Abstract: This application discloses a packet transmission method, an apparatus, a device, and a computer-readable storage medium, and belongs to the field of communication technologies. For example, the method is applied to a first device. The method includes: The first device receives a first packet, where the first packet includes quality guarantee indication information and information about a first application, and the first packet belongs to the first application for which quality guarantee needs to be provided. The first device stores a correspondence between the information about the first application and the quality guarantee indication information based on the received first packet. After receiving a second packet including the information about the first application, the first device provides quality guarantee for the second packet based on the stored correspondence.

Abstract: A video quality assessment method and device are provided. The video quality assessment method includes: obtaining a to-be-assessed video, where the to-be-assessed video includes a forward error correction (FEC) redundancy data packet; when a quantity of lost data packets of a first source block in the to-be-assessed video is less than or equal to a quantity of FEC redundancy data packets of the first source block, generating a first summary packet for a non-lost data packet of the first source block, and generating a second summary packet for a lost data packet of the first source block; and calculating a mean opinion score of video (MOSV) of the to-be-assessed video based on the first summary packet and the second summary packet. The MOSV calculated according to the method is more consistent with real video experience of a user, so accuracy of video quality assessment can be improved.
