    Abstract: In this disclosure, in a network comprising a plurality of network devices, a network device includes processing circuitry configured to: receive packet data corresponding to a network flow originating at a first device, the packet data destined to a second device; generate an entropy label to add to a label stack of the packet data, wherein the entropy label is generated from one or more attributes corresponding to the network flow that originated at the first device and is destined to the second device; generate a flow record including the entropy label, wherein the entropy label identifies the network flow amongst a plurality of network flows in the network; and send, to a controller of the network, the flow record, wherein the controller identifies the flow record based on the entropy label corresponding to the network flow originating at the first device and is destined to the second device.
