Title:
ホスト・コンピュータ・システムとイーサネット(R)・アダプタの間におけるデータ転送
Document Type and Number:
Japanese Patent JP2004531001
Kind Code:
A
Abstract:
A method and system for transmitting and receiving data from a host computer system to an Ethernet adapter are provided. The method comprises establishing a connection between the host system and the Ethernet adapter pushing a transmit or receive request message from a host system device driver to the Ethernet adapter's request queue. Access to host memory is transferred to the Ethernet adapter. If data is being transmitted to the Ethernet adapter, the adapter reads the data from a location in host memory specified in the transmit request message, and then transmits the data onto transmission media (e.g. wire, fiber). If the request message is a receive request, the adapter reads the data from the media and then sends the data into host memory at the location specified in the receive request message. When the data transfer is complete, the adapter sends a response message back to the host. The response message includes a transaction ID which is used by the host device driver to associate the response message to the original request message.
