Network traffic classification is important to network operators to ensure visibility of traffic. Network management, monitoring, and other services are built upon such classification results for improving quality of service. Compared with traffic classification in non-mobile setting, classification in mobile settings focuses on applications and has become increasingly important. Traditionally, a rule-based method is deployed in a deep packet inspector (DPI) engine for traffic classification. However, with the explosive growth in application usage, the complicated relationships including the use of content delivery networks (CDN) and sharing behaviors among applications make such methods less effective. The traffic may be identified wrongly when one application is connected to another application's server.
