Abstract
An apparatus for in-band telemetry includes a node type identifier circuit that, in response to receiving an ingress/egress ID command, determines that the network node is an ingress node in response to the network node having a direct connection to a source and determines that the network node is an egress node in response to the network node having a direct connection to a destination. The apparatus includes a telemetry packet circuit that creates a telemetry packet in response to the node type identifier circuit determining that the network node is an ingress node. The apparatus includes a telemetry transmission circuit that transmits the telemetry packet in response to the telemetry packet circuit creating the telemetry packet and a packet re-router circuit that, in response to the node type identifier circuit determining that the network node is an egress node, routes a received telemetry packet to a network controller.
