Correlative features of queue size in queue systems with general flows

This work describes queue systems with request train flows being typical for modern multiservice networks. Influence of correlation features of flows on queue sizes is shown. Here the expression for correlation was derived. It generalizes a well known Pollaczek-Khinchin formula and it is correct for any stationary and ordinary request flows. Therefore average queue size is defined by dispersion and sum of correlative parameters of requests over service cycle. Flow parameters are easy determined by experiment. They can be used further for computing of average queue size in multiservice communication systems.
