Вот почему возникает потребность в замене ручной конфигурации сетевой инфраструктуры ЦОД автоматизированными средствами. Одним из перспективных направлений модернизации существующей архитектуры сети является концепция SDN. Программно-определяемый ЦОД – это виртуализированная структура, направленная на предоставление услуги. Именно в рамках этой концепции необходимо развивать методы управления трафиком и балансировки внутри сетей ЦОД. В статье представлена математическая модель динамического алгоритма балансировки нагрузки в сетях ЦОД.</p></abstract><trans-abstract xml:lang="en"><p>In regard with the increasingly complex topology of the network infrastructure of data centers and its requirements of performance, reliability and fault tolerance, the complexity of managing network infrastructure of the data center are also constantly growing. In this regard, there is a need to modification manual configuration of the network infrastructure of data centers by automated means. One of the perspective directions of modernization of the existing network architecture is the concept of SDN. Software-defined data center (Software Defined Data Center, SDDC) is a virtualized structure aimed at providing services. Within this concept it is necessary to develop methods of traffic management and balancing within the data center networks. The article presents a mathematical model of the dynamic load balancing algorithm in data center networks.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ЦОД</kwd><kwd>программно-конфигурируемые сети</kwd><kwd>SDN</kwd><kwd>дата-центр</kwd><kwd>динамическая балансировка нагрузки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Data center</kwd><kwd>software defined networking</kwd><kwd>SDN</kwd><kwd>dynamic load balancing</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">Vladyko A., Letenko I., Lezhepekov A., Buinevich M.
