    Abstract: A method for computing includes submitting a first command from a central processing unit (CPU) to a first peripheral device in a computer to write data in a first bus transaction over a peripheral component bus in the computer to a second peripheral device in the computer. A second command is submitted from the CPU to one of the first and second peripheral devices to execute a second bus transaction, subsequent to the first bus transaction, that will flush the data from the peripheral component bus to the second peripheral device. The first and second bus transactions are executed in response to the first and second commands. Following completion of the second bus transaction, the second peripheral device processes the written data in.

    Abstract: A Network Interface (NI) includes a host interface, which is configured to receive from a host processor of a node one or more work requests that are derived from an operation to be executed by the node. The NI maintains a plurality of work queues for carrying out transport channels to one or more peer nodes over a network. The NI further includes control circuitry, which is configured to accept the work requests via the host interface, and to execute the work requests using the work queues by controlling an advance of at least a given work queue according to an advancing condition, which depends on a completion status of one or more other work queues, so as to carry out the operation.

    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: In a data network congestion control in a virtualized environment is enforced in packet flows to and from virtual machines in a host. A hypervisor and network interface hardware in the host are trusted components. Enforcement comprises estimating congestion states in the data network attributable to respective packet flows, recognizing a new packet that belongs to one of the data packet flows, and using one or more of the trusted components and to make a determination based on the congestion states that the new packet belongs to a congestion-producing packet flow. A congestion-control policy is applied by one or more of the trusted components to the new packet responsively to the determination.

    Abstract: A method in a system that includes first and second devices that communicate with one another over a fabric that operates in accordance with a fabric address space, and in which the second device accesses a local memory via a local connection and not over the fabric, includes sending from the first device to a translation agent (TA) a translation request that specifies an untranslated address in an address space according to which the first device operates, for directly accessing the local memory of the second device. A translation response that specifies a respective translated address in the fabric address space, which the first device is to use instead of the untranslated address is received by the first device. The local memory of the second device is directly accessed by the first device over the fabric by converting the untranslated address to the translated address.
