Abstract
A method includes sending over the network from a source entity to a destination entity a sequence of a plurality of packets. Each packet in the sequence includes a same identifier corresponding to a network entity on the network. Sending includes modifying a property of the sequence of packets to uniquely identify the sequence of packets. The method includes receiving information indicating the identifier corresponds to the modification of the property. Another method includes examining a sequence of packets sent over a network from a source entity to a destination entity, each packet in the sequence comprising a same identifier corresponding to a network entity on the network. The method includes determining whether a property of the sequence of packets was modified when sent to uniquely identify the sequence of packets; and responsive to the determining, associating the identifier with the network identity. Apparatus and program products are also disclosed.
