A communication method includes receiving a data packet and obtaining, according to a correspondence between a service package and a packet detection rule (PDR), a target service package corresponding to a target PDR matching the data packet. The method also includes performing data statistics collection based on the target service package, to obtain a data statistics collection result corresponding to the target service package. The method further includes sending the data statistics collection result corresponding to the target service package to a data analysis device. The method additionally includes receiving a data analysis result corresponding to the target service package. The method also includes performing traffic stimulation or traffic suppression on the target service package based on the data analysis result corresponding to the target service package.

Communication method and apparatus

A method for replaying a log on a data node, a data node, and a database system are described. The method is used to improve a log replay speed, and includes: the data node obtaining a plurality of logs, wherein the plurality of logs includes at least one transaction commit log and at least one page operation log; and a first thread of a plurality of threads replaying the at least one page operation log, and a same second thread replaying all page operation logs including an operation on a same page. As such, log replay progress does not need to be synchronized between threads. A process in which the first thread replays the transaction commit log is independent of a process in which at least one second thread replays the at least one page operation log.

Embodiments of this application disclose a method and system for identifying an application identifier (APP ID), and a device. The method includes: receiving, by a packet flow description function network element, a query request that carries a signature parameter of a service data flow; determining an APP ID corresponding to a PFD that matches the signature parameter of the service data flow, as an APP ID corresponding to the service data flow; and sending a query response that carries the APP ID corresponding to the service data flow. The method provided in the embodiments of this application is applicable to APP ID identification.

Method, device and system for identifying application identifier

A system is described for scaling display content on a computing device based on user-to-device distance. A measurement is taken of the distance between the user and the device and a scaling setting is determined using a predefined rule based on the measured distance. The scaling setting is applied to scale content on the display based on the user-to-device distance by changing settings in the operating system or changing scaling in an application. Embodiments include virtual desktop/application and localized implementations.

Scaling display contents based on user-to-screen distance

Embodiments provide a method, a device, and system to implement session management on a UPF network element. The method includes: determining, by a network device, that a first logical interface group on a first UPF network element needs to be migrated; determining, by the network device, a second UPF network element for the first logical interface group; sending, by the network device to the second UPF network element, configuration information of the first logical interface group and information about a first IP address segment corresponding to the first logical interface group, to restore the configuration information of the first logical interface group and the information about the first IP address segment on the second UPF network element; and sending, by the network device, a first message used to restore, on the second UPF network element, information about one or more sessions corresponding to the first logical interface group.
