Abstract

Embodiments of the present invention provide a data transmission method and device. The data transmission method of the present invention includes: the first device judges according to the data flow information whether the data transmission protocol TCP parameters in the data flow corresponding to the data flow information need to be modified; the data flow information Including at least one of the following information: information of the first device, information of the second device, business information, network status information; if so, modify the TCP parameters to obtain the modified TCP parameters; the first device generates Modification result of TCP parameters. The invention realizes modifying the TCP parameters corresponding to the data streams according to the data streams of different services of different users.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a data transmission method and device. Background technique [0002] TCP (Transmission Control Protocol, Transmission Control Protocol) is a connection-oriented, reliable, byte stream-based transport layer communication protocol, which provides users with a variety of modification parameters so that users can modify corresponding parameters for different network conditions , to improve data transmission efficiency. [0003] The way to modify the TCP parameters in the prior art is: modify the TCP parameters stored in the system file, save the system file after modification, and execute the corresponding command to make the modification take effect. [0004] However, when performing the above process, the inventor found the following problems in the prior art: since one user can correspond to multiple services, each service corresponds to one TCP s...
