Please click here to see my posts about the CORE Network Emulator.Д®VE-NG is a network emulator that supports virtualized commercial router images (such as Cisco and NOKIA) and open-source routers. CORE is a fork of the IMUNES network simulator, and it adds some new functionality compared to IMUNES. CORE supports the simulation of fixed and mobile networks.Д¬ORE will run on Linux and on FreeBSD. This allows CORE to start up a large number of virtual machines quickly. The Common Open Research Emulator (CORE) provides a GUI interface and uses the Network Namespaces functionality in Linux Containers (LXC) as a virtualization technology. Please click here to see my posts about Containerlab. Containerlab also supports VM-based network devices so users may run commercial router disk images in network emulation scenarios.

More interestingly, Containerlab supports any open-source network operating system that is published as a container image, such as the Free Range Routing (FRR) router. It starts the containers, builds virtual wiring between them to create lab topologies, and manages each labвЂ™s lifecycle.Д¬ontainerlab supports containerized router images available from the major networking vendors. It provides a command-line-interface for orchestrating and managing container-based networking labs. Please click here to see my posts about Cloonix.Д¬ontainerlab is an open-source network emulator that quickly builds network test environments in a devops-style workflow.

Cloonix has an active development team, who update the tool every two or three months and who are very responsive to user input. 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 uses QEMU/KVM to create virtual machines.

The Cloonix network simulator provides a relatively easy-to-use graphical user interface. Please click here to see my posts about Antidote. Its user interface operates in a web browser, including the terminals that students use to run commands on emulated network devices and servers 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.ДЄntidote is a network emulator combined with a presentation framework designed to create and deliver networking technology training. This is a list of open-source network simulators and network emulators that run on Linux or BSD. Older news is archived on the Network Simulator News page. Plots and graphs can be generated and reports can be exported to Excel for further analysis.FRRouting recently added a set of YANG models with a GRPC support, which should enable researchers to experiment with modern network automation tools on an open-source router. What's more, NetSim enables you to analyze the performance of your network architecture at multiple levels, taking into account throughput, delay, data loss and errors. The integrated packet animator allows you to view a graphical representation of how data packets are transmitted through both wired and wireless networks. NetSim reveals the arrival time, queuing time, payload and possible error causes for all packets that travel across the nodes and generates reports concerning all events, logging the event time stamp and type. Simulations can be run from within the GUI or using the command console.

Additionally, NetSim enables you to change the properties of each device and view the impact on the entire network layout. Various protocols are supported.ДЇurthermore, NetSim supports XMl configuration files, in case you don't want to create the network yourself.Дrag and drop actions are enough to place a device or create a link between multiple points in your network. With NetSim one can easily create network scenarios with different configurations comprising all kinds of devices, from simple workstations to servers and sensors, ATM switches or routers. NetSim can create anything from simple home networks to large, complex ones, performing efficiency and reliability verifications to discover connectivity problems. It can assess network reliability, displaying information regarding the system behavior and problems that might occur. NetSim is a powerful and comprehensive network simulation utility that can assist you in designing an efficient network architecture.
