# Backend - Queueing Network Simulation

Python FastAPI backend for simulating distributed database queueing networks.

## Setup

1. Create a virtual environment:
```bash
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
```

2. Install dependencies:
```bash
pip install -r requirements.txt
```

## Running

Development mode:
```bash
python src/main.py
# or
uvicorn src.main:app --reload
```

The API will be available at `http://localhost:8000`

API documentation: `http://localhost:8000/docs`

## Testing

```bash
pytest tests/
```
