Open-source network simulation roundup 2024
As of early 2024, my list of network simulation and emulation tools remains stable. This post provides the latest status of the tools I list in this blog.

Network simulators for high-school teachers
A list of network simulators that meet the unique requirements of educators in secondary schools, who teach students aged 14 to 18.
Twenty-five open-source network emulators and simulators you can use in 2023
I reviewed the development and support status of all the network emulators and network simulators previously featured in my blog, as of early 2023.
Use Containerlab to emulate open-source routers
This post will review how the Containerlab network emulator works with the FRR open-source router.
How to simulate an IPv6 network using the cloonix network simulator
As we work through this tutorial, we will learn how to use the cloonix graph interface to build a simulation scenario that includes two small IPv6 networks connected to each other by two routers via static routes. We will also learn how cloonix saves network topologies and guest virtual machine root filesystems. The cloonix open-source
Upgrade a guest VM in the cloonix network simulator
The cloonix project provides a variety of root filesystems for use in the cloonix network simulator. These root filesystem only have the most basic software packages installed and will not support advanced network configuration (with the exception of router filesystems such as openwrt). To create a network simulation that runs real-world networking software, we need
Cloonix network simulator v24: what’s new
The cloonix development team recently updated the cloonix network simulator to version 24. This post describes the changes in cloonix v24 compared to cloonix v19, which we reviewed in a previous post. Version 24 simplifies the setup of guest virtual machines, improves the link performance emulation tool, and adds new interface types designed to improve
Install Cloonix v24
The Cloonix open-source network simulator was recently updated to version 24. The last time I used Cloonix, it was at version 19 (see my review of Cloonix and my using the Cloonix graph interface posts). Compared to version 19, only a few details of the installation procedure have changed — the list of package dependencies
Eliminate garbage data in the CORE Network Emulator
While working through some of the previous tutorials about the CORE Network Emulator or IPv6, we noticed some strange broadcast packets in the Wireshark packet analyzer that appeared to have nothing to do with the processes running on the simulated network. For example, we started a simulation consisting of two nodes connected to the same
IMUNES network simulator test drive
The Integrated Multiprotocol Network Emulator/Simulator (IMUNES) is a fast, functional network simulator that runs on the FreeBSD operating system. It was created by a team of researchers and educators at the University of Zagreb. The IMUNES development team offers a VirtualBox image of a FreeBSD system with IMUNES installed so it is easy to evaluate.
CORE Network Emulator test drive
The Common Open Research Emulator (CORE) is an open-source network simulator developed by Boeing’s Research and Technology division and supported, in part, by the US Naval Research Laboratory. It is a fork of the IMUNES Network Emulator project and it was developed as a tool to support a mobile data networking research project. It can
Using Netkit pre-configured labs
The Netkit open-source network simulator was created by a group of university professors who use it as a tool in their teaching. They created a large number of pre-configured lab scenarios, each with lecture slides that describe the scenario and the technology used in the scenario, and make these assets available on the Netkit web
