing their behavior and policies, and accurately detecting and exposing biased or discriminatory network practices. The research efforts will be focused on devising novel distributed end-host-based auditing methodologies and tools. The PI will systematically study a number of threat models, ranging from open DoS attacks to more sophisticated methods in which ISPs are adding jitter or using differentiated services in destructive ways. Intellectual Merit: This research will address fundamental questions that are key to developing and deploying the Internet Audit services. The researcher will apply elements of the info-gap decision theory to devise and evaluate novel monitoring algorithms and enable the Internet Audit effectively operate in uncertain Internet environments. Broader Impact: By enabling clients to know how ISPs and CDNs behave, the auditing system will enable fair competition, preclude monopolies, oligopolies, or collusions, eventually helping clients get better services at fair prices. By exposing discriminatory network behavior, the system will help reduce the alarming scale of discriminating acts happening in today's Internet, ultimately facilitating the development of free and open society.

网络中立性辩论中的一个基本问题是网络运营商应该在多大程度上被允许区分互联网数据包流。不幸的是，现实中的事态已经大大超过了各级学术辩论。互联网服务和内容提供商之间的激烈竞争，以及巨大的垄断潜力，正在从根本上增加互联网上歧视行为的规模。首席研究员（PI）将建立互联网审计：一个能够监控网络或内容交付网络（CDN）服务和元素的系统，揭示其行为和政策，并准确检测和揭露有偏见或歧视性的网络做法。研究工作将集中在设计新的分布式基于终端主机的审计方法和工具。PI将系统地研究一些威胁模型，从开放式DoS攻击到更复杂的方法，其中ISP正在以破坏性的方式添加抖动或使用差异化服务。智力优势：这项研究将解决开发和部署互联网审计服务的关键的基本问题。研究者将应用资讯缺口决策理论的元素，设计和评估新的监控算法，使互联网审计在不确定的互联网环境中有效地运作。更广泛的影响：通过让客户了解ISP和CDN的行为，审计系统将实现公平竞争，排除垄断、寡头垄断或串通，最终帮助客户以公平的价格获得更好的服务。通过揭露歧视性网络行为，该系统将有助于减少当今互联网上发生的令人震惊的歧视行为，最终促进自由和开放社会的发展。
