Abstract
A packet trace is received. The packet trace is transformed into a sequence of pulse signals in a temporal domain. The sequence of pulse signals in the temporal domain is transformed into a sequence of pulse signals in a frequency domain. Peaks are detected within relevant frequency bands in the sequence of pulse signals in the frequency domain. A fundamental frequency is identified within the peaks. The fundamental frequency, which represents the TCP flow clock, is returned.
