Modern telecommunications are unimaginable without networking with different protocols and layers, and, accordingly, specific hardware and software resources. The study course is focused on the software part of computer networks and provides knowledge on different programmes and tools to be used for different purposes. These purposes include, but are not limited to, network monitoring, network security, network topology design, and machine learning applications. All these topics are covered by the study course. By the end of the study course, students are expected to have solid skills for further working with networks and traffic software to continue their research or career in this direction.
