Abstract

The invention provides a document transmission method which comprises the steps of obtaining a data flow corresponding to an original document, extracting feature information in the data flow, obtaining a document format type of the original document according to the feature information, selecting a corresponding document compression algorithm according to the document format type, compressing the original document through the selected document compression algorithm to generate a compressed document, obtaining compression algorithm type information corresponding to the document compression algorithm, and sending the compression algorithm type information and the compressed document. In addition, the invention further provides a document transmission device. According to the document transmission method and device, the transmitted data size can be reduced, and transmission consumption time is reduced.

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...
