Abstract: Embodiments of this application provide a fever alarm method based on body temperature monitoring and a related device, applied to a wearable device. The method may include: collecting a body temperature of a user in a first time period, where the first time period is time for which the wearable device is attached to skin of the user; determining a temperature monitoring mode that the user is in; and generating a fever alarm when detecting that the body temperature of the user in the first time period meets a fever condition corresponding to the body temperature monitoring mode, where different body temperature monitoring modes correspond to different fever conditions.

Abstract: This application discloses a method, apparatus and storage medium for application identification. A network device performs flow behavior feature analysis according to a flow table to obtain a plurality of services. Each service includes one IP address and one port identifier, and one application may usually include a group of services. Therefore, the network device clusters the plurality of services according to the flow table and a domain name table, to obtain a plurality of application types. Each application type includes a plurality of services. Each application type corresponds to one application. Further, the network device may determine a label corresponding to each of the plurality of application types, the label identifying an application to which a data flow belongs.
