Problems solved by technology

[0003] Most of the existing congestion control algorithms use a set of relatively fixed rules to apply to all users, and refer to fewer network characteristics, but the network conditions of different users are often different, so relatively fixed congestion control algorithms are difficult to ensure that all users have a better good experience

Abstract

The invention provides an AI-based congestion control algorithm, device and equipment and a medium, and the method comprises the steps that a network state feature extractor extracts a network state according to a state feature space of a feature processor, and obtains a feature attribute value of the network state through calculation; an audio and video state feature extractor extracts feature attribute values of the audio and video states and calculates a reward value through a reward calculator; an AI code rate estimator calculates a code rate estimated value through the reward value and the characteristic attribute value of the network state; and a receiving end or a sending end performs adjustment according to the code rate estimation value, so the network characteristic data of multiple dimensions can be effectively utilized, the current bandwidth value can be predicted more accurately, and a timely and effective congestion control effect is realized.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an AI-based congestion control algorithm, device, device and medium. Background technique [0002] Congestion control is a research hotspot in the field of video conferencing. Network congestion will lead to increased delay and packet loss rate, resulting in increased audio and video delay and even freezes, affecting user experience. Congestion control is an important means of video conference quality assurance, which can reduce network delay and relieve network congestion. There are many current congestion control schemes, such as GCC congestion control algorithm, Sendside-BWE algorithm, etc. [0003] Most of the existing congestion control algorithms use a set of relatively fixed rules to apply to all users, and refer to fewer network characteristics, but the network conditions of different users are often different, so relatively fixed congestion control algorithms ...
