A Python-based simulation of a Network Load Balancer that demonstrates traffic routing, failure handling, and server health monitoring using customizable load balancing strategies.
- 🔁 Load balancing using:
- Round Robin
- Least Connections
- IP Hashing
- 🩺 Server health monitoring with periodic health checks
⚠️ Simulated server failure and failover- 👥 Client request simulation
- 🖥️ Interactive and modern web-based GUI (Flask + Tailwind)
- 📜 Real-time logging and file-based logs
- 🧵 Concurrency handled using Python threading
The project was built to provide a visual, interactive simulation of load balancing for academic and educational purposes. It aims to bridge the gap between theoretical networking concepts and their practical applications in modern distributed systems.
- Python 3
socket,threading,logging(standard libraries)
- Flask – for the backend web server
- HTML + Tailwind CSS – for the frontend UI
- Concurrency – via Python threading
- Logging – both live and file-based logs
- Traffic Distribution using custom algorithms
- Server Failure Simulation with control over failure rates
- Client Simulation with configurable load
- Health Check Daemon for backend server status
- GUI to:
- Select algorithm
- Define number of servers/clients
- Tune failure and health check frequency
- View live logs and status
