Abstract: A technique for processing a lock request is provided. A first lock server is a takeover lock server of a second lock server. The first lock server enters a silent state after learning that a fault occurs in the second lock server, where a silent range is a resource for which the second lock server has assigned permission. The first lock server receives an acquire lock request that is originally sent to the second lock server, and the first lock server assigns lock permission for a corresponding resource according to the acquire lock request if the second lock server has not assigned resource for the resource. By means of this solution, an impact range of a fault occurring in a lock server can be reduced, and stability of a lock management system is improved.

Abstract: A terminal device sends first information to a cloud device, where the first information indicates a posture and a location of the terminal device at a first moment. Then, the terminal device receives information about a first field of view image from the cloud device, where the first field of view image is a field of view image corresponding to the posture and the location of the terminal device at the first moment. The terminal device displays an image within a field of view range of the terminal device at a second moment based on the information about the first field of view image and a posture change and a location change of the terminal device from the first moment to the second moment.

Abstract: Embodiments of this application disclose a method, an apparatus, and a system for implementing data transmission. The method includes: obtaining, by a sending device, a data packet in a target data flow; and sending the data packet through each of at least two physical links between the sending device and a receiving device, where the data packet sent through each of the at least two physical links includes a same sequence number. Because the data packet in the target data flow is sent through different physical links, not through only one physical link, when a transmission latency of the data packet is increased due to a bandwidth instability factor such as burst traffic or electromagnetic wave interference on any physical link, the receiving device can combine, into a target video flow, data packets that are sent through other physical links and that have a lower latency.
