LINK CAPACITY ALLOCATION BY INPUT POWER SPECTRUM

Consider a multimedia input traffic stream, described by a stationary random process. Our previous study indicates that second-order input s tatistics, which are described by a power spectrum in the frequency do main, play a dominant role in queueing performance as compared with hi gher-order input statistics. In this paper, we show the significant ef fect of an input power spectrum on link capacity allocation in a finit e-buffer system to achieve a desired performance criterion. The study also explores a fundamental Limit of buffer sizing to improve link cap acity when traffic contains significant low-frequency power.
