摘要： An apparatus is provided for detecting the presence of multimedia content in one or more transactions and for classifying the multimedia content in the one or more transactions. The apparatus can include a traffic processor configured to acquire one or more handshake messages associated with the transactions. The apparatus can also include a multimedia detector configured to determine a domain name requested by a specific terminal based on the one or more handshake messages, and to detect the presence of the multimedia content data in the transactions using the determined domain name. The detection of the presence of the multimedia content can be used for at least one of optimizing or reporting of the multimedia content before the multimedia content is provided to the specific terminal.

摘要： A system and method is provided for determining a client device identity. In one implementation, a method is provided that can include receiving a request from a client device. The method can also include determining, based on the client device request, a subscriber identification. After determining the subscriber identification, the method can include acquiring, from a transactional history database, transactional device data associated with the subscriber identification. In some embodiments, the transactional device data can include one or more counts associated with one or more device types. The method can also include determining, based on the transactional device data, the client device identity. In some embodiments, the determination of the client device identity can include selecting a device type of the one or more device types with the maximum count and setting the client device identity to the selected device type.

摘要： A system and method is provided for controlling multimedia data transmission to a communication device via a network. The system comprises a de-muxer configured to obtain a first multimedia data for transmission and a flow controller configured to evaluate an estimated buffer time associated with the communication device. If the estimated buffer time satisfies a first threshold condition, the flow controller updates a current transmitting state to be a pacing state. And if the estimated buffer time satisfies a second threshold condition, the flow controller updates the current transmitting state to be a bursting state. The system also comprises a muxer configured to transmit the first multimedia data at a transmitting rate corresponding to the bursting state or the pacing state.
