The transmission speed can be determined by the priority level of the transmission of a plurality of files. For example, the operation of simultaneously transmitting 2 files, referred to as a and B, sets the priority of the file a to be higher than that of the file B, and the transmission speed of the file a is faster than that of the file B.
103. And receiving a confirmation message from the second terminal, and issuing the transmission files to the corresponding partition node servers according to the partition node identifiers corresponding to the transmission files.
