Modeling and Simulation Tools for Studying Computer Networks: Overview and Practical Experience

Abstract

Simulation and modelling can play an essential role in studying computer networks. These tools help students study the behaviour of the network and compare its performance indicators during different scenarios of operation without requiring special equipment. However, the process of integrating modelling and simulation tools into network courses usually depends on the topic of the training course or the personal preferences of the teacher, which may not meet the requirements of the training of a future specialist. Combining theory and practice in one course of studying computer networks is extremely difficult due to the constant increase in the complexity and scale of modern networks. This was one of the main reasons for writing the current scientific work, during which the functionality of the most popular network simulators was considered, and the advantages and disadvantages of each of the considered tools were also mentioned, which helped to analyse the possibility of using each of them in the process of studying networks. Our recommendations for effectively implementing these tools in the learning process are provided. These recommendations can be used both at the level of schools and lyceums and in higher education institutions (HEIs), making them universal. The issue of changing approaches in domestic education to the process of studying computer networks is determined to be relevant for future research since, due to the technological revolution and the rapid development of information technologies, which has been going on for the past several decades, educational material loses its relevance every year, and networks, on the contrary, are becoming more and more complex.
