This is a list of open source network simulators and network emulators that run on Linux or BSD. Please post a comment on this page to let me know about any other open source network simulation tools I did not include in this list. Cloonix. The Cloonix network simulator provides a relatively easy to use graphical user interface. Cloonix uses QEMUKVM to create virtual machines. Cloonix provides a wide variety of pre built filesystems that can be used as virtual machines and provides simple instructions for creating other virtual machine root filesystems. Cloonix has an active development team, who update the tool every two or three months and who are very responsive to user input. Please click here to see my posts about Cloonix.

Cisco Switch Ios For Gns3' title='Cisco Switch Ios For Gns3' />COREThe Common Open Research Emulator CORE provides a GUI interface and uses the Network Namespaces functionality in Linux Containers LXC as a virtualization technology. This allows CORE to start up a large number of virtual machines quickly. CORE supports the simulation of fixed and mobile networks. CORE will run on Linux and on Free. BSD. CORE is a fork of the IMUNES network simulator, and it adds some new functionality compared to IMUNES. Please click here to see my posts about the CORE Network Emulator. CORE web site http cs. Cisco 3750 at Routerswitch, and cisco price at great. Cisco Networking with GNS3 by. GNS3. GNS3 is a graphical network simulator focused mostly on supporting Cisco and Juniper software. GNS3 has a large user base, made up mostly of people studying for Cisco exams, and there is a lot of information freely available on the web about using GNS3 to simulate Cisco equipment. GNS3 can also be used to simulate a network composed exclusively of Virtual. Box andor Qemu virtual machines running open source software. GNS3 provides a variety of prepared open source virtual appliances, and users can create their own. Please click here to see my posts about GNS3. GNS3 web site http www. IMUNESA team of researchers at the University of Zagreb developed the Integrated Multi protocol Network EmulatorSimulator IMUNES for use as a network research tool. IMUNES runs on both the Free. BSD and Linux operating systems. It uses the kernel level network stack virtualization technology provided by Free. BSD. It uses Docker containers and Open v. Switch on Linux. IMUNES supports a graphical user interface. It works well and offers good performance, even when running IMUNES in a Virtual. Box virtual machine. Please click here to see my posts about IMUNES. IMUNES web site http www. Mininet. Mininet is designed to support research in Software Defined Networking technologies. It uses Linux network namespaces as its virtualization technology to create virtual nodes. The web site indicates that the tool can support thousands of virtual nodes on a single operating system. Mininet is most useful to researchers who are building SDN controllers and need a tool to verify the behavior and performance of SDN controllers. Knowledge of the Python scripting language is very useful when using Mininet. The Mininet project provides excellent documentation and, judging from the activity on the Mininet mailing list, the project is actively used by a large community of researchers. Some researchers have created forks of Mininet that focus on specific technologies. I list projects based on Mininet below Please click here to see my posts about Mininet. Mininet web site http www. Netkit. Netkit is a command line based simulation tool that uses user mode Linux to create the virtual machines. A full Linux OS can run on each machine. Cisco 3750 Switch Ios For Gns3 Workbench DownloadIt has good documentation and the projects web site has a long list of interesting lab scenarios to practice, with documentation for each scenario. It also appears to be actively supported by a small community and was last updated in 2. Please click here to see my posts about Netkit. Netkit web site http wiki. NS 3. NS 3 is a discrete event open source network simulator for Internet systems, used primarily for research and educational use. NS 3 is a complex tool that runs simulations described by code created by users, so you may need programming skills to use it. NS 3 can run real software on simulated nodes using its Direct Code Execution feature. This allows researchers to test real software like Quagga or web servers in a discreet event network simulation to produce repeatable experiments. NS 3 is meant to replace NS 2, a previous version of the network simulator. NS 2 is no longer actively maintained but is still used by some researchers. I have not used NS 3, yet.

Stack installation on a single machine, such as a laptop or a virtual machine. The best known tool is Dev. Stack but most vendors Open. Stack deployment tools offer a way to install an all in one Open. Stack system. In a way, any of these all in one systems can serve as an Open. Stack simulator for students and researchers interested in experimenting with cloud systems. Links to single node installers Dev. Stack single node install. Ubuntu Open. Stack Autopilot single node install. Red Hat RDO single node install. Openstack on Ansible single node install. Shadow. Shadow is an open source network simulatoremulator hybrid that runs real applications like Tor and Bitcoin over a simulated Internet topology on a single Linux computer, and also on a pre configured AMI instance on Amazon EC2. Users run a simulation by creating an XML file to describe the network topology and plugins to link their application code to nodes in the simulation. They see the results of their experiments in log files generated by Shadow. Shadow operates as a discrete event simulator so experimental results are repeatable. Shadow can also run real software on its virtual nodes, using plugins created by the user. This combination of features discreet event simulation coupled with real software emulation makes Shadow a unique tool. I have not yet used Shadow. It seems to be useful to developers who want to test the performance of distributed or peer to peer applications like TOR and Bitcoin. Shadow network simulator web site https shadow. UNet. LabEVE NGUNet. Lab and EVE NG are network emulators that support virtualized commercial router images such as Cisco and NOKIA and open source routers. They use Dynamips and IOS on Linux to support Cisco router and switch images, and KVMQEMU to support all other devices. Each is available as a virtual machine image and may also be installed on a dedicated server running Ubuntu Linux. EVE NG is the next generation of UNetlab. It is currently part of a crowd funding campaign to raise funds to support development. UNet. Lab is the stable version and EVE. NG is available as an alpha version. Both UNet. Lab and EVE NG are open source and post source code on Git. Hub for UNet. Lab and on Git. Lab for EVE NG. UNet. La. BEVE NG web site http www. VNX and VNUMLVNX supports two different virtualization techniques and uses an XML style scripting language to define the virtual network. It also supports chaining multiple physical workstations together to support distributed virtual labs that operate across multiple physical workstations.
