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.

Abstract: A method for assessing quality of a VR video, including: obtaining a bit rate, a frame rate, resolution, and TI of a VR video, and determining a mean opinion score (MOS) of the VR video based on the bit rate, the frame rate, the resolution, and the TI of the VR video. The MOS of the VR video is used to represent quality of the VR video. Further, an assessment apparatus is provided. In the embodiments, accuracy of an assessment result of a VR video can be improved.
