RAN virtualization and division into logical subnetworks - slices - puts this task into a new perspective. In the paper we present a software tool based on the OMNeT++ platform and developed for performance analysis of a network slicing policy with SLA-based slice performance isolation. The tool is designed using the object-oriented approach, which provides flexibility and extensibility of the simulation model. The paper briefly presents the slicing policy under study and focuses on the simulator’s architecture and design. Numerical results are provided for illustration.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;">В настоящее время, несмотря на ввод в эксплуатацию сетей мобильной связи 5-го поколения, эффективное разделение ресурсов сети радиодоступа по-прежнему остаётся актуальной задачей. Свои коррективы в её постановку вносят технологии виртуализации и нарезки сети (network slicing), позволяющие разделять сеть доступа на логические подсети. В статье предложен инструмент имитационного моделирования, разработанный на платформе OMNeT++ для анализа эффективности схемы разделения ресурсов с изоляцией слайсов на базе соглашений об уровне обслуживания. Объектно-ориентированный подход к построению симулятора обеспечивает гибкость и расширяемость модели. В статье кратко изложена исследуемая схема слайсинга, подробно описана архитектура программного средства и особенности построения имитационой модели, приведены результаты численного анализа.</p></trans-abstract><kwd-group xml:lang="en"><kwd>queuing system</kwd><kwd>resource allocation</kwd><kwd>network slicing</kwd><kwd>simulation</kwd><kwd>optimization</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>система массового обслуживания</kwd><kwd>разделение ресурсов</kwd><kwd>нарезка сети</kwd><kwd>имитационное моделирование</kwd><kwd>оптимизация</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This paper has been supported by the RUDN University Strategic Academic Leadership Program.
