CAREER: Next-Generation Active Internet Measurement

研究人员、企业和政府使用各种各样的技术来快速绘制互联网地图并了解其行为方式。探索这些行为可以让我们了解诸如组织和政府如何控制全球人们可以访问的网站或网络如何受到攻击之类的事情。不幸的是，目前的技术主要集中在如何快速和多少的互联网可以探索，这是非常具有挑战性的，以确保我们的理解是完整和正确的。该项目将创建下一代互联网测量技术，通过更好地理解网络的结构和连接、临时行为和测量结果，提高测量的正确性和完整性。开发下一代互联网测量需要了解全球网络运营商复杂的现实世界行为。该项目有三个重点。首先，该项目将探索和开发方法，以了解路由如何影响全球路径测量，重点是互联网审查。其次，该项目将探索和开发理解路由如何影响端到端路径测量的方法，重点关注延迟、非确定性和完整性，重点是整个互联网扫描技术。第三，该项目将开发许多开源工具和数据集，以促进下一代路径感知主动互联网测量。互联网测量被用于一系列任务，从影响政府政策，识别罪犯和国家支持的攻击，到了解天气导致的网络故障。该项目的方法、数据集和工具促进了主动互联网测量的正确性，这将使研究人员、行业从业者、政策制定者和政府能够更有效、更正确地实现这些不同的目标。此外，该项目将建立一个以社区大学为重点的衔接项目，旨在为社区大学转学生在研究型大学的成功经验做好准备，同时也为他们提供网络和安全研究的机会。这个综合衔接课程将提高转学生成功升入研究生院的可能性。有关该项目的其他信息，包括所有研究论文、数据集、代码、存储库、工具、结果和外展活动，可在该项目的网站上找到：https://cc.gatech.edu/~pearce/career/。该网站将在项目完成后至少维持5年。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

Researchers, businesses, and governments use a variety of technologies to quickly map the Internet and understand how it behaves. Exploring these behaviors lets us understand things such as how organizations and governments control what websites people globally can visit or how networks are attacked. Unfortunately, current technologies largely concentrate on how quickly and how much of the Internet can be explored, and it is very challenging to ensure our understanding is complete and correct. This project will create the next generation of Internet measurement technologies that will improve measurement correctness and completeness by better understanding the structure and connections of networks, temporary behaviors, and the results of measurements. Developing next-generation Internet measurement requires understanding the complex real-world behavior of network operators around the globe. The project has three thrusts. First, the project will explore and develop methods to understand how routing impacts on-path measurements, globally, with an emphasis on Internet censorship. Second, the project will explore and develop methods understanding how routing impacts end-to-end in-path measurements, focusing on latency, non-determinism, and completeness, with an emphasis on whole-Internet scanning technologies. Third, the project will develop numerous open-source tools and datasets to facilitate the next-generation of path-aware active Internet measurement. Internet measurement is used for a range of tasks from influencing government policy, to identifying criminals and state-sponsored attacks, to understanding weather-induced network failures. The correctness of active Internet measurements facilitated by the methodologies, datasets, and tools from this project will enable researchers, industry practitioners, policy makers, and governments to more effectively and correctly achieve these diverse goals. Furthermore, this project will establish a community college-focused pathways program aimed at the dual goals of preparing community college transfer students for a successful experience at a research university, while also providing them network and security research opportunities. This integrated pathways program will improve the likelihood of transfer student's successful progression to graduate school.Additional information about the project, including all research papers, datasets, code, repositories, tools, results, and outreach activities can be found on the project's website: https://cc.gatech.edu/~pearce/career/. The website will be maintained for a period of at least 5 years after completion of the project.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.
