项目摘要

The spread of COVID-19 has led to unprecedented and ongoing changes to daily life, including shelter-in-place orders, widespread closing of businesses and schools, and work-from-home and school-from-home at previously unknown levels. These changes in behavior are placing extraordinary demands on the Internet. This project will measure the Internet’s ability to meet these demands, including comparing its performance before, during, and after the peak of COVID-19; whether the amount of change varies between areas heavily impacted by COVID-19 and those less impacted; and whether and how large networks adapt.To provide this rich understanding, this project will combine multiple Internet-scale datasets that provide complementary views to investigate how responses to COVID-19 have impacted the Internet and how networks have reacted. Specifically, the project will measure how workloads have changed and their impact on networks in response to COVID-19 by measuring traffic patterns worldwide and the impact of congestion on performance globally. In addition, the project will measure how networks react to these changes in workloads by monitoring path changes that indicate rerouting of traffic during surges induced by measures in response to COVID-19, identifying whether traffic management is deployed for (de)prioritizing certain network flows, and measuring whether networks add interconnections and upgrade capacity. Measuring the network impact of COVID-19 will illuminate the Internet’s strengths and weak points and is a crucial step towards improving the Internet’s future resilience in the face of pandemics, natural disasters, large scale conflict, and terrorist attacks. The Internet is designed for resiliency, but large cloud and content providers have been avoiding public Internet exchange points and the public Internet in favor of private interconnection and private wide-area networks. This project will understand the impact of these decisions. The relative performance of these strategies under stress should play a critical role in informing future research, funding, and design of critical Internet infrastructure. All of the data, measurement tools, and analysis code used for this study will be published to the greatest extent permitted by our affiliated organizations and prevailing data privacy regulations, with links to these artifacts posted athttps://covid19-internet-resilience.github.io/. The goal is to keep these artifacts publicly available in perpetuity via free storage and cloud repositories, though the duration is subject to the availability of such resources. The tools and code will be maintained for as long as they remain useful for measuring Internet resilience.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.

COVID-19 的传播给日常生活带来了前所未有的持续变化，包括就地避难令、企业和学校普遍关闭，以及在家工作和在家上学的程度达到了前所未有的水平。该项目将衡量互联网满足这些需求的能力，包括比较其在 COVID-19 高峰之前、期间和之后的性能； COVID-19 和受影响较小的人群；以及是否以及为了提供这种丰富的理解，该项目将结合多个互联网规模的数据集，这些数据集提供互补的视图，以调查对 COVID-19 的响应如何影响互联网以及网络的反应具体而言，该项目将衡量工作负载的情况。通过测量全球流量模式以及拥堵对全球性能的影响，应对 COVID-19 的变化及其对网络的影响。此外，该项目将通过监控指示重新路由的路径变化来测量网络如何应对工作负载的这些变化。因应对措施而引发的交通高峰期间COVID-19，确定是否部署流量管理来优先考虑某些网络流量，并衡量网络是否增加互连和升级容量。衡量 COVID-19 的网络影响将阐明互联网的优势和弱点，是至关重要的一步。提高互联网未来面对流行病、自然灾害、大规模冲突和恐怖袭击的弹性互联网是为弹性而设计的，但大型云和内容提供商一直在避免使用公共互联网交换点和公共互联网。私人的该项目将了解这些决策在压力下的相对表现，在为关键互联网基础设施的未来研究、资助和设计提供信息方面发挥着关键作用。用于本研究的测量工具和分析代码将在我们的附属组织和现行数据隐私法规允许的最大范围内发布，并在 https://covid19-internet-resilience.github.io/ 上发布这些工件的链接。是为了保留这些文物通过免费存储和云存储库永久公开可用，但持续时间取决于此类资源的可用性，只要这些工具和代码对衡量互联网弹性仍然有用，就会一直保留。该奖项反映了 NSF 的法定使命，并具有通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
