Application of Computer Network Simulation Software in Virtual Environment

The development of information technologies enabled interactive teaching and the application of various software in education. The paper analyzed problems observed in the standard way of teaching in the field of computer networks. The aim of this paper is to prove that the application of computer network simula- tion software in teaching can improve the understanding of the materials in the field of computer networks. A comparative analysis of three computer network simulation software (Cisco Packet Tracer, GNS3 and OPNET) was performed regarding of use of these software in teaching. It is shown why Cisco Packet Tracer is the best solution for entry-level education in this area. By creating a simple computer network using Cisco Packet Tracer software, the necessary initial theoretical knowledge of computer networks is presented. It has been shown that the application of computer network simulation software cannot replace the classical form of teaching but represents good support in mastering complicated theoretical concepts in the field of computer networks.
