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.
