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.
