Abstract
A first loss determination sectionof a first communication devicedetermines that a data unit is lost if an acknowledgment response for the transmitted data unit from a second communication deviceis not received within a predetermined time and retransmits the data unit when the determination is made. When a determination sectiondetermines that a spurious timeout has occurred, a window control sectionsets a target value for decreasing the size of a congestion window and then gradually decreases the size of the congestion window to the target value when the acknowledgment response is received. Therefore, in a case of executing a response algorithm for changing a slow start threshold and the congestion window, if a segment loss occurs subsequent to the spurious timeout, an efficient loss recovery is achieved and the throughput is improved.
