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.
