    Abstract: A method for communication includes receiving at a receiving node over a network from a sending node a succession of data packets belonging to a sequence of transactions, including at least one or more first packets belonging to a first transaction and one or more second packets belonging to a second transaction executed by the sending node after the first transaction, wherein at least one of the second packets is received at the receiving node before at least one of the first packets. At the receiving node, upon receipt of the data packets, data are written from the data packets in the succession to respective locations in a buffer. Execution of the second transaction at the receiving node is delayed until all of the first packets have been received and the first transaction has been executed at the receiving node.

    Abstract: A method for communication, includes routing unicast data packets among nodes in a network using respective Layer-3 addresses that are uniquely assigned to each of the nodes. Respective Layer-2 unicast addresses are assigned to the nodes in accordance with an algorithmic mapping of the respective Layer-3 addresses. The unicast data packets are forwarded within subnets of the network using the assigned Layer-2 addresses.

    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.

    IPC: H04L67/1097

    Abstract: A method for communication includes receiving in a network device work requests posted by a host processor to perform a series of communication transactions, including at least a first transaction and a second transaction comprising first and second operations to be executed in a sequential order in response to corresponding first and work requests posted by the host processor. In response to the work requests, data packets are transmitted over a network from the network device to a destination node and corresponding responses are received from the destination node. Based on the received responses, completion of the first operations in the first transaction is reported from the network device to the host processor according to the sequential order, and completion of the second operation in the second transaction is reported from the network device to the host processor regardless of whether the first transaction has been completed.

    Abstract: Communication apparatus includes a host interface, configured to be coupled to a host processor having a host memory, and a network interface, which is configured to receive over a network from a sending node data packets conveying operations for execution in a sequential order on a predefined queue pair (QP), including at least a first packet conveying a posted write operation and a second packet conveying a non-posted write operation. Packet processing circuitry is configured to execute the posted write operation in accordance with the sequential order so as to write first data to the host memory prior to the execution of any subsequent operations in the sequential order, and to execute the non-posted write operation so as to write second data to the host memory while allowing one or more of the subsequent operations in the sequential order to be executed prior to completion of writing the second data.
