COVID-19 大流行导致数十亿人的日常习惯发生巨大变化。用户越来越多地依赖家庭宽带互联网接入来进行工作、教育和其他活动。这些变化导致了互联网流量模式的相应变化。本文旨在描述这些变化对美国互联网服务提供商的影响。我们研究三个问题：(1) 由于 COVID-19 大流行，美国的交通需求发生了怎样的变化？ (2) 这些变化对互联网性能有何影响？； (3) 服务提供商如何应对这些变化？我们使用来自不同来源的数据来研究这些问题。我们对美国两家大型 ISP 互连数据的分析显示，2020 年第一季度峰值流量增加了 30-60%。特别是，我们观察到主要 ISP 的下游峰值流量增加了 13-20%，而上游峰值增加了 30% 以上。此外，我们观察到随着流量变化，各 ISP 的性能存在显着差异，发布居家令后延迟明显增加，4 月后流量趋于稳定。最后，我们观察到，为了应对使用情况的变化，ISP 积极增加互连容量，其速度是正常容量增加的两倍以上。同样，视频会议应用程序也增加了其网络覆盖范围，使其宣传的 IP 地址空间增加了一倍以上。
The COVID-19 pandemic has resulted in dramatic changes to the daily habits of billions of people. Users increasingly have to rely on home broadband Internet access for work, education, and other activities. These changes have resulted in corresponding changes to Internet traffic patterns. This paper aims to characterize the effects of these changes with respect to Internet service providers in the United States. We study three questions: (1) How did traffic demands change in the United States as a result of the COVID-19 pandemic?; (2) What effects have these changes had on Internet performance?; (3) How did service providers respond to these changes? We study these questions using data from a diverse collection of sources. Our analysis of interconnection data for two large ISPs in the United States shows a 30–60% increase in peak traffic rates in the first quarter of 2020. In particular, we observe traffic downstream peak volumes for a major ISP increase of 13–20% while upstream peaks increased by more than 30%. Further, we observe significant variation in performance across ISPs in conjunction with the traffic volume shifts, with evident latency increases after stay-at-home orders were issued, followed by a stabilization of traffic after April. Finally, we observe that in response to changes in usage, ISPs have aggressively augmented capacity at interconnects, at more than twice the rate of normal capacity augmentation. Similarly, video conferencing applications have increased their network footprint, more than doubling their advertised IP address space.
