Abstract
Systems, methods, and computer-readable media are disclosed for identifying a source of congestion in a network using postcard-based telemetry. Sampled packets from a packet flow are received by a network management collector The packet flow emanates from a host into a network ingress point of an ingress networking device. The packet flow flows through a network made up of intermediate networking devices and terminates at a network egress point. At least a portion of the one or more sampled packets is analyzed to determine whether a congestion indication has been set by a networking device. In response to determining that the congestion indication has been set a congestion notification is provided to a network administrator. The congestion notification provides an indication that the networking device has detected network congestion.
