<p>PROBLEM TO BE SOLVED: To transmit packets with a high throughput and high reliability. SOLUTION: A communication unit 1A forms a packet TA1 whose packet length is longest, transmits it to a communication unit 1B. When no acknowledgment ACK is returned from the communication unit 1B, the communication unit 1A forms a packet TA2 whose packet length is decreases and transmits it to the communication unit 1B. When no ACK with respect to the packet TA2 is returned, the communication unit 1A forms a packet TA3 whose length is furthermore decreased and transmits it to the communication unit 1B. Upon the receipt of a packet TB3 that is an ACK packet from the communication unit 1B, the communication unit 1A forms a packet DA1 with the same packet length as that of the packet TA3 where user data to be sent first are arranged and transmits it to the communication unit 1B. Then the communication unit 1A sequentially arranges the user data to the packet whose length is the same as that of the packet TA3 and transmits the packet to the communication unit 1B.</p> |
