Abstract

PURPOSE:To resend a transmission frame to be resent by informing the sequence number of a transmission frame to be resent to the transmission side instantly in detecting the non-sequence of the sequency number in the reception of a transmission frame. CONSTITUTION:A transmission frame from an opposite information processing unit is received by a reception control section 2. When an error detection control section 4 informs a number larger than the expected sequence number for the reception at present to a retransmission sequence number control section 5. The control section 5 forms a reply frame to send it to a transmission control section 1. The transmission control section 1 sends a reply frame to the opposite information control. A reception control section 2 of the opposite information processing unit receives the reply frame and informs it to a frame retransmission control section 6. The control section 6 decides the frame to be sent again and sends the result to the transmission control section 1. Thus, the transmission frame to be sent is sent again.
