| 摘要 |
An apparatus receives packets from a network and inserts the packet data into the memory of a computer system. The invention reduces the amount of computer system memory bandwidth required to receive packets through the use of a retained data buffer. Packet headers and a summary of packet validation results are processed by network stacks within the computer system to identify the intended memory buffer in which the packet payload is to be placed. Packet payload data is directly placed from the retained data buffer to the intended memory buffer without the use of intermediate buffers. A preferred embodiment includes a data retention network interface card (DRNIC) which includes the required data retention buffer for use in direct placement of received data.
