BUILDING THE SIMULATION MODEL OF DIGITAL COMMUNICATION NETWORKS: A NEW APPROACH IN THE CISCO PACKET TRACER ENVIRONMENT

This article describes the process of creating and optimizing a simulation model of a digital communication network. New methodologies aimed at improving network efficiency, ensuring security, and optimizing performance in the CISCO Packet Tracer simulation environment are introduced. The model integrates QoS, VLAN, OSPF protocols, and network security mechanisms. The effectiveness of the new approach is demonstrated through experiments and results. The article presents both scientific analysis and practical outcomes.
