This project demonstrates the design, implementation, and validation of a large-scale enterprise network environment using Cisco Packet Tracer. The simulated infrastructure integrates enterprise networking, ISP backbone connectivity, cloud-hosted services, web applications, RFID systems, and Internet of Things (IoT) devices into a unified architecture.
The environment was designed to model how modern organizations connect users, applications, cloud resources, and smart devices across multiple interconnected networks. The project incorporates LAN and WAN connectivity, routing and switching infrastructure, DNS services, HTTP services, cloud-hosted applications, and centralized IoT device management.
