Abstract: A control method and apparatus for video stream transmission, a device, and a medium that can be applied to various scenarios is provided. The control method for video stream transmission may include: obtaining attribute data and network environment data that are in a process in which a video streaming server downloads a video stream; predicting, based on the attribute data and the network environment data, a network status in which the video streaming server downloads the video stream within a preset time period, to obtain a prediction result; and transmitting the prediction result to a streaming strategy adjuster. The prediction result is configured for instructing the streaming strategy adjuster to determine a streaming strategy corresponding to the video streaming server.

Abstract: In embodiments of the present disclosure, a method is provided for performing a frame processing operation on a broadcast/multicast frame at a physical access point (AP). A pre-processing operation is performed on the frame at a protocol layer between a physical layer and an upper layer of the AP to obtain a pre-processed frame. The pre-processing operation comprises a common operation to be performed for the plurality of virtual interfaces at the protocol layer. In this way, by performing a pre-processing operation common to the virtual interfaces supported by the physical AP, the consumption of resources caused by the performance of repeated operations in the frame processing operation can be reduced.
