摘要： Network interface circuitry for a secure one-way data transfer from a sender's computer (“Send Node”) to a receiver's computer (“Receive Node”) over a data link, such as an optical fiber or shielded twisted pair copper wire communication cable, comprising send-only network interface circuitry for transmitting data from the Send Node to the data link, and receive-only network interface circuitry for receiving the data from the data link and transmitting the received data to the Receive Node, wherein the send-only network interface circuitry is configured not to receive any data from the data link, and the receive-only network interface circuitry is configured not to send any data to the data link. The network interface circuitry may use various interface means such as PCI interface, USB connection, FireWire connection, or serial port connection for coupling to the Send Node and the Receive Node.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, an improved mechanism for handling receipt of data packets in a system utilizing an offload network adapter. The offload network adapter may include logic that permits the offload network adapter to delay notification of data reception to the host system in different ways. The advantage of delaying the notice of data packet reception to the host system is the potential for aggregation of several data packets, which can arrive immediately after the first one, for example, in a single notification. Given a stream with continuous data packet arrival, a value may be set, either statically or dynamically, for notification delay and this value may be configurable for the host system per communication socket.

摘要： A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information maintenance, the number of communications needed between the host system and the offload network adapter may be reduced. In addition, offloading of these functions to the offload network adapter permits bulk notification of established connections and state information to the host system rather than piecemeal notifications as is present in known computing systems.
