Abstract
A CPU 41 of a server device 40 measures an elapsed time after transmitting a data segment, and suspends measuring time upon receiving an acknowledgement segment for the data segment. CPU 41 transmits a data segment whose elapsed time has reached a retransmission timeout value. CPU 41 sets, as a retransmission timeout value of a data block, a time value determined according to a monotonically increasing function of a number of transmissions of the data block, during a given time period after the second-time transmission of the data block, while CPU 41 sets a time value which is predetermined and is different from the time value determined by the monotonically increasing function during a period between the first-time transmission and immediately before the second-time transmission of the data block.
