Abstract: Technologies for optimizing the spreading of traffic across multiple local output ports while considering both local load and end-to-end (E2E) load are described. One device has multiple outgoing ports and a network adapter that determines, for a first flow of packets, a first end-to-end (E2E) congestion rate of at least some of the outgoing ports. The network adapter determines a port state of at least some of the outgoing ports. The network adapter receives a first packet associated with the first flow of packets. The network adapter determines, using a first desired rate for the first flow, the first E2E congestion rates, and the port states, i) a first time at which the first packet is to be transmitted and ii) a first outgoing port on which the first packet is to be transmitted. The first packet is sent on the first outgoing port at the first time.

Abstract: A network adapter includes a port and one or more circuits. The port communicates packets over a network in which switches forward packets in accordance with tuples of the packets. The one or more circuits are to hold a user-programmable scheme specifying assignments of the packets of a given flow destined to a peer node to sub-flows having respective different tuples, assign first packets of the given flow to one or more of the sub-flows in accordance with the user-programmable scheme, by setting respective tuples of the first packets, transmit the first packets to the peer node via the port, monitor notifications received from the network, the notifications being indicative of respective states of the sub-flows, based on the notifications and on the user-programmable scheme determine an assignment of second packets of the given flow to the sub-flows, and transmit the second packets to the peer node via the port.
