    Abstract: A network adapter includes circuitry and one or more ports. The ports connect to a communication network including multiple network elements. The circuitry accesses outbound messages that are pending to be sent over the communication network to multiple remote nodes via the ports. At least some of the outbound messages request the remote nodes to send respective amounts of data back to the network adapter. Based on the amounts of data requested by the outbound messages, the circuitry forecasts a bandwidth of inbound response traffic, which is expected to traverse a selected network element in response to the outbound messages toward the network adapter, determines a schedule for transmitting the outbound messages to the remote nodes so that the forecasted bandwidth meets a bandwidth supported by the selected network element, and transmits the outbound messages to the remote nodes in accordance with the determined schedule.

    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 timer is activated responsively to a quantity of the multiple missing data packets.

    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.

    Abstract: An apparatus for cache management includes an interface and a processor. The interface is for communicating with a cache memory configured to store data items. The cache controller is configured to obtain a classification of the data items into a plurality of groups, to obtain respective target capacities for at least some of the groups, each target capacity defining a respective required size of a portion of the cache memory that is permitted to be occupied by the data items belonging to the group, and to cache new data items in the cache memory, or evict cached data items from the cache memory, in accordance with a policy that complies with the target capacities specified for the groups.
