The Effect of Multiple Time Scales and Subexponentiality in MPEG Video Streams on Queueing Behavior

Abstract

Guided by the empirical observation that realtime MPEG video streams exhibit both multiple time scale and subexponential characteristics, we construct a video model that captures both of these characteristics and is amenable to queueing analysis. We investigate two fundamental approaches for extracting the model parameters: using sample path and second-order statistics-based methods. The model exhibits the following two canonical queueing behaviors
