Subsequent multipath routers select a random outgoing interface and random forwarding state descriptor (FSD) and temporarily correlate the selected random outgoing interface with the FSD and add the FSD to the probe message. The probe messages provide different destinations with various hidden paths. Each hidden path enables forwarding of packets from probing middle-boxes to the destination without identifying any routable address en-route to the destination. The destination then provides a data source with the hidden path.
