Abstract: A method includes detecting, by an accelerator of a networking device, a serial number of a first data packet is out of order with respect to a previous data packet within a first flow of data packets associated with a packet communication network, wherein the serial number is assigned to the first data packet according to a transport protocol. The method includes reconstructing context data associated with the first flow of data packets, wherein the context data comprises encoding information for encoding of data records containing data conveyed in payloads of data packets in the first flow of data packets according to a storage protocol. The method includes using, by the accelerator, the reconstructed context data in processing a data record associated with a second data packet within the first flow, wherein the second data packet is subsequent to the first data packet in the first flow of 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: 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 receive (Rx) pipeline, a transmit (Tx) pipeline and congestion management circuitry. The Rx pipeline is configured to receive packets sent over a network by a peer network adapter, and to process the received packets. The Tx pipeline is configured to transmit packets to the peer network adapter over the network. The congestion management circuitry is configured to receive, from the Tx pipeline and from the Rx pipeline, Congestion-Control (CC) events derived from at least some of the packets exchanged with the peer network adapter, to exchange user-programmable congestion control packets with the peer network adapter, and to mitigate a congestion affecting one or more of the packets responsively to the CC events and the user-programmable congestion control packets.

Abstract: A method including configuring a transmit process to store information including a queue of packets to be transmitted, the queue defining transmit process packets to be transmitted, each packet associated with a transmission time, and configuring a synchronization process to receive from the transmit process at least some of the information. The synchronization process performs one of: A) accessing a dummy send queue and a completion queue, and transmitting one or more of the transmit process packets in accordance with a completion queue entry in the completion queue, and B) sends a doorbell to transmission hardware at a time when at least one of the transmit process packets is to be transmitted, the synchronization process including a master queue configured to store transmission entries, each transmission entry including a transmit process indicator and an indication of transmit process packets to be transmitted. Related apparatus and methods are also described.
