Abstract: A transmitter can manage when a transmit queue is permitted to transmit and an amount of data permitted to be transmitted. After a transmit queue is permitted to transmit, the transmit queue can be placed in a sleep state if the transmit queue has exceeded its permitted data transmission quota. The wake time of the transmit queue can be scheduled based on a token accumulation rate for the transmit queue. The token accumulation rate can be increased if the transmit queue has other data to transmit after the data transmission. The token accumulation rate can be decreased if the transmit does not have other data to transmit.

Abstract: Examples described herein include configuration of a transmitting network device to identify a source queue-pair identifier in at least some of the packets that are transmitted to an endpoint destination. A network device that receives packets and experiences congestion can determine if a congestion causing packet includes a source queue-pair identifier. If the congestion causing packet includes a source queue-pair identifier, the network device can form and transmit a congestion notification message with a copy of the source queue-pair identifier to the transmitting network device. The transmitting network device can access a context for the congestion causing packet using the source queue-pair identifier without having to perform a lookup to identify the context.

Abstract: At a network-connected device, congestion at an egress queue can be detected. A potential source of congestion can be identified based on characteristics of a packet that caused the egress queue to become congested. The source of congestion can be a congestion group of transmitters. A group congestion message can be sent to the group of transmitters. The message can identify the packet that caused the egress queue to become congested. Transmitters can respond to the message by reducing their peak transmission rate.
