Is Network Traffic Appriximated by Stable Lévy Motion or Fractional Brownian Motion?
Is Network Traffic Appriximated by Stable Lévy Motion or Fractional Brownian Motion?
Cumulative broadband network traffic is often thought to be well modeled by fractional Brownian motion (FBM). However, some traffic measurements do not show an agreement with the Gaussian marginal distribution assumption. We show that if connection rates are modest relative to heavy tailed connection length distribution tails, then stable Lévy …
