Abstract: A method includes receiving, by a second electronic device, a first working key sent by a first electronic device, and a first working key set sent by a first server to the second electronic device after the first server determines that a user of the first electronic device is a target user. In response to the second electronic device determining that the first working key set comprises the first working key, determining, by the second electronic device, that a user of the second electronic device is a suspected target user.

Abstract: A method for sending a data packet includes, sending, by a transmit node, a data packet based on a target sending rate and occupation of a data sending queue, where a sending rate for sending the data packet is proportional to the target sending rate, and the occupation of the data sending queue limits a quantity of data packets. The transmit node receives a feedback message from a receive node indicating the capability of the receive node for processing the data packet. The transmit node may adjust the sending rate based on the feedback message.

Abstract: A link detection technology. In a link detection method, when a target event occurs on paths, in a plurality of paths, whose quantity exceeds a preset quantity, whether the paths on which the target event occurs share a bottleneck link is detected, and congestion control is performed. It can be learned that in the technical solution provided in the embodiments of this application, the target event is a trigger, and shared bottleneck detection is performed after the quantity of the paths on which the target event occurs exceeds the preset quantity. This implements purposeful link detection, reduces system overheads, and brings a fast convergence speed.
