Claim One:
1. A method comprising: receiving, by a first node n 1 in a packet network, a first stream of packets; generating, by the first node n 1 , a jitter pattern based on the first stream of packets, wherein the jitter pattern comprises one or more temporally-shifted packets, and wherein generating the jitter pattern comprises: (1) identifying the one or more temporally-shifted packets in the first stream of packets, (2) grouping the one or more temporally-shifted packets that are within E seconds of one another into m groups, wherein m is a positive integer and E is a real number, and (3) computing the m−1 inter-group intervals to generate the jitter pattern; comparing, by the first node n 1 , the jitter pattern to a temporal pattern; and transmitting a packet in the packet network to transit at least one of: (a) a second node n 2 and not transit a third node n 3 when the jitter pattern corresponds to the temporal pattern; and (b) the third node n 3 and not transit the second node n 2 when the jitter pattern fails to correspond to the temporal pattern.
