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，为学生和教师提供可靠的设备，并在学校提供高质量的互联网接入。本文提出了一种大规模、被动、设备内体验质量（QoE）监测系统，该系统已部署到全国教育设备网络中。ESP进行了四个月的连续测量，覆盖了800多个教育中心和大约4000个设备，这些设备在学校和家庭中都有使用。在分析学校网络中web会话的QoE时，我们发现了web浏览和视频QoE模型兼容性的基本问题，这阻碍了对多种服务的qos感知网络管理的成功应用。
Education Service Providers (ESPs) have a paramount role in the digitization of education, providing reliable devices for students and teachers and high quality Internet access at schools. In this paper, a large-scale, passive, in-device Quality of Experience (QoE) monitoring system is presented, which was deployed into a nationwide network of education-purpose devices. Four months' worth of continuous measurements were conducted by an ESP, covering more than 800 education centers and about 4000 devices, used both in schools and at home. When analyzing the QoE of web sessions in school networks, we identify a fundamental issue with the compatibility of web browsing and video QoE models, which inhibits the successful application of QoE-aware network management for multiple services.
