视频流媒体是互联网的重要组成部分，广泛应用于IPTV、视频会议和E-learning。用户关于视频内容的体验质量（QoE）对于服务提供商改善服务并向终端用户提供服务质量是重要的。视频质量受到网络中的分组重排序、延迟和丢失的影响，这降低了终端用户的QoE。在本文中，我们进行了几个实验，视频流创建人工包重新排序，以衡量用户分层水平的视频质量以及最终用户可接受的网络水平。我们使用NetEm工具在视频流中创建人工数据包重排序，录制和播放视频供参与者感知，并研究不同数据包重排序百分比的QoE。从我们的实验中，我们发现，当视频质量由于网络流量而重新排序时，用户的QoE会降低。这项工作将帮助内容提供商根据服务水平协议向用户提供QoE。[图形]。
Video streaming is an important part of the Internet and it is widely used for IPTV, video conferencing and E-learning. The quality of experience (QoE) of users about the video contents is important for service providers to improve services and provide quality of service to end users. The video quality is affected by packet reordering, delay and loss in the network, which degrades the QoE of end users. In this paper, we conducted several experiments on video streaming creating artificial packet reorder to measure user stratification level of video quality as well as acceptable network level for end users. We used NetEm tool for creating artificial packet reorder in video streaming, recording and playing videos for participants for perception, and investigated the QoE of different packet reorder percentage. From our experiments, we found that QoE of users is decreased when video quality is reordered due to network traffic. This work will help content providers to provide QoE to users based on service level agreements.[GRAPHICS].
