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 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.

Abstract: A network device includes a first interface, a second interface and circuitry. The first interface is configured to communicate at least with a first memory. The second interface is configured to communicate over a network with a peer network device coupled to a second memory. The circuitry is configured to (i) receive a request to transfer data over the network between the first memory and the second memory in accordance with a pattern of offsets to be accessed in the first memory or in the second memory, and (ii) transfer the data in accordance with the request.

Abstract: Methods, systems, and devices for message signaled interrupt (MSI-X) tunneling on a host device exposed by a bridge connection are described. A device may receive data and a first interrupt signal from a remote destination over a network protocol. The device may receive the data and/or the first interrupt signal over the bridge connection, via a tunneled communication from the remote destination. The device may generate a second interrupt signal based on the first interrupt signal and a local interrupt configuration provided by a system bus driver of the device. The device may inject the data and the second interrupt signal over the system bus. Injecting the data and injecting the second interrupt signal may include ensuring the data is made available to the system bus driver, prior to the interrupt handler receiving the second interrupt signal.

Abstract: Devices, methods, and systems are provided. In one example, a device is described to include a device interface that receives data from at least one data source; a data shuffle unit that collects the data received from the at least one data source, receives a descriptor that describes a data shuffle operation to perform on the data received from the at least one data source, performs the data shuffle operation on the collected data to produce shuffled data, and provides the shuffled data to at least one data target.

Abstract: In one embodiment, a communication apparatus, including a network interface configured to receive over a network a sequence of data packets of a network flow having a defined packet order, wherein the network interface is configured to receive an out-of-order data packet instead of multiple missing data packets according to the defined packet order, a timer, and packet processing circuitry configured to activate the timer responsively to receiving the out-of-order data packet, and set the time period over which the tinier is activated responsively to a quantity of the multiple missing data packets.
