Abstract: This application discloses a Wi-Fi Aware link establishment method and system, an electronic device, and a storage medium. The Wi-Fi Aware link establishment method includes: A primary device receives first connection information sent by a secondary device, where the first connection information includes a Wi-Fi Aware service name needed by the secondary device. The primary device sends second connection information to the secondary device based on the Wi-Fi Aware service name needed by the secondary device, where the second connection information includes confirmation information, the confirmation information is notification information indicating that the primary device confirms that there is the Wi-Fi Aware service name needed by the secondary device. The primary device obtains a Wi-Fi Aware data path request frame sent by the secondary device. The primary device completes link establishment with the secondary device based on the Wi-Fi Aware data path request frame.

Abstract: A hot live video determining method is provided. A network device first obtains a plurality of video request messages for a target video; then determines statistical information of the target video based on the plurality of video request messages, where the statistical information includes a quantity of video request messages for the target video that are obtained in specified duration and fragment information of a video fragment requested in each video request message; and finally determines, based on the statistical information, whether the target video is a hot live video. According to the method, the network device can identify the hot live video in the Internet, so the network device can carry the hot live video in a multicast manner, to avoid breakdown that is of a network and a video server and that is caused by transmitting the hot live video in a unicast method.

Abstract: The present invention provides a live video transmission method and system and an apparatus. According to the method, an M2U device receives a UDP request sent by a client, where the UDP request includes a live channel identifier and is used to request video data of a live channel corresponding to the live channel identifier, and the live channel identifier includes a multicast address or a URL. Then, the M2U device obtains the video data corresponding to the live channel identifier, and obtains a source IP address and a source port of the UDP request, where the source IP address and the source port of the UDP request are used as a destination IP address and a destination port of a UDP unicast packet to be subsequently sent to the client.
