    Abstract: A method for communication includes provisioning each node in a network with a respective set of two or more network addresses. Each node in succession is assigned a respective network address from the respective provisioned set that has not been assigned for use by any preceding node. Upon finding for a given node that all the network addresses in the respective provisioned set were assigned to preceding nodes, the preceding nodes are searched to identify a candidate node having an additional network address in the respective provisioned set, other than the assigned respective network address, that was not yet assigned to any of the nodes. The additional network address is assigned to the candidate node instead of the respective network address that was previously assigned to the candidate node, and the assigning of the network addresses to the nodes in the succession resumes following the candidate node.

    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: A network node includes a network adapter and a host. The network adapter is coupled to a communication network. The host includes a processor running a client process and a communication stack, and is configured to receive packets from the communication network, and classify the received packets into respective flows that are associated with respective chunks in a receive buffer, to distribute payloads of the received packets among the chunks so that payloads of packets classified to a given flow are stored in a given chunk assigned to the given flow, and to notify the communication stack of the payloads in the given chunk, for transferring the payloads in the given chunk to the client process.

    Abstract: A system including a network interface layer, and a physical network connection configured to connect with a networking medium. The network interface layer is configured to: A) receive a plurality of user datagram protocol (UDP) message segments from the physical network connection; B) coalesce the plurality of UDP message segments into a coalesced UDP message; and C) send the coalesced UDP message to an application layer external to the system. Related apparatus and methods are also provided.

    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.
