Overview

This program simulates a network environment with a hierarchical tree topology, consisting of a router, switches, and PCs. It allows administrators and users to interact with the network, monitor traffic, manage devices, and simulate network attacks such as DDoS. The program is designed to run in a console environment with a menu-driven interface for both administrators and users.

Features

Administrator Features

• Add/Remove PCs: Connect or disconnect PCs to/from switches.
• Change Configuration: Modify IP addresses and gateways of PCs, switches, and the router.
• Start/Stop Devices: Control the power state of devices (PCs, switches, router).
• Simulate DDoS Attacks: Launch and mitigate DDoS attacks on network devices.
• Monitor Network: Display network topology, logs, registered IPs, bandwidth usage, and adjacency list.
• Process Packets: Administer the processing of network packets queued for delivery.

User Features

• Send/Receive Packets: Transmit messages to other PCs and view received packets.
• Ping Router: Check connectivity and measure round-trip time to the router.
• View Bandwidth Usage: Display the bandwidth usage of the user's PC.
• Block/Unblock IPs: Manage blocked IP addresses to control access.
• Start/Stop PC: Turn the user's PC on or off.

Network Topology

The network is structured in a tree topology with the following hierarchy:

• Router: Central device connecting multiple switches.
• Switches: Intermediate devices connecting multiple PCs.
• PCs: End devices connected to switches.

Logging

The program logs all significant events and actions, including device status changes, packet transmissions, DDoS attacks, and user actions. Logs are stored both in memory and written to a file (network_logs.txt).

Simulation Details

Packet Handling

• Packets are enqueued for processing and can be accepted or rejected by the administrator.
• Bandwidth usage is tracked for both sent and received packets.

DDoS Simulation

• DDoS attacks can be simulated by generating a large number of packets from multiple sources to a target IP.
• Mitigation involves shutting down the target device and the sources of the attack.

Tree Topology Display

• The network topology is displayed in a hierarchical tree format, showing the router, switches, and connected PCs.

Usage

Administrator Mode:

• Login with username admin and password admin.
• Use the menu to configure the network, monitor traffic, and simulate attacks.

User Mode:

• Login with the username and password assigned to the connected PC.
• Use the menu to send/receive packets, ping the router, and manage the PC.

File Structure

• networkTrafficMonitoringSimulation.cpp: this one implement graph structure, a bit fragile.
• networkTrafficMonitoringSimulationTanpaGraf.cpp: This one without implementation of graph structure, more stable.
• network_logs.txt: Log file to store network events.
