Patent ID: 7720004

Claim:
A method comprising: transmitting a first stream of packets in a first temporal pattern from a first node n 1 to a second node n 2 via a first path p 1,2 in a packet network; transmitting a second stream of packets in a second temporal pattern from a third node n 3 to a fourth node n 4 via a second path p 3,4 in the packet network; receiving the first stream of packets at the second node n 2 in a third temporal pattern, wherein the third temporal pattern is different from the first temporal pattern; deducing that the first path p 1,2 and the second path p 3,4 intersect at a fifth node n 5 when the first stream of packets as received at the second node n 2 exhibits interference corresponding to the second temporal pattern; and transmitting a packet in the packet network to transit the fifth node n 5 ; wherein the interference of the first stream of packets by the second stream of packets is manifested as correspondence between the third temporal pattern and the second temporal pattern.
