Internet video traffic classification using QoS features

This paper addresses the issue of effective classification of video traffic with the view of QoS guarantee, and presents a modified K-Singular Value Decomposition (K-SVD) classification framework based on the concept of QFAg (QoS based Flow Aggregation). By statistical analysis of video flows on large-scale real networks, we define 5 Quality of Service (QoS) categories with the features of downstream/upstream rates. To investigate the sparsity...
