Abstract
An object of the present invention is to increase speed of retransmission. A communication device has a transmission unit, a reception unit, a comparison unit, and a retransmission control unit. The transmission unit transmits first data toward a communication party. The reception unit receives second data as the first data received and returned by the communication party. The comparison unit is a process unit in a data link layer and compares the transmitted first data with the received second data. The retransmission control unit is a process unit in the data link layer and, when the transmission first data and the received second data do not match as a result of the comparison by the comparison unit, controls retransmission of the first data.
