论文摘要
19009年的大流行大大改变了在很短的时间内数十亿人的生活方式。在本文中，我们评估了由于在线进行的人类活动增加而导致的互联网潜伏期的影响。该研究的重点是意大利，该研究经历了地方当局施加的重大限制，但还包括有关西班牙，法国，德国，瑞典和整个欧洲的结果。对一系列测量值的分析表明，对网络的影响可能很大，尤其是在延迟变异性的增加方面。在意大利，我们观察到，在锁定期间，平均额外延迟的标准偏差（相对于该地区路径的最小延迟的额外时间）约为大流行前值的3-4倍。同样，在意大利，数据包损失是大流行之前的约2-3倍。对其他国家和整个欧洲的影响也不可以忽略不计，而具有不同的水平和不同的模式。
The COVID-19 pandemic dramatically changed the way of living of billions of people in a very short time frame. In this paper, we evaluate the impact on the Internet latency caused by the increased amount of human activities that are carried out on-line. The study focuses on Italy, which experienced significant restrictions imposed by local authorities, but results about Spain, France, Germany, Sweden, and the whole of Europe are also included. The analysis of a large set of measurements shows that the impact on the network can be significant, especially in terms of increased variability of latency. In Italy we observed that the standard deviation of the average additional delay -- the additional time with respect to the minimum delay of the paths in the region -- during lockdown is ~3-4 times as much as the value before the pandemic. Similarly, in Italy, packet loss is ~2-3 times as much as before the pandemic. The impact is not negligible also for the other countries and for the whole of Europe, but with different levels and distinct patterns.
