摘要:

针对视频初始缓冲队列长度难以准确测量的问题,对非加密的优酷和加密的YouTube两类视频平台进行研究,提出了视频初始缓冲队列长度测量方法。通过识别分析视频流量特征,关联流量行为与播放状态,构建视频指纹库,实现了队列长度的准确测量。实验结果表明,两类视频平台的测量结果均能够精确到帧,完全满足准确评估视频体验质量的需要。

关键词: 视频QoE参数, 初始缓冲队列, 加密流量分析

Abstract:

To resolve the difficulty in accurately measure the length of video initial buffering queue,two video platforms,non-encrypted Youku and encrypted YouTube,were selected to research,and the video initial buffer queue length measurement method was proposed.By identifying and analyzing the characteristics of video traffic,correlating the traffic behavior with the playing state,constructing video fingerprint database,accurate measurement of queue length was realized.The experimental results show that the measurement results of the two types could be accurate to the frame,fully meeting the need to accurately evaluate the quality of the video experience.

Key words: video QoE parameter, initial buffer queue, encrypted traffic analysis
