<p>PROBLEM TO BE SOLVED: To send data efficiently by controlling the system such that a receiver side sends a reply to the transmitter side upon the receipt of a packet to eliminate a useless time when the transmitter side cannot send data at all. SOLUTION: The transmitter side has information 7 of a remaining reception buffer capacity (window side) of a receiver side. In the case of sending a packet, the window size information 7 is used to continue transmission 4 by a capacity receptible by the receiver side. In order to avoid a deficient window size, the receiver side returns an acknowledge including idle window size information to the transmitter side. Thus, the transmitter side updates its own window size 7 by the received window size information through control means 22, 23, 24.</p> |
