Abstract: A system and a method for evaluating transmission performance related to a network node, and a related device are disclosed. The system includes a network node and a control node. The network node is configured to obtain a test packet, and process the test packet by using a virtual switch, to generate a mirrored packet corresponding to the test packet. The mirrored packet carries a generation timestamp and generation location information. The control node is configured to receive the mirrored packet from the network node, to evaluate, based on the mirrored packet, transmission performance of at least a part of link that is related to the network node and that is in a path. The control node obtain transmission performance of the network node in the path and the transmission performance of at least a part of link that is related to the network node.

Abstract: A picture selection method and an electronic device are provided. The method includes: displaying a first interface in an interaction scenario of a first application, where the first interface includes a picture selection button; and displaying a target album interface in response to a first operation performed by a user to trigger the picture selection button, where the target album interface includes thumbnails of at least two pictures that carry different identifier information or at least two picture sets that carry different identifier information; and where identifier information is generated based on interaction scenarios of at least two applications, and the identifier information includes at least one of an application name of an application, time of an interaction scenario of an application, or a quantity of times in an interaction scenario of an application.
