В качестве метода выделения регулярного тренда сетевого трафика используется вейвлет-регрессионная обработка временного ряда, обеспечивающая подавление высокочастотных возмущений и сохранение регулярной составляющей. Для выявления интервалов перегрузки применяется байесовский обнаружитель импульсных сигналов, формирующий селаженную импульсную последовательность апостериорных вероятностей превышения нормального режима. Для количественного описания каждого перегрузочного эпизода введена параметрическая модель импульса на основе еауссовой аппроксимации, позволяющая связать перегрузку с тремя измеримыми характеристиками: амплитудой, длительностью и интегральной площадью. Дополнительно предложены нормализованные показатели параметров относи- тельно статистики нормального режима и интегральный критерий отклонения, обеспечивающий оценку выраженности перегрузочного состояния.</p></sec><sec><title>Резулытаты</title><p>Резулытаты. Получены критерии и правила классификации перегрузок по пяти типам: импульсная, фоновая, прогрессирующая, периодическая и атакующая. Результаты имитационного моделирования на данных с различными режимами нагрузки показали работоспособность предложенного подхода: перегрузочные эпизоды выделяются устойчиво, а типизация соответствует ожидаемой структуре сценариев. Выявлены особенности реакции вероятностного обнаружителя на плавно нарастающую нагрузку, способную проявляться как последовательность локальных импульсов.</p></sec><sec><title>Заключение</title><p>Заключение. Разработанная методика обеспечивает переход от визуальной интерпретации выходного сигнала байесовского обнаружителя к количественной оценке и типизации перегрузок и может применяться в задачах автоматизированного мониторинга сетевого трафика и поддержки решений по управлению качеством обслуживания в многомашинных вычислительных системах.</p></sec></abstract><trans-abstract xml:lang="en"><p>The purpose of the research is to develop criteria for detecting and classifying overloads occurring in multi-machine computing systems based on network traffic data based on an analysis of its regular trend and subsequent probabilistic interpretation of the overload state.</p><sec><title>Methods</title><p>Methods. The wavelet regression processing of the time series is used as a method for detecting the regular trend of network traffic, which ensures the suppression of high-frequency disturbances and the preservation of the regular component. To identify overload intervals, a Bayesian pulse signal detector is used, which generates a smoothed pulse sequence of a posteriori probabilities of exceeding the normal mode. To quantify each overload episode, a parametric pulse model based on Gaussian approximation is introduced, which makes it possible to associate overload with three measurable characteristics: amplitude, duration, and integral area. Additionally, normalized parameter indicators relative to normal mode statistics and an integral deviation criterion are proposed, which provides an assessment of the severity of the overload condition.</p></sec><sec><title>Results</title><p>Results. Criteria and rules for classifying overloads into five types are obtained: impulse, background, progressive, periodic and attacking. The results of simulation modeling on data with different load modes showed the efficiency of the proposed approach: overload episodes are consistently highlighted, and the typing corresponds to the expected structure of scenarios. The features of the probabilistic detector’s response to a smoothly increasing load, which can manifest itself as a sequence of local pulses, are revealed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed technique provides a transition from visual interpretation of the Bayesian detector output signal to quantification and typification of congestion and can be used in tasks of automated monitoring of network traffic and support for quality-of-service management solutions in multi-machine computing systems.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сетевой трафик</kwd><kwd>перегрузка</kwd><kwd>вейвлет-регрессия</kwd><kwd>вероятностное реле</kwd><kwd>критерии классификации</kwd><kwd>апостериорная вероятность</kwd><kwd>классификация аномалий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>network traffic</kwd><kwd>overload</kwd><kwd>wavelet regression</kwd><kwd>probabilistic relay</kwd><kwd>classification criteria</kwd><kwd>posterior probability</kwd><kwd>anomaly classification</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Данная работа финансировалась за счет средств бюджета в рамках государственного задания Министерства науки и высшего образования РФ № FSWF-2025-0010 «Разработка научно-технических основ создания программных и аппаратных решений для управления объектами энергетики с использованием цифровых двойников и технологий искусственного интеллекта».</funding-statement><funding-statement xml:lang="en">This work was financed from the budget within the framework of the state task of the Ministry of Science and Higher Education of the Russian Federation No. FSWF-2025-0010 "Development of scientific and technical foundations for creating software and hardware solutions for managing energy facilities using digital twins and artificial intelligence technologies".</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Петушков Г.
