Query: Using the Modified Allan Variance for Accurate Estimation of the Hurst
  Parameter of Long-Range Dependent Traffic   Internet traffic exhibits self-similarity and long-range dependence (LRD) on
various time scales. A well studied issue is the estimation of statistical
parameters characterizing traffic self-similarity and LRD, such as the Hurst
parameter H. In this paper, we propose to adapt the Modified Allan Variance
(MAVAR), a time-domain quantity originally conceived to discriminate fractional
noise in frequency stability measurement, to estimate the Hurst parameter of
LRD traffic traces and, more generally, to identify fractional noise components
in network traffic. This novel method is validated by comparison to one of the
best techniques for analyzing self-similar and LRD traffic: the logscale
diagram based on wavelet analysis. Both methods are applied to pseudo-random
LRD data series, generated with assigned values of H. The superior spectral
sensitivity of MAVAR achieves outstanding accuracy in estimating H, even better
than the logscale method. The behaviour of MAVAR with most common deterministic
signals that yield nonstationarity in data under analysis is also studied.
Finally, both techniques are applied to a real IP traffic trace, providing a
sound example of the usefulness of MAVAR also in traffic characterization, to
complement other established techniques as the logscale method.
