Let
D
(
n
) and
H
(
n
) be the fractal dimension and the Hurst parameter of traffic in the
n
th interval, respectively. Thus, this paper gives the experimental variance analysis of
D
(
n
) and
H
(
n
) of network traffic based on the generalized Cauchy (GC) process on an interval-by-interval basis. We experimentally infer that traffic has the phenomenon Var[
D
(
n
)] > Var[
H
(
n
)]. This suggests a new way to describe the multifractal phenomenon of traffic. That is, traffic has local high-variability and global robustness. Verifications of that inequality are demonstrated with real traffic.
