Problems solved by technology

[0003] In the prior art solution, when the congestion control algorithm is selected between the network server and the user terminal, the network server randomly selects it. In this way, the congestion control algorithm selected by the network server may not be suitable for the user terminal, resulting in a decrease in TCP transmission efficiency.

Abstract

The embodiment of the invention discloses a data transmission method, comprising the steps of acquiring information for determining a congestion control algorithm; according to the information for determining the congestion control algorithm, determining the congestion control algorithm used when performing data transmission with a user terminal; and using the congestion control algorithm to perform data transmission with the user terminal. The embodiment of the invention also provides a network server, a user terminal and a system. According to the method provided by the invention, the corresponding congestion control algorithm can be selected according to the access type and access network mode of the user terminal, and the TCP transmission efficiency can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data transmission method, a network server, a user terminal and a system. Background technique [0002] Transmission Control Protocol (TCP, Transport Control Protocol) is currently the most widely used transmission protocol on the network, which provides end-to-end reliable data transmission. With the gradual increase of the amount of information transmission and the increasingly complex composition of the network, the possibility of network congestion is increasing. In order to prevent network congestion, a series of TCP congestion control algorithms have been proposed. TCP's congestion control algorithm is generally used to implement congestion avoidance and congestion control. Congestion avoidance is a prevention mechanism, and its purpose is to prevent the network from entering a congested state, so that the network can run in a state of high throu...
