Zusammenfassung:The present invention provides a method, computer program product, and distributed data processing system to allow the hardware mechanism of the Internet Protocol Suite Offload Engine (IPSOE) to interpret the iSCSI commands, process the iSCSI commands, and to interpret the iSCSI command completion results with the iSCSI driver. The distributed data processing system comprises endnodes, switches, routers, and links interconnecting the components. The endnodes use send and receive queue pairs to transmit and receive messages. The endnodes segment the message into frames and transmit the frames over the links. The switches and routers interconnect the endnodes and route the frames to the appropriate endnodes. The endnodes reassemble the frames into a message at the destination.
