Abstract

The invention discloses a data transmission method and device. Wherein, the method includes: receiving the target message sent by the data sending end through the first target transmission path, wherein the first target transmission path is one of the multiple transmission paths established between the data receiving end and the data sending end at the first moment The optimal transmission path, the target message is used to indicate that there is missing data in the original data sent by the data sender; determine whether the target message is a preset message, where the preset message is the original data sent by the data sender after Forward error correction coded message; if it is judged that the target message is a preset message, the target message is analyzed to obtain the analysis information, and the analysis information is sent to the data sending end, wherein the analysis information is used for Notify the data sender to retransmit the data indicated by the analysis information. The invention solves the technical problem of low data transmission efficiency in the prior art.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data transmission method and device. Background technique [0002] In the existing Internet, multi-homed hosts with multiple parallel access links are more and more common, and there are multiple reachable paths between multi-homed hosts. This feature provides a new way to improve the performance of existing transmission protocols. train of thought. However, two widely used transmission protocols Transmission Control Protocol (Transmission Control Protocol, referred to as TCP) and User Datagram Protocol (User Datagram Protocol, referred to as UDP) in mainstream operating systems (for example, Linux systems) can only be used. A reachable path between the data sender and the data receiver to transmit data cannot make full use of the multi-path feature of the multi-homed host to improve the transmission performance. Therefore, some multi-path transmission schemes appear, s...
