Abstract: A cross-network bridging apparatus includes a bus interface and bridging circuitry. The bus interface is configured for connecting to a system bus. The bridging circuitry is configured to translate between (i) system-bus transactions that are exchanged between one or more local devices that are coupled to the system bus and served by the system bus and one or more remote processors located across a network from the apparatus, and (ii) data units that convey the system-bus transactions, for transmitting and receiving as network packets over the network to and from the remote processors.

Abstract: Computing apparatus includes a host computer, including at least first and second host bus interfaces. A network interface controller (NIC) includes a network port, for connection to a packet communication network, and first and second NIC bus interfaces, which communicate via first and second peripheral component buses with the first and second host bus interfaces, respectively. Packet processing logic, in response to packets received through the network port, writes data to the host memory concurrently via both the first and second NIC bus interfaces in a sequence of direct memory access (DMA) transactions, and after writing the data in any given DMA transaction, writes a completion report to the host memory with respect to the given DMA transaction while verifying that the completion report will be available to the CPU only after all the data in the given DMA transaction have been written to the host memory.

Abstract: A network adapter includes a network interface controller and a processor. The network interface controller is to communicate over a peripheral bus with a host, and over a network with a remote storage device. The processor is to expose on the peripheral bus a peripheral-bus device that communicates with the host using a bus storage protocol, to receive first I/O transactions of the bus storage protocol from the host, via the exposed peripheral-bus device, and to complete the first I/O transactions in the remote storage device by (i) translating between the first I/O transactions and second I/O transactions of a network storage protocol, and (ii) executing the second I/O transactions in the remote storage device. For receiving and completing the first I/O transactions, the processor is to cause the network interface controller to transfer data directly between the remote storage device and a memory of the host using zero-copy.

Abstract: Apparatus including a first interface to a host processor, a second interface to transmit and receive data packets having headers and payloads, to and from a packet communication network, a memory holding context information regarding a flow of the data and assigning serial numbers to the data packets in the flow, according to a session-layer protocol, and processing circuitry between the first and second interfaces and having acceleration logic, to decode the data records according to the session-layer protocol, using and updating the context information based on the serial numbers and the data records of the received packets, and processing circuitry writing the decoded data records through the first interface to a host memory. The acceleration logic, upon receiving in a given flow a data packet containing a serial number that is out of order, reconstructs the context information and applies that context information in decoding data records in subsequent data packets in the flow.

Abstract: Packet processing apparatus includes a first interface coupled to a host processor and a second interface configured to transmit and receive data packets to and from a packet communication network. A memory holds context information with respect to one or more flows of the data packets conveyed between the host processor and the network in accordance with a reliable transport protocol and with respect to encoding, in accordance with a session-layer protocol, of data records that are conveyed in the payloads of the data packets in the one or more flows. Processing circuitry, coupled between the first and second interfaces, transmits and receives the data packets and includes acceleration logic, which encodes and decodes the data records in accordance with the session-layer protocol using the context information while updating the context information in accordance with the serial numbers and the data records of the transmitted data packets.

Abstract: A system includes a host processor, which has a host memory and is coupled to store data in a non-volatile memory in accordance with a storage protocol. A network interface controller (NIC) receives data packets conveyed over a packet communication network from peer computers containing, in payloads of the data packets, data records that encode data in accordance with the storage protocol for storage in the non-volatile memory. The NIC processes the data records in the data packets that are received in order in each flow from a peer computer and extracts and writes the data to the host memory, and when a data packet arrives out of order, writes the data packet to the host memory without extracting the data and processes the data packets in the flow so as to recover context information for use in processing the data records in subsequent data packets in the flow.

Abstract: A method, apparatus, and computer program product for processing a data record including encrypted and decrypted data is described. Various embodiments include receiving a data record including ciphertext and plaintext blocks and determining whether each block in the data record is a ciphertext block or a plaintext block. If a block is a ciphertext block, the ciphertext block is stored into a ciphertext record, decrypted into a plaintext block utilizing a decryption algorithm, and stored in a plaintext record. If the block is a plaintext block, the plaintext block is stored into the plaintext record, encrypted into a ciphertext block utilizing an encryption algorithm, and stored in the ciphertext record. Embodiments described also include authenticating the data record by passing each block of the ciphertext record to an authentication scheme and outputting the plaintext record to a destination application.
