Congestion control method and device for data transmission, computer equipment and storage medium

Abstract

The invention relates to a congestion control method and a device for data transmission, computer equipment and a storage medium. The method comprises the following steps: collecting detection information, inputting the detection information into a bandwidth measurement and calculation network for measurement and calculation to obtain a target network bandwidth corresponding to each connection channel, and performing congestion control on to-be-transmitted data on each connection channel according to the target network bandwidth corresponding to each connection channel. According to the method, network detection is carried out by using the bandwidth measurement network, and congestion control is carried out based on the detection result, so that the effect of separation of detection and control is realized, and the problems of high complexity and poor control effect of the congestion control algorithm caused by simultaneous network detection and control in the traditional congestion control algorithm are solved. Moreover, in the method, network bandwidth measurement and calculation are carried out by utilizing the bandwidth measurement and calculation network based on the detection information of multiple dimensions, so that the effect of accurately and quickly measuring and calculating the current bandwidth of the network is achieved, and the efficiency and the stability of service data transmission are improved.

technical field [0001] The present application relates to the technical field of communication of medical equipment, in particular to a congestion control method, device, computer equipment and storage medium for data transmission. Background technique [0002] As the latest wireless network technology, 5G cellular network is widely used in business communications in various industries, especially in medical scenarios, due to its high operating frequency band, large coverage area, ability to carry a large number of services, and the characteristics of millimeter wave frequency bands. The file content of business transmission includes but is not limited to DICOM, JPEG, audio and video, etc. [0003] However, in the actual transmission process, due to the poor penetration of the 5G cellular network, the air signal is more sensitive to obstacles, so the network bandwidth, delay and other performance indicators often fluctuate, and network packet loss may occur.

Problems solved by technology

[0003] However, in the actual transmission process, due to the poor penetration of the 5G cellular network, the air signal is more sensitive to obstacles, so the network bandwidth, delay and other performance indicators often fluctuate, and network packet loss may occur

All kinds of business data are sent through the 5G cellular network, and the transport layer adopts the TCP protocol. When the 5G cellular network is unstable, there may be a temporary decrease in bandwidth, an increase in delay, or network packet loss, which will trigger congestion in the TCP protocol. The start of the control mechanism leads to a sharp drop in network throughput and may lead to a sharp increase in delay, which eventually leads to a decline in business data transmission efficiency and a sharp increase in transmission time
