ns-3

ns-3 is a discrete-event network simulator used for research, education, and development in computer networking. It models network protocols, devices, and traffic to simulate and analyze network behavior in a controlled environment. It is widely used in academia and industry for testing new networking concepts without physical hardware.

Also known as: ns3, Network Simulator 3, ns-3 simulator, ns3 network simulator, ns-3 discrete-event simulator

Why learn ns-3?

Developers should learn ns-3 when working on network protocol design, performance evaluation, or network research projects, as it allows for scalable and reproducible simulations. It is particularly useful for simulating complex network scenarios like IoT systems, 5G networks, or ad-hoc networks, where real-world testing is costly or impractical.
