Problems solved by technology

[0003] The delay and packet loss are mainly caused by network congestion. When the port of the network device is congested, the packets enter the queue and wait for scheduling, which increases the delay; when the number of packets is greater than the line speed and buffer capacity of the port, packet loss occurs

Abstract

The invention discloses a video data processing method and device and a computer readable storage medium, and relates to the technical field of network transmission. The video data processing method comprises: identifying a message of a preset service flow in acquired video flow, determining a message discarding probability corresponding to the preset service flow, and performing packet loss processing on the message of the corresponding preset service flow based on the message discarding probability corresponding to the preset service flow. According to the embodiment of the invention, the message of each preset service flow can be identified, and corresponding packet loss processing is carried out according to the message discarding probability corresponding to each service flow. Therefore, congestion control for the specific service flow is realized, and the service quality is not influenced. Moreover, the calculated amount is small, and the congestion control efficiency is high.

Description

technical field [0001] The present invention relates to the technical field of network transmission, in particular to a video data processing method, device and computer-readable storage medium. Background technique [0002] 4K / 8K, AR / VR UHD video services have very strict requirements on the bearer network. Taking 4K video as an example, the requirements for smooth 4K video playback are: the network end-to-end delay should be less than 10ms, and the average packet loss rate should be less than 0.5%. [0003] The delay and packet loss are mainly caused by network congestion. When the port of the network device is congested, the packets enter the queue and wait for scheduling, which increases the delay; when the number of packets is greater than the line speed and buffer capacity of the port, packet loss occurs . [0004] In order to avoid network congestion, random early detection (Random Early Detection, abbreviated: RED) algorithm, weighted random prediction rate (Weight...
