Abstract: Embodiments of the present disclosure provide a method for determining a transmission link. In one example method, a second device receives a first path discovery message sent by a first device. The first path discovery message is path discovery information or a forwarded message of the path discovery message. The path discovery message is used to determine a data transmission link between a path initiation device and a path response device. The first path discovery message carries first time-frequency resource information of the first device, and the first time-frequency resource information indicates a time-frequency resource that can be used by the first device to transmit data. The second device determines a sending manner of a second path discovery message according to the first time-frequency resource information. The second path discovery message is a forwarded message of the first path discovery message.

Abstract: Embodiments of the present invention provide a method for paging between NAN devices, and a NAN device, and relate to the field of communications technologies, so that paging can be directly performed between NAN devices when there is no central node. The method includes: sending, by a first NAN device, a first paging message in a first window; receiving a paging response message sent by a second NAN device that meets first service information; and determining, according to the paging response message, whether to perform data transmission with the second NAN device. The first paging message carries the first service information, and the first service information is used to describe a service that needs to be performed by the NAN device. The method is applied to a NAN mechanism.

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. Therefore, the first device can fully consider, by using the traffic flow identification model, attribute information of a device associated with the traffic flow, to improve an identification rate of the type of the traffic flow, and ensure an identification effect of the type of the traffic flow.

Abstract: A device provides a soft access point in, for example, a wireless network. The device sends, to an access point, a resource request message that includes cluster information about a cluster of network units connected to the device. The access point allocates first resources for communications within the cluster according to the cluster information, and sends to the device a resource allocation message specifying the first resources. The device uses the first resources for communications within the cluster.
