| 摘 要： | 为了改善网络视频流的细粒度分类效果，该文分析视频流传输过程中的特征变化与流分类之间的关系。根据不同类型的视频流具有不同的下行传输速率变化模式，提出一种新的基于下行速率传输的视频流分类特征--M值概率分布，并使用支持向量机(SVM)实现网络视频流的分类。实验结果表明，M值概率分布相比较于已有的常见流特征，可以更好地实现6种典型的网络视频流分类。

| Abstract: | To obtain better results for fine-grained video traffic classification, this paper analyzes the relationship between the feature variations during transmission and video traffic classification. According to the nature that different types of video services contain different downlink transmission rate variation patterns, a new video flow feature M value probability distribution, based on downlink byte rate variation is proposed, and video classification is realized by Support Vector Machine (SVM). The experimental results show that the probability distribution of M value is a better feature for classification of six kinds of common network video applications than other commonly used flow features. |
