Рябко. Показывается и анализируется зависимость итоговой оценки от различных параметров: объема кэширующих серверов, а также скорости канала передачи данных между клиентом и оригинальным сервером. На основе полученных расчетных данных делается вывод о логическом соответствии результатов вычислений характеру изменений, вносимых в параметры сети, показывается адекватность аналитической оценки.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, problem solving of analytic estimation of data-transmission network efficiency based on the method proposed by B.Ya. Ryabko is considered. Dependence of the channels speed estimation, caching servers volume, and network configuration is demonstrated and analyzed. A conclusion about logical correspondence between computational results and the character of network alterations based on the obtained results is drawn and so adequateness of the analytic estimation method is experimentally demonstrated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сети передачи данных</kwd><kwd>оценка эффективности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>data-transmission network efficiency</kwd><kwd>estimation efficiency</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">Ryabko B.
