教育服务提供商(ESP)在教育数字化中发挥着至关重要的作用，因为他们为学生和教师配备了可靠的设备，并在学校提供高质量的互联网接入。本文调查了ESP使用部署在全国教育设备网络中的大规模被动设备内体验质量(QOE)监控系统进行的四个月的连续测量。这些测量覆盖了800多个教育中心和大约4000台在学校和家庭中使用的设备。使用这个丰富的数据集，我们提出了一个详尽的浏览行为的描述，并量化了在这种教育背景下的网络和视频QOE。网络QOE结果显示，与家庭连接相比，学校Wi-Fi网络的性能更好，这表明由于新冠肺炎大流行导致家庭教育的相关性越来越高，ESP可能会出现几个问题。
Education Service Providers (ESPs) play a crucial role in the digitization of education as they equip students and teachers with reliable devices and provide high quality Internet access at schools. This paper investigates four months worth of continuous measurements conducted by an ESP using a large-scale, passive, in-device Quality of Experience (QoE) monitoring system deployed into a nationwide network of education-purpose devices. These measurements cover more than 800 education centers and about 4000 devices, used both in schools and at home. Using this rich dataset, we present an exhaustive characterization of the browsing behavior, and a quantification of the web and video QoE in this educational context. Web QoE results showed a better performance for school Wi-Fi networks compared to home connections, suggesting that several issues may arise for ESPs due to the increasing relevance of home-schooling caused by the COVID-19 pandemic.
