A device may obtain a flow signature, identify a destination collector to which packets bearing the flow signature are sent, obtain a list of potential source collectors that may have sent the packets bearing the flow signature to the destination collector, and identify a source collector, among the potential source collectors, that sent the packets to the destination collector. In addition, the device may output information related to a path from the source collector the destination collector. |

1. A method comprising:
identifying, by one or more devices, a flow signature; identifying, by the one or more devices, a destination collector to which packets, including the flow signature, are sent; identifying, by the one or more devices, a list of potential source collectors that are possible senders of the packets, including the flow signature, to the destination collector; sending, by the one or more devices, flow match requests to a plurality of devices associated with the list of the potential source collectors; receiving, by the one or more devices and from the plurality of devices, replies to the flow match requests; determining, by the one or more devices and based on the replies, a list of verified collectors among the potential source collectors; determining, by the one or more devices, that the list of verified collectors is not empty; identifying, by the one or more devices and based on determining that the list of verified collectors is not empty, a source collector that is identified in the list of verified collectors and that sent the packets to the destination collector; and outputting, by the one or more devices, information related to a path from the source collector to the destination collector. |
