Method for transmitting data via a network

摘要

A communication controller (205) at the sending computer (201) divides data transferred from a host (101) into sub-ACK unit packets, and transfers them sequentially to a destination without waiting for the sub-ACK's being subsequently provided by the destination. A communication controller (206) at the receiving computer (202) issues a sub-ACK to the sending computer (201) for each of the sub-ACK unit packet, if the sub-ACK packet has been normally received and otherwise issues retransmission request for the sub-ACK unit packets and merges data included in the sub-ACK unit packets into the initial data, after they are normally received.
