Cloonix vs OMNeT++

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.

OMNeT++ is a modular C++ simulation library and framework used mainly to build network simulators. Its discrete-event models consist of communicating C++ modules whose structure is defined in the NED language. Simulations can run in Qtenv, a graphical runtime environment, or Cmdenv, a command-line interface. The IDE Analysis Tool uses Pandas and Matplotlib to analyze and plot results; R and Matlab can also process them. Extensions cover real-time simulation, network emulation, database integration, and SystemC integration, while the INET model library provides Internet stack models and other protocols and components. Packages are offered for Linux, Windows, and macOS, along with a core archive and container images. The project recommends opp_env for installation and uses WSL in its recommended Windows route. Its Academic Public License allows noncommercial teaching and research; commercial work requires a separate license, priced on request. The maker says the software has no telemetry or account system and keeps models and results on the user's computer.
