当今的流量项目几乎是互联网上的几乎58％的视频流量。必须完成流量的特征，但可以根据我们在此工作中显示的大量测量来得出来自交通行为的重要质量指标。在欧洲两个城市的56个网络场景中，YouTube应用程序的录像数量超过18个不同的视频。视频摊位旨在使网络运营商获得视频流流量的特征，以量化当今最重要的应用程序之一的最重要的QoE退化因素。
Today’s traffic projections speak of almost 58% video traffic across the Internet. Nearly all video traffic is encrypted, accounting for more than 50% encrypted traffic worldwide. To analyze video traffic today, or even estimate its quality in the network, a deep look into the traffic characteristics has to be done. But then, important quality metrics from the traffic behavior can be derived. Based on extensive measurements we show in this work how to measure and estimate video stalls for mobile adaptive streaming. The underlying dataset includes more than 900 hours of video footage from the native YouTube app, measured over 18 different videos in 56 network scenarios in two cities in Europe. We outline a possible approach to estimate the video playback buffer size based on uplink video chunk requests in real-time to break down the video stalls. This work is intended as a tool for network operators to receive further knowledge of the characteristics of video streaming traffic to quantify the most important QoE degradation factors of one of the most important applications today.
