This project aims to design and implement a basic network simulator in Java to visualize packet forwarding between devices in a simple network topology. It will also focus on understanding IP addressing, subnet masking, and basic routing concepts.

Project Requirements:

$1.$ Network Topology $(5$ points$)$:

$-$ Create a network topology with at least $5$ devices $($routers and hosts$).$

$-$ Assign IP addresses and subnet masks to each interface.

$-$ Implement static routing to determine the next hop for packets.

$2.$ Packet Forwarding $(5$ points$)$:

$-$ Simulate packet forwarding between devices based on routing tables.

$-$ Implement packet loss and delay.

$-$ Visualize packet movement on the network topology.

$3.$ User Interface $(5$ points$)$:

$-$ Create a user$-$friendly interface to:

$-$ Define the network topology.

$-$ Assign IP addresses and subnet masks.

$-$ Start and stop simulations.

$-$ Visualize network traffic.

Additional Considerations:

$-$ Error Handling: Implement robust error handling to handle invalid input and unexpected behavior.

$-$ Documentation: Provide clear documentation, including code comments and a user manual.

Tips for Success:

$-$ Start Simple: Start with a small network topology and gradually increase its complexity.

$-$ Leverage Existing Libraries: Use libraries like JavaFX or Swing for visualization.

$-$ Test Thoroughly: Write unit tests to ensure the correctness of each component.

Deliverables: Your code including the Network Simulator and a PDF explaining your code. Code submission with no PDF mean $0.$
