Paper Abstract

Measurements of file sizes transported on the WWW have led some researchers to propose describing them by probability distributions with infinite variance. The M/G/1 queue often arises as a performance model for components of the WWW, and the service times correspond to file sizes; the infinite variance of the file sizes becomes the variance of the service times. In this paper the effects of very large service-time variance on some performance measures for the M/G/1 queue are explored via numerical examples and analytic arguments.
