open-source network simulation tools that run on Linux or BSD systems
The Cloonix network emulator continues to be actively developed. In version 53, it provides container support, a rootless installation option, experimental support for WiFi emulation, and a simplified user experience.
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.
A list of network simulators that meet the unique requirements of educators in secondary schools, who teach students aged 14 to 18.
I reviewed the development and support status of all the network emulators and network simulators previously featured in my blog, as of early 2023.
This post will review how the Containerlab network emulator works with the FRR open-source router.
Antidote is the network emulator that runs the labs on the Network Reliability Labs web site. You may install a standalone version of Antidote on your personal computer using the Vagrant virtual environment provisioning tool. In this post, I show you how to run Antidote on a Linux system with KVM, instead of VirtualBox, on
I want to show you how to configure a host server so, when it is shut down, it executes a script that runs commands on any running virtual machines before the host tries to stop them. I will configure the host server to wait until the script completes configuring the virtual machines before continuing with
Yesterday, I participated in a screen-cast with Derick Winkworth, aka @CloudToad, to discuss my blog posts about installing NRE Labs Antidote network emulator on your PC and creating lessons for NRE Labs. We also covered some general points like contributing to communities, how to get started blogging about technical topics, and more. Check it out,
The Antidote network emulator, part of the Network Reliability Engineering project, offers a web interface that presents network emulation scenarios to users as documented lessons. Each lesson is presented in a window running Jupyter Notebooks and contains commands that the user can click on to run them on the virtual nodes in the network emulation
