TCP/IP Stack Simulation

This project is a simple implementation of a TCP/IP stack simulation, focusing on Layer 2 and Layer 3 functionalities. It allows you to build network topologies, set routing entries, and perform basic networking operations.

Getting Started

Build the Project

To build the project, use the following command:

make build

Run the Project

Run the compiled executable with the following command:

./tcpip

Setting Routes

You can set routing entries using the config node route command. Here is an example:

config node route R1 122.1.1.3 32 10.1.1.2 eth0/1

Ping Operation

To ping a destination address, use the run node ping command. Example:

run node ping R1 122.1.1.3

You can also perform IP-in-IP encapsulation using the following command:

run node ping tunnel R1 <destinationIP> <tunnelIP>

Additional Functionalities

• VLAN Support: Create and manage VLANs for network segmentation.
• Loopback Address: Assign loopback addresses to nodes for local testing.

Topology Customization

In the topology/topology.go file, you can create your own topology. Use the created topology in the cmd/commands.go file by calling the function you created to replace the variable topology with the returned topology.

Future Development

This simulation is a work in progress, and more features will be added in the future.

Feel free to explore the code and experiment with different network topologies!
