Abstract

Consider a multimedia input traffic stream, described by a stationary random process. Our previous study indicates that second-order input statistics, which are described by a power spectrum in the frequency domain, play a dominant role in queueing performance as compared with higher-order input statistics. In this paper, we show the significant effect of an input power spectrum on link capacity allocation in a finite-buffer system to achieve a desired performance criterion. The study also explores a fundamental limit of buffer sizing to improve link capacity when traffic contains significant low-frequency power.
