Cloonix vs ns-3

Cloonix is a free, AGPLv3 suite of C software components for creating virtual networks with KVM-based virtual machines and containers. It runs as a user-land application on a Linux distribution, with a web platform also listed. Users assemble machines, containers, and network items, connect them through Open vSwitch bridges, and view the topology on a graphical canvas. Virtual machines use QEMU-KVM; crun containers can use ZIP files or directories as root filesystems. Elements include NAT, host TAP and physical interfaces, links between Cloonix networks, and packet transit for dropping, shaping, or delaying traffic. The project names Open vSwitch, crun, QEMU-KVM, SPICE, and Wireshark as key components. A Wireshark spy can display or save captures on supported interfaces but is not the complete Wireshark application. Wi-Fi emulation uses vwifi and iw. Installation offers a privileged bundle or cloonix-toy without root requirements. The homepage lists version 53.01, dated November 4, 2025.

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. Releases arrive roughly two or three times each year, mainly as compressed source archives. Documentation includes tutorials, installation guidance, model library material, a reference manual, and Doxygen API documentation. NetAnim and Bake are listed as related tools. Support channels include mailing lists, Zulip chat, and the issue tracker; the project says volunteers maintain it without company backing.
