Abstract
An in-band telemetry congestion notification system includes a source device that generates and transmits packets. Each of a plurality of switch devices receives each of the packets, provides in-band telemetry information in each of the packets, and transmits each of the packets to a destination device. When the destination device receives a first subset of the packets, it uses the in-band telemetry information included in each of the first subset of the packets to determine a telemetry information baseline. Subsequent to determining the telemetry information baseline, when the destination device receives a second subset of the packet, it uses the in-band telemetry information included in each of the second subset of the packets to determine a departure from the telemetry information baseline that indicates congestion and, in response, generates a congestion notification and transmits the congestion notification via the plurality of switch devices to the source device.
