ns-3 is a free, discrete-event network simulator for research and education. It supports simulations of IP and non-IP networks, including wireless work involving Wi-Fi and LTE, and provides a workflow from configuring a simulation through collecting and analyzing traces. A real-time scheduler supports simulation-in-the-loop use, including sending and receiving ns-3 packets on real network devices. Its Direct Code Execution framework can run C or C++ applications or the Linux kernel networking stack within ns-3.

The project is available for Linux, macOS, Windows, and self-hosted use, with desktop deployment listed. It is free software under GNU GPLv2, priced at free.
