The proposed algorithm is based on finding the coefficients of the Haar wavelet transformation coefficient. An experimental analysis, presented demonstrates that an increase in the delay and the level of packet losses during video transmission over the network is closely related to an increase in the value of the autocorrelation coefficients of time intervals between packets at the traffic source output. The algorithm's performance is checked both on the resulting experimental trace and on the generated time intervals with the predetermined correlation coefficient, the value of which significantly exceeds the experimental value. The result of the proposed algorithm is new time intervals with a significantly reduced autocorrelation degree (almost equal zero).</p></abstract><trans-abstract xml:lang="ru"><p>Статья посвящена разработке и исследованию алгоритма декорреляции сетевого трафика, позволяющего существенно снижать значения коэффициентов автокорреляции интервалов времени между пакетами. В основе предлагаемого алгоритма лежит нахождение коэффициентов вейвлет-преобразования Хаара. Проводится экспериментальный анализ, показывающий, что увеличение задержки и уровня потерь пакетов при передаче видео по сети тесно связано с повышением значения коэффициентов автокорреляции интервалов времени между пакетами на выходе источника трафика. Проверка работоспособности алгоритма осуществляется как на полученной в результате эксперимента трассе, так и на сгенерированных интервалах времени с заданным коэффициентом корреляции, значение которого существенно превосходит значение экспериментального. Результатом работы предлагаемого алгоритма являются новые интервалы времени, обладающие существенно сниженной, практически отсутствующей, автокорреляцией.</p></trans-abstract><kwd-group xml:lang="en"><kwd>network traffic</kwd><kwd>decorrelation</kwd><kwd>autocorrelation function</kwd><kwd>network latency</kwd><kwd>Haar wavelets</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>сетевой трафик</kwd><kwd>декорреляция</kwd><kwd>автокорреляционная функция</kwd><kwd>сетевая задержка</kwd><kwd>вейвлеты Хаара</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Cisco.
