    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.

    IPC: H04L12/803

    Abstract: Examples described herein relate to a network interface device that includes data plane circuitry, when operational, to: identify a flow of packets that is a cause of queue congestion and cause transmission, to an upstream network interface device, of a packet with an identifier of a source queue in the upstream network interface device that requests reduction of transmission of packets from the source queue associated with the upstream network interface device. In some examples, the source queue is identified in a congestion causing packet by the upstream network interface device and wherein the upstream network interface device comprises a prior hop network interface device.

    Abstract: Examples described herein relate to a switch that is to receive a message identifying congestion in a second switch; drop the message; generate a pause frame; and cause transmission of the pause frame to at least one sender of packets to a congested queue in the second switch. In some examples, the message includes one or more of: a destination IP address, Differentiated Services Code Point (DSCP) value, or pause duration for the congested queue. In some examples, the DSCP value is to identify a traffic class of the congested queue. In some examples, the pause frame is consistent with Priority Flow Control (PFC) of IEEE 802.1Qbb (2011). In some examples, the switch is to: store, from the message identifying congestion in the second switch, congestion information associated with the congested queue comprising one or more of: destination internet protocol (IP) address, Differentiated Services Code Point (DSCP) value, or pause end time of the congested queue.

    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.
