Network interface that places bulk data directly into application buffers

摘要

A direct data placement implementation for a data reassembly process. Data within a segmented protocol data unit is placed directly in preassigned application buffers. The network interface card has buffer space into which message headers, segment headers and indicators of escaped data (ie the directly placed data) and size of escaped data are placed. A single buffer can contain this information for a complete PDU (or message) and is handed over to enable the next process to run on a per message basis. The system may operate with TCP and iSCSI protocols.
