Abstract

The invention discloses a network congestion control method and device, a terminal and a storage medium, and the method comprises the steps: determining a packet sending rate according to the current network condition information and a trained neural network model, and sending a packet to a receiving end according to the packet sending rate; receiving a return message sent by the receiving end, and updating the network bandwidth occupancy rate according to the return message; and in a first stage, if the network bandwidth occupancy rate is smaller than a preset bandwidth occupancy threshold value, switching from the first stage to a second stage, and in the second stage, if the network bandwidth occupancy rate is larger than the preset bandwidth occupancy threshold value, switching from the second stage to the first stage, wherein the packet sending rate in the first stage is smaller than the packet sending rate in the second stage. The network congestion control method provided by the invention can realize stable congestion control in a complex network environment.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a network congestion control method, device, terminal and storage medium. Background technique [0002] At present, most of the global Internet data traffic is transmitted through the TCP (Transmission Control Protocol) protocol. As one of the core components of the TCP protocol, the congestion control algorithm seriously affects the performance of network transmission. The congestion control algorithm of the TCP protocol maintains a congestion window. Control the packet sending rate. When the communication link is good, the value of the congestion window can be increased appropriately to improve link utilization. When the link is congested, the congestion window should be reduced in time to prevent the link from being overloaded and causing the network to crash . [0003] In the early stage of the Internet, the communication medium was mainly wired network, its bandwidth w...
