I agree it is useful but one can construct hypothetical traces with the
same CoV representing a constant linear increase (perfectly smooth) and
sin wave of arbitrary frequency. So perfectly smooth traffic and very
ill-behaved traffic can have identical CoV. (But one can construct
similar counter examples with almost any measure picked).
Wischik and Ganesh's concept of Hurstiness is a mathematically rigorous
quantity developed for analysing the burstiness of traffic queues which
has some attractive known results for buffer asymptotics.
