DATA TRANSFER METHOD AND DATA TRANSFER PROGRAM

A processor transfers a file in a memory by TCP (Transmission Control Protocol). The processor (100) divides single file (4) in the memory (110) into the data group of the N unit (N is an integer more than 2) (4-0-4-N-1), and creates the transfer jobs of N unit including data group of the N unit and offset position (OF). The processor (100) assigns the transfer job to the transfer thread of the M unit which is the maximum number of simultaneous connection in the TCP and transfers the data group and the offset position of the M unit appointed by the transfer job of the M unit among the data group and the offset positions of the N unit appointed by the transfer job of the N unit by the connection of the M unit in parallel.
