Learning Stages

Stage 1: Foundation

Understand the daemon, clients, and basic message flow by experimenting with and then building a mock simulator.

Stage 2: Real Topologies

Create custom network topologies and handle realistic shortest-path routing scenarios with NetworkX.

Stage 3: Advanced Integrations

Connect to production-grade network simulators — ns-3 in System-Wide mode, and OMNeT++ (basic and with INET) in Per-Node mode.
