Abstract
Disclosed are methods and systems that include presenting signals corresponding to a time-series of traffic on links of a network to a band-pass filter to obtain band-limited signals, the band pass filter centered substantially about a frequency corresponding to traffic to be tracked, determining coherence values of the band-limited signals, and, based on a comparison of the coherence values to a threshold, forming at least one map of the routing of the traffic based on the corresponding links.
