description A method and system for flow tracing for use in a packet-optical network is disclosed herein. A device in the packet-optical network may receive a packet including a header and payload. The device may read intent information from the header, and translate the intent information to generate a device-specific action in an optical layer to provide one or more globally unique identifiers (IDs) associated with the device. The device may execute the device-specific action in the optical layer to generate a response including the globally unique IDs corresponding to the intent, where the response forms part of the flow trace. The device may associate the response with the intent, and encode the response for downstream data forwarding. The device may further add multi-layer proof-of-transit (POT) information to the response that may be used to securely verify the path indicated in the SmartFlow flow trace.
