论文摘要
Covid-19-大流行导致数十亿人的日常习惯发生了巨大变化。用户越来越多地依靠家庭宽带互联网访问来进行工作，教育和其他活动。这些更改导致对Internet流量模式的相应更改。本文旨在表征这些变化对美国互联网服务提供商的影响。我们研究了三个问题：（1）由于19号大流行，美国的交通需求如何变化？ （2）这些变化对互联网性能产生了什么影响？ （3）服务提供商如何应对这些变化？我们使用来自各种来源集合的数据研究这些问题。我们对美国两个大ISP的互连数据的分析显示，2020年第一季度的峰值交通率增加了30-60％。特别是，我们观察到下游峰值的交通量增加了13-20％，而上游峰值增加了30％以上。此外，我们观察到ISP的性能以及交通量变化的显着差异，并在发出全家订单后明显的潜伏期增加，然后在四月后稳定流量。最后，我们观察到，在使用使用变化时，ISP在互连方面具有积极的增强能力，比正常容量增强的速度是两倍以上。同样，视频会议应用程序增加了其网络足迹，使其广告的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.
