С использованием методов теории  массового обслуживания показано, что применение модели однородного потока, в частности формулы Кингмана, приводит к недооценке среднего времени пребывания пользовательских  запросов в системе на один-два порядка при высоком коэффициенте использования  исследуемого узла. Напротив, использование альтернативной суперстатистической модели,  учитывающей эффекты долговременной зависимости интенсивностей пользовательских запросов, позволяет снизить указанную недооценку более чем на один порядок.</p></abstract><trans-abstract xml:lang="en"><p>A superstatistical approach that takes into account the long-term correlation and the non-stationary dynamics is proposed fo r modelling  aggregated traffic with non-stationary dynamics. By means of queuing  system simulation, it is shown that traditional approximation based on  Kingman's formula underestimates the average sojourn time by up to two decades at high utilization. On the contrary, the use of  alternative superstatistical model taking into account the longterm correlation, this underestimation can be reduced by more than one decade.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Сетевой трафик</kwd><kwd>долговременная зависимость</kwd><kwd>производительность СМО</kwd><kwd>суперстатистики</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Network Traffic</kwd><kwd>Long-Term Correlation</kwd><kwd>Performance of Queuing System</kwd><kwd>Superstatistics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Park K., Willinger W.
