Network transmission congestion control method and device

Abstract

The invention discloses a network transmission congestion control method and device. The method comprises the steps of obtaining a network state parameter, wherein the network state parameter represents network delay; determining a network bandwidth detection mode based on the network state parameter; selecting a congestion control algorithm in the network bandwidth detection mode; and sending a data packet to an opposite side according to a parameter of a congestion window. According to the method and the device, the technical problem that the transmission speed of a wireless network is slowis solved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for controlling network transmission congestion. Background technique [0002] With the popularization and application of mobile Internet, more and more users access Internet website resources through mobile devices to obtain network information and entertainment. However, due to factors such as the complex environment between the mobile device and the network server, repeated changes in the wireless communication environment, limited access flow bandwidth, and uncertain network environment, the user sometimes slows down during the website access process, which can easily cause User complaints and user churn for web application servers. In addition, due to the instability of the wireless network, the relatively high rate of packet loss and retransmission at the transport layer when users access network server resources, factors such as link bandw...

Problems solved by technology

[0002] With the popularization and application of mobile Internet, more and more users access Internet website resources through mobile devices to obtain network information and entertainment. However, due to factors such as the complex environment between the mobile device and the network server, repeated changes in the wireless communication environment, limited access flow bandwidth, and uncertain network environment, users sometimes experience slow speed during website access, which can easily cause User Complaints and Churn for Web Application Servers

In addition, due to the instability of the wireless network, the relatively high rate of packet loss and retransmission at the transport layer when users access network server resources, factors such as link bandwidth asymmetry also cause the problem of slow speed, and the existing congestion control algorithm Whether it is based on packet loss or delay to determine whether the network is congested and the information is single will affect the problem to varying degrees

[0003] Specifically, the disadvantages of the network server for users to access corporate websites in the transport layer solution are as follows: existing application servers are hosted in the IDC computer room, and most of them adopt the default configuration of the operating system. The default configuration of the application server cannot be optimized for the congestion control of the wireless environment; The actual test results of the algorithm performance of the application server with the default configuration in the wireless environment transmission control are not good

[0004] For the above-mentioned problem of slow wireless network transmission speed, no effective solution has been proposed yet
