Abstract: The invention relates to a method for transporting data between application programs assigned to different interconnected computers of a computer network, the method being based on a connectionless and packet-oriented transport method capable of transporting the data packets between application programs. When a data packet is transmitted from the application program of a source computer to that of the destination computer, a retransmission timer (RT) and an acknowledgement timer (QT) are initiated. After the data packet has been initially received, it is transferred to the application program of the destination computer. Each time the destination computer receives a data packet, an acknowledgement packet is transmitted back to the source computer, confirming receipt of the data packet.
