Getting Started Tutorial

This tutorial walks you through using Claude Code to explore and understand FUSION.

Step 1: Understand the Project Structure

Start by getting an overview of how FUSION is organized:

> What are the main modules in FUSION and what does each one do?

Claude will explain the directory structure and the purpose of each major component.

FUSION deals with optical networking concepts that may be unfamiliar. Ask Claude to explain:

> Explain what RSA (Routing and Spectrum Assignment) means and how FUSION implements it.

> What is spectrum fragmentation and why does it matter?

When you need to locate specific functionality:

> Where is the main simulation loop? Show me the key functions.

> Which file handles network topology loading?

Learn the practical aspects of using the simulator:

> How do I run a basic simulation with FUSION? Walk me through the steps.

> What configuration options are available and where do I set them?

When you’re ready to contribute or modify the code:

> I want to add a new routing algorithm. What files do I need to modify and what interfaces should I implement?

> Show me an example of an existing routing algorithm so I can follow the same pattern.

If you encounter problems:

> The simulation is giving high blocking probability. What should I check?

> I'm getting an error in the spectrum assignment module. Help me understand this traceback.
