摘要： Embodiments of this application disclose a congestion control method and a related device. A Transmission Control Protocol offload engine TOE sends a congestion control notification to a central processing unit CPU, where the congestion control notification instructs the CPU to obtain a target parameter, and the target parameter is used by the CPU to generate a congestion control calculation result. The TOE obtains the congestion control calculation result returned by the CPU, where the congestion control calculation result includes a congestion control window value. The TOE sends a packet based on the congestion control window value. In this application, the TOE and the CPU implement congestion control together. When a new congestion control algorithm emerges, the new congestion control algorithm may be applied without changing a structure of the TOE. Therefore, in this application, an upgrade period of the congestion control algorithm can be shortened, and flexibility can be improved.

摘要： A method for performing a video conference in a mobile phone is provided. The video conference involves a plurality of conferencing devices that display presentation content and a video image of one or more participants in the video conference. The mobile phone receives a first and second real-time transport protocol (RTP) packets including a video image of a participant and presentation content in the video conference, respectively. The video image of the participant includes a face portion of the participant and a background portion. The mobile phone decodes the video image of the participant and the presentation content, extracts the face portion of the participant from the video image of the participant, overlays the face portion of the participant over a portion of the presentation content to form a composite image, and displays the composite image on a display device of the mobile phone.
