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.

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.
Mininet-WiFi: SDN emulator supports WiFi networks
Mininet-WiFi is a fork of the Mininet SDN network emulator. The Mininet-WiFi developers extended the functionality of Mininet by adding virtualized WiFi stations and access points based on the standard Linux wireless drivers and the 80211_hwsim wireless simulation driver. They also added classes to support the addition of these wireless devices in a Mininet network
Using the OpenDaylight SDN Controller with the Mininet Network Emulator
OpenDaylight (ODL) is a popular open-source SDN controller framework. To learn more about OpenDaylight, it is helpful to use it to manage an emulated network of virtual switches and virtual hosts. Most people use the Mininet network emulator to create a virtual SDN network for OpenDaylight to control. In this post, I will show how
Using POX components to create a software defined networking application
When network engineers are learning the concepts of software defined networking and SDN controllers, they may want to experiment with SDN network scenarios before learning to write programs to be used by the SDN controllers. POX is a simple-to-use SDN controller that is bundled with the Mininet SDN network emulator and is used in education
How to map OpenFlow switches to TCP ports in Mininet SDN simulations
When testing SDN functions in the Mininet network emulator and viewing captured OpenFlow messages in a packet analyzer such as Wireshark, it is difficult to identify which SDN switch is the source or destination of each captured message. The only reliable way to identify which SDN switch sent or received an OpenFlow message is to
Visualizing software defined network topologies using POX and Gephi
When a researcher uses the Mininet network simulator to create a network of hosts and switches connected to an SDN controller, he or she may wish to be able to see what the simulated network topology looks like. The POX SDN controller includes a component that will send network topology data to the Gephi data
Using the POX SDN controller
In this tutorial, we demonstrate basic software-defined networking (SDN) concepts using the POX SDN controller, POX components, and the Mininet network simulator. We will show how to use the POX SDN controller to update flow tables on the SDN switches in a simulated network so every host on the network can forward packets to another
How to use MiniEdit, Mininet’s graphical user interface
The Mininet network simulator includes MiniEdit, a simple GUI editor for Mininet. MiniEdit is an experimental tool created to demonstrate how Mininet can be extended. To show how to use MiniEdit to create and run network simulations, we will work through a tutorial that demonstrates how to use MiniEdit to build a network, configure network
Install Mininet on an Amazon EC2 server
To install the Mininet SDN network simulator on a remote server running on Amazon’s EC2 cloud, follow the procedure shown below. After installing it, I did some basic tests and it seems that Mininet works well on the Amazon EC2 server.
How to build Mininet documentation
After installing the Mininet software-defined network simulator on a virtual machine, you may want to build the documentation. Documentation is available on the Mininet web site but, if you installed a beta version of a new development release or installed an old version, you may want to use the documentation specific for the version you
How to install the Mininet SDN Network Simulator
Most people who use the Mininet network simulator will download and set up the Mininet virtual machine image. However, there are times when we may want to use a different version of Mininet than the one already installed in the Mininet VM. For example, we may want to use the newest features of Mininet currently
