Abstract

The present invention provides a file transmission method, comprising: acquiring a data stream corresponding to an original file; extracting feature information in the data stream, and acquiring the file format type of the original file according to the feature information; The type selects the corresponding file compression algorithm, compresses the original file with the selected file compression algorithm to generate a compressed file; obtains the compression algorithm type information corresponding to the file compression algorithm, and sends the compression algorithm type information and the compressed file. In addition, a file transmission device is also provided. The above-mentioned file transmission method and device can reduce the amount of data to be transmitted and save transmission time.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a file transmission method and device. Background technique [0002] When a network device in the traditional technology transmits a file, in order to improve the transmission speed, the gzip compression method is usually used to compress the file, and the transmission speed is improved by reducing the amount of transmitted data. However, the gzip compression method has a high compression rate for text type files, but a very low data compression rate for multimedia type (video, audio) files, so that the effect of improving the transmission speed of multimedia type files is not obvious. Contents of the invention [0003] Based on this, it is necessary to provide a file transfer method that can save time-consuming transfer. [0004] A file transfer method comprising: [0005] Obtain the data stream corresponding to the original file; [0006] extracting feature information in...
