Tor是用于实现在线匿名和抵制审查的最广泛使用的隐私增强技术之一。同时，Tor也是一个不断发展的研究网络，研究人员在其上进行实验，以提高网络对攻击的弹性并提高其性能。现有的研究Tor的方法包括分析建模、模拟、小规模网络仿真、小规模PlanetLab部署以及实时Tor网络的测量和分析。尽管关于Tor的工作越来越多，但没有一种被广泛接受的方法来进行Tor研究，以保持现实主义，同时保护实时用户的隐私。为了提出一个标准的、严格的实验框架，以确保安全和现实的方式进行Tor研究，我们提出了一个大型Tor网络仿真工具包和测试平台ExperimentTor的设计。我们还报告了我们的早期经验，目前部署在四个研究机构的原型试验台。
Tor is one of the most widely-used privacy enhancing technologies for achieving online anonymity and resisting censorship. Simultaneously, Tor is also an evolving research network on which investigators perform experiments to improve the network's resilience to attacks and enhance its performance. Existing methods for studying Tor have included analytical modeling, simulations, small-scale network emulations, small-scale PlanetLab deployments, and measurement and analysis of the live Tor network. Despite the growing body of work concerning Tor, there is no widely accepted methodology for conducting Tor research in a manner that preserves realism while protecting live users' privacy. In an effort to propose a standard, rigorous experimental framework for conducting Tor research in a way that ensures safety and realism, we present the design of ExperimenTor, a large-scale Tor network emulation toolkit and testbed. We also report our early experiences with prototype testbeds currently deployed at four research institutions.
