open-source network simulation tools that run on Linux or BSD systems
The UNetLab and EVE-NG network emulators can become powerful tools for emulating open-source networks. However, When first installed, they support Linux images only in a limited way. Fortunately, it is easy to extend UNetLab and EVE-NG to support powerful, general-purpose Linux router and server images. In their default configuration, UNetLab and EVE-NG support Linux nodes […]
EVE-NG and UNetLab are graphical network emulators that support both commercial and open-source router images. UNetLab is the current, stable version of the network emulator and EVE-NG is an updated version of the same tool, available as an alpha release. The UNetLab/EVE-NG network emulator runs in a virtual machine so it can be set up
OFNet is a new software-defined network (SDN) emulator that offers functionality similar to the Mininet network emulator and adds some useful tools for generating traffic and monitoring OpenFlow messages and evaluating SDN controller performance. OFNet is an open-source project that is distributed as a virtual machine (VM) image. The OFNet source code is available in
Roland Kuebert forked the psimulator2 network simulator project from the original, seemingly discontinued source and made the new version available at https://github.com/rkuebert/psimulator. Roland posted this announcement in the comments under my psimulator2 blog post. So that his announcement receives a bit more visibility, I am re-posting his comment verbatim below: Hi all, Just a heads
VirtualBox is an open-source virtual machine manager and hypervisor that may also be used as a network emulator. In addition to creating and managing individual virtual machines, VirtualBox can connect virtual machines together to emulate a network of computers and network appliances such as routers or servers. VirtualBox works on the major computing platforms: Windows,
This post lists the commands required on each node to build a network of three Ubuntu Linux routers. Each router is connected to the other two routers and is running quagga. Each router is also connected to a PC running Ubuntu Linux. I use this network configuration to evaluate network emulators and open-source networking software
dCore Linux is a minimal Linux system based on the Tiny Core Linux system. Like Tiny Core Linux, dCore loads its file system entirely into RAM, which should provide good performance in large network emulation scenarios running on a single host computer. dCore Linux allows users to install additional software from the Debian or Ubuntu
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
To learn more about OpenStack cloud management software, a student or researcher may install OpenStack on a single machine, such as a laptop computer or a virtual machine, and emulate a small datacenter using virtual machines or containers. Researchers and students may choose from multiple projects that will set up OpenStack on a single machine.
