Research on active monitoring based QQLive real-time information acquisition system

Based on the analysis of QQLive protocol, an active monitoring based QQLive real-time information acquisition system was presented by the in-depth study of characteristic message and characteristic payload in the communication process of QQLive. The system acquires the channel list and program information, at the same time monitors the viewing user information by forging the client to send message to the server. Theoretical analysis and experiments demonstrate that the active monitoring based method has higher controllability and accuracy in comparison with the passive monitoring based method. The active monitoring based real-time information acquisition system provides an important data foundation to the content detection and user behavior analysis of P2P streaming media.
