    Abstract: Examples described herein relate to a packet processing device that includes circuitry to: request network resource consumption data from one or more other packet processing devices by indication in a header of a reliable transport protocol and transmit the request in a packet that includes the indication in the header. In some examples, the header includes an option field of a transmission control protocol (TCP) packet. In some examples, the network resource consumption data includes a largest network resource consumption data in a path from a sender to a receiver, and potentially one or more next largest network resource consumption data.

    IPC: H04L12/801

    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 network interface device that includes circuitry to: adjust a rate of packet transmissions by Explicit Congestion Notification (ECN)-based congestion control based on phase of operation and congestion metrics comprising queue depth at one or more intermediate switches. In some examples, the circuitry is to adjust the rate of packet transmissions by multiplicative decrease or increase based on a number of inflight bytes. In some examples, the circuitry is to adjust the rate of packet transmissions by additive decrease or increase based on congestion metric from the one or more intermediate switches at one or more intermediate switches.

    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 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.
