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.
