Abstract: Examples described herein relate to a network interface device comprising dataplane circuitry, when operational, is to generate a representation of aggregated network resource consumption information based on network resource consumption at the network interface device or at least one other network device and to transmit at least one packet with a multi-bit representation of the aggregated network resource consumption information to a second network interface device. In some examples, the network resource consumption information comprises one or more of: available transmit bandwidth, transmit bandwidth used by a queue or flow, queue depth, measured queueing time duration, expected queueing time duration, packet latency, or normalized in-flight bytes.

Abstract: Examples described herein relate to a network element comprising an ingress pipeline and at least one queue from which to egress packets. The network element can receive a packet and generate a congestion notification packet at the ingress pipeline to a sender of the packet based on detection of congestion in a target queue that is to store the packet and before the packet is stored in a congested target queue. The network element can generate a congestion notification packet based on a queue depth of the target queue and likelihood the target queue is congested. The likelihood the queue is congested can be based on a probabilistic function including one or more of Proportional-Integral (PI) or Random Early Detection (RED). The network element can determine a pause time for the sender to pause sending particular packets based at least on a time for the target queue to drain to a target level.

Abstract: Examples described herein relate to an apparatus that includes a network interface device comprising circuitry to identify at least one congested queue, predict occupancy level of the at least one congested queue when at least one sender is predicted to receive at least one congestion notification and transmit the at least one congestion notification to the at least one sender through zero or more intermediate nodes. In some examples, to identify at least one congested queue, the circuitry is to identify the at least one congested queue based on at least one fill level. In some examples, to identify at least one congested queue, the circuitry is to identify the at least one congested queue based on at least one predicted fill level at a predicted time the at least one sender receives the at least one congestion notification.
