These services generate traffics of three types - unicast streaming, multicast streaming and elastic traffics. In this paper, we propose a multi-servicemodel of a triple play single-link network; we obtained an approximate formula for the stationary probability for the model; and finally, we find an exact algorithm for calculating performance measures by reducing the dimension of the problem.</abstract><trans-abstract xml:lang="ru">Современные мультисервисные сети неразрывно связаны с коммерческой концепцией «тройная услуга», при которой пользователю по высокоскоростному каналу одновременно предоставляются три услуги - телефония, телевидение и передача данных Интернет. Трафик, генерируемый этими услугами, можно также разделить на три типа - одноадресный (unicast), многоадресный (multicast) и эластичный (elastic). В статье построена модель звена мультисервисной сети с тройной услугой, получена приближенная формула для стационарного распределения вероятностей состояний и предложен точный алгоритм для расчёта характеристик при помощи снижения размерности решаемой задачи.</trans-abstract><kwd-group xml:lang="en"><kwd>triple play</kwd><kwd>single-link</kwd><kwd>streaming traffic</kwd><kwd>unicast traffic</kwd><kwd>multicast traffic</kwd><kwd>elastic traffic</kwd><kwd>stationary probability distribution</kwd><kwd>approximation</kwd><kwd>exact algorithm</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>тройная услуга</kwd><kwd>звено сети</kwd><kwd>потоковый трафик</kwd><kwd>одноадресный трафик</kwd><kwd>многоадресный трафик</kwd><kwd>эластичный трафик</kwd><kwd>стационарное распределение</kwd><kwd>приближенный метод</kwd><kwd>точный алгоритм</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Hens F.
