Large file uploading method based on concurrent transmission mode

The invention provides a large file uploading method based on a concurrent transmission mode and belongs to the computer application technology field; the large file uploading method based on the concurrent transmission mode comprises a file parsing module, a concurrent transmission module, an analysis corrector and a file reduction module; the client reads the large file and translates the large file into the byte stream in the file parsing module for forming a plurality of byte streams being the same in size, the concurrent transmission module sends the byte streams to the file receiving end in a concurrent transmission mode, and the file receiving end recombines and reduces the byte streams into the primary file through the file reduction module according to the sequence mark after receiving the file streams.
