Abstract: A network node includes one or more network adapters and a bonding driver. The one or more network adapters are configured to communicate respective data flows over a communication network by applying a transport layer protocol that saves communication state information in a state of a respective network adapter. The bonding driver is configured to exchange traffic including the data flows of an application program that is executed in the network node, to communicate the data flows of the traffic via one or more physical links of the one or more network adapters, and, in response to a physical-transport failure, to switch a given data flow to a different physical link or a different network path, transparently to the application program.

Abstract: A method for network access of remote memory directly from a local instruction stream using conventional loads and stores. In cases where network IO access (a network phase) cannot overlap a compute phase, a direct network access from the instruction stream greatly decreases latency in CPU processing. The network is treated as yet another memory that can be directly read from, or written to, by the CPU. Network access can be done directly from the instruction stream using regular loads and stores. Example scenarios where synchronous network access can be beneficial are SHMEM (symmetric hierarchical memory access) usages (where the program directly reads/writes remote memory), and scenarios where part of system memory (for example DDR) can reside over a network and made accessible by demand to different CPUs.

Abstract: Systems and methods enable session sharing for session-based remote direct memory access (RDMA). Multiple queue pairs (QPs) can be added to a single session and/or session group where each of the QPs has a common remote. Systems and methods may query a session ID for an existing session group and then use the session ID with an add QP request to join additional QPs to an existing session. Newly added QPs may share one or more features with existing QPs of the session group, such as encryption parameters. Additionally, newly added QPs may be configured with different performance or quality of service requirements, thereby isolating performance, and permitting true scaling for high performance computing applications.

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: A combined request may be used to reduce a number of communications between a client and server to establish a remote connection. The combined request can include one or more add session requests along with one or more add queue pair (QP) requests. The server, receiving the combined request, may then evaluate each request in turn to determine whether a session can be established and then to add a QP to that session and provide, in a combined reply, connection information back to the client. The client may then verify the connection information and begin transmitting data. As a result, a total number of communications between the client and server can be reduced.

Abstract: A network adapter includes a network interface, a bus interface, a hardware-implemented data-path and a programmable Data-Plane Accelerator (DPA). The network interface is to communicate with a network. The bus interface is to communicate with an external device over a peripheral bus. The hardware-implemented data-path includes a plurality of packet-processing engines to process data units exchanged between the network and the external device. The DPA is to expose on the peripheral bus a User-Defined Peripheral-bus Device (UDPD), to run user-programmable logic that implements the UDPD, and to process transactions issued from the external device to the UDPD by reusing one or more of the packet-processing engines of the data-path.
