The Hurst parameter H, is one key measure of self-
similarity [8], [9] for an underlying process and commonly
used to estimate the long-range dependence of a stochastic
process. A Hurst parameter of H = 0.5 indicates absence
of self-similarity whereas H = 1 indicates long-range depen-
dence. We additionally note that while the Hurst parameter is
mathematically well-defined, its determination is not clearly
defined, but commonly performed through estimations, see,
e.g., [10]. We employ the R/S statistic [11]–[13] to estimate
the Hurst parameter for the captured traffic. Specifically, we
estimate the Hurst parameter H as the slope of a log-log
plot (also referred to as pox plot or adjusted scaled range
plot) of the R/S statistic using a least squares fit. In addition,
we calculate the Hurst parameter using the technique outlined
in [14] as an additional metric. For a more visual approach
to the identification of network bandwidth usage and its self-
similarity, we utilize the autocorrelation function, see, e.g.,
[15].
