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: Technologies for payload direct memory storing (PDMS) for out-of-order delivery of packets in remote direct memory access (RDMA) are described. A responder device includes an RDMA transport layer that can receive packets out of order and allow direct data placement of packet data in order. The responder device receives a first packet with a first packet number and first location information. The responder device stores first packet data to a first location according to the first location information. The responder device also receives a second packet and stores second packet data to a second location according to the second location information. A second packet number indicates that the first packet is received out of order. The first and second packet data are stored in order. The responder device can provide an indication that a message has arrived in response to determining that all packets of the message have arrived.

Abstract: Technologies for spreading a single transport flow across multiple network paths in remote direct memory access (RDMA) over converged Ethernet (RoCE) and InfiniBand are described. A network interface controller receives a first packet and a second packet of a transport flow directed to a second node. The network interface controller assigns a first network routing identifier to the first packet and a second network routing identifier to the second packet, the first network routing identifier corresponding to a first network path between the first and second nodes, the second network routing identifier corresponding to a second network path between the first node and the second node. The network interface controller schedules a first packet of the transport flow to be sent via the first network path and a second packet of the transport flow to be sent via the second network path.
