Abstract: A photographing method is provided. In the method, based on a video call between terminals at two places, each terminal previews, in a preset template, real-time preview video streams of the two parties. The two parties may separately adjust a picture of a local preview stream, and obtain a respective high-definition image through snapping when a preview group photo image is satisfying. Through file backhaul, one terminal can generate a high-resolution remote group photo based on snapped high-definition images of the terminals, a picture adjustment parameter during snapping, and the preset template.

Abstract: In a video quality assessment method, an assessment model is first generated based on a subjective assessment result of a user on each sample in a sample set and based on a parameter set (a parameter type in the parameter set may include at least one of a packet loss rate, a delay, and a jitter) of each sample. Therefore, when video quality is being assessed, a parameter set of a to-be-assessed video is obtained first, where the parameter set of the to-be-assessed video has a same parameter type as the parameter set of each sample that is used to generate the assessment model; and then video quality of the to-be-assessed video is assessed based on the assessment model and the parameter set of the to-be-assessed video, to obtain an assessment result.

Abstract: This application provide a data flow processing method and a device. A host determines a priority corresponding to a first data flow to be sent to a switch, and adds the priority to the first data flow to generate a second data flow that includes the priority. The host sends the second data flow to the switch, so that the switch processes the second data flow according to the priority of the second data flow. A host assigns a priority to a data flow, and the switch does not need to determine whether the data flow is an elephant flow or a mouse flow, thereby saving hardware resources of the switch. The switch does not need to determine the priority of the data flow, thereby processing the data flow in a timely manner.

Abstract: A method, apparatus, and system for implementing node port virtualization on a fiber channel in the field of communication technologies are provided. Multiple different virtual Node Port (N_port) identifications (IDs) are allocated to each of multiple N_ports, of an N_port virtualization (NPV) switch, corresponding to an N_port ID of a remote node. Because a virtual N_port ID is allocated, to each remote node, for more than one N_port of the NPV switch, regardless of which N_port of these N_ports a node connected to the NPV switch is registered for, the node can obtain the virtual N_port ID that is of each remote node and that is corresponding to the N_port. Therefore, any node connected to the NPV switch can communicate with any remote node, thereby improving communication efficiency.
