Abstract: Embodiments of this application disclose a data transmission method, an apparatus, and a device in a Wi-Fi network, to improve reliability of providing differentiated data transmission services by a network access device. The method includes: receiving an uplink packet; recording a real-time transmission indication and uplink 5-tuple information that are carried in the uplink packet; then receiving a downlink packet, where the downlink packet carries downlink 5-tuple information; and then, if a service type of the downlink packet is a preset service type, and the downlink 5-tuple information matches the uplink 5-tuple information, preferably forwarding the downlink packet based on the real-time transmission indication.

Abstract: This application provides a traffic flow identification method and apparatus, and a model generation method and apparatus. The traffic flow identification method includes: A first device obtains a to-be-identified traffic flow, collects statistics about packet header information in the to-be-identified traffic flow in a preset time window, to obtain to-be-identified packet header statistics information, and obtains to-be-identified terminal-side information based on the to-be-identified traffic flow. Further, the first device determines a type of the to-be-identified traffic flow based on the to-be-identified terminal-side information and the to-be-identified packet header statistics information by using a traffic flow identification model.
