PROBLEM TO BE SOLVED: To receive divided data from a device on a transmission side and reconstruct the original data from the divided data at high speed.SOLUTION: A receiving device 1 receives data by using an automatic repeat request based on a window limiting the number of receivable packets, stores the received data in a block area of a storage area 6 corresponding to a sequence number, and sets an identifier for a first data area 5 to a state that data has been stored. When an identifier for a first data area 5 corresponding to a reception wait indicating sequence number indicates that data is stored in a block area corresponding to the reception wait indicating sequence number, a control unit 3 transfers, to a second store unit 7, data in a block area corresponding to sequence numbers in the range indicated by this identifier in which data is contiguously stored. The control unit 3 updates the reception wait indicating sequence number and the index number of a second data area 4 to numbers corresponding to the next reception wait indicating sequence numbers, respectively. |
