Abstract: A network element one or more network ports, network time circuitry and packet processing circuitry. The network ports are configured to communicate with a communication network. The network time circuitry is configured to track a network time defined in the communication network. In some embodiments the packet processing circuitry is configured to receive a definition of one or more timeslots that are synchronized to the network time, and to send outbound packets to the communication network depending on the timeslots. In some embodiments the packet processing circuitry is configured to process inbound. packets, which are received from the communication network, depending on the timeslots.

Abstract: A method using a memory and queue handling logic, including accessing a work control structure (WCS) configured “first-in-first-out” holding work control records (WCRs) each including a field defining work to be carried out and a completion indicator indicating whether the work has completed, and initially set to indicate that the work has not completed: upon fetching a work request (WR) for execution, pushing a WCR corresponding to the WR to the WCS, and: A) inspecting the WCR at a head of the WCS, B) when the completion indicator of the WCR at the head of the WCS indicates that the unit of work associated with the WCR at the head of the WCS has been completed, popping the WCR at the head of the WCS from the WCS, and reporting completion of the WCR at the head of the WCS to a host processor, and C) iteratively performing A, B, and C.

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: An apparatus includes a memory and control circuitry. The control circuitry is configured to receive packets, which are en-route to undergo transport-layer processing in a network device in accordance with a transport protocol that requires arrival of the packets in a sequential order, to detect that one or more of the packets deviate from the sequential order, to buffer the one or more deviating packets in the memory, and, using the memory, to reorder the packets and provide the packets in the sequential order to the network device.

Abstract: A work descriptor identifying a plurality of workflow tasks to be performed by a hardware device is generated by a host system. The work descriptor corresponds to a performance completion message generated by the hardware device in response to completing performance of the work descriptor. One or more completion indicators are added to the work descriptor. Each of the completion indicators instructs the hardware device to generate one or more additional completion messages during performance of the work descriptor in response to a trigger criterion. The work descriptor is caused to be available to the hardware device for execution.

Abstract: A system including a network interface layer, and a physical network connection configured to connect with a networking medium. The network interface layer is configured to: A) receive a plurality of user datagram protocol (UDP) message segments from the physical network connection; B) coalesce the plurality of UDP message segments into a coalesced UDP message; and C) send the coalesced UDP message to an application layer external to the system. Related apparatus and methods are also provided.

Abstract: Technologies for spreading a burst of data across multiple network paths in remote direct memory access (RDMA) over converged Ethernet (RoCE) and InfiniBand are described. A network interface controller sends a first burst of a transport flow directed to a second node over a first network path. The network interface controller determines that a second burst is to be sent over a different network path, and identifies a second network path using a multipath context. The multipath context stores a first weight value or a first state associated with the first network path and a second weight value or a second state associated with the second network path. The network interface controller sends the second burst of data to the second node via the second network path.

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.
