Network Simulator

Overview

Network Simulator is a Java-based application that simulates a basic network topology. It allows users to add main devices (Hub, Switch, Router) and end devices, create connections between them, and send messages within the network. This simulator is designed to provide a simple stimualtion.

Features

• Add main devices: Hub, Switch, Router.
• Add end devices and automatically connect them to all main devices.
• Visualize the network topology with links between devices.
• Send messages between devices with acknowledgment.
• Clear all devices and reset the topology.
