About:
ns-3 is a discrete-event network simulator used for research and education. It provides a realistic environment for simulating TCP/IP, routing, and application performance, enabling detailed protocol analysis and experimentation.
Key Features:
  • High-fidelity simulation of TCP/IP stacks
  • Extensive library of network protocols and models
  • Python bindings for scripting and integration
  • Support for real-time emulation and logging
Use Cases:
  • Researching and developing new network protocols
  • Evaluating network performance under various conditions
  • Teaching computer networking concepts
Alternatives:
  • OMNeT++ – OMNeT++ is a modular C++ simulation framework with a strong GUI, whereas ns-3 is specifically focused on IP network simulation.
  • Mininet – Mininet creates real network topologies using Linux containers for live testing, while ns-3 provides a purely virtual discrete-event simulation.
