Network simulations software

Any suggestions? Do you know Filius? Hi Jan, Thanks for this information. This looks like a Java-based network simulator suitable for teaching basic network concepts. It seems to aim for the same role as the now-defunct Psimulator2, but Filius adds a lot more functionality than Psimulator2. I like Filius and think it would be a great tool for introducing students to traditional IP networking.

Hi Brian, you did a great post and I would like to ask some questions about it. I have thought that I need, first, installing a linux server like ubuntu and on top of that I need to install a network emulator. My first doubt is : am I to install this network emulator as simple software on top of linux server or like a docker or virtual machine?

This network emulator will have to emulate a wan link and connecting two containers which will emulate the streaming servers. Second doubt is : How can I connect these two containers to my network emulator? Or better are these two containers to be installed inside a virtual machine? I mean do I need to nest containers into virtual machines or I simple can connect them to the network emulator?

So to sum up, my ideal scenario would be : a network emulator for emulating a wan link between two video streaming containers and a third machine emulating the client of service. Could you please , help me out to have a clear picture of what software and in which order to install on a unique physical machine? Many thanks in advance. I want to simulate network switch scheduling algorithm for buffered crossbar switches.

Kindly suggest me the simulators for the above work. All the emulators use either Linux bridges or OVS bridges. In your case you will probably have to either implement your switch on a Linux node in your scenario. Or, use a real-time simulator like ns-3 and implement your algorithm in a simulated switch created by you. Hi Thanks for this wonderfull information.

I am a student. I want to work on function placement in NFV. Its aim is to work with them the following concepts:. Great Blog. Network diagram tools are no exceptions. Best option is to use cloud based tools. Such a deep knowledge you have shared with people, In which you have told the deep knowledge of every part which is related to networking. Your post also clears the detail about cloud based tool. Also I am looking for some suggestions.

If possible, guide a way to know whether a particular simulator supports my requirements or not. I am looking for a network simulator that meets the following requirements. Just found this list. For large-scale simulations thousands, hundreds of thousands, … of nodes the above list will not work. There are specialized simulators that simulate specific interfaces, eg. I suppose I could break out each layer logically and draw a box around a switch and router functions to represent the overall TP-Link device but am wondering what other people do?

Hi Experts, can any one suggest me that among all of the list which simulator will be good to practice Palo Alto firewall lab? Hi Friends. How are you. I hope you are fine. Is there any equivalent tool for Greencloud but in NS3? Looks this is an NS2 extension and tcl based.. Also, I feel like the term simulator and emulator are being used incorrectly here. GNS3 is not a simulator. It is an emulation platform. You can run virtual images of numerous devices in it… but you are emulating real network devices.

Brian, this site is a godsend. I have a proposal to write and in looking at potential activities decided that I need a NW modeling and simulation. It could be radios, satellites, drones, wireless , or someone want to test their SDN.

I actually have a question for you. So, out of those, you have run, which do you find to be the best. These simulators and emulators are based on different technologies. So the best for you may be one that is based on a technology or tool you wish to learn like Kubernetes, Docker, or KVM, etc….

That said, the emulators from my list that support almost all vendors, have a strong development roadmap, and have a large community using them are GNS3 and EVE-NG. If you are studying networking, I would suggest you use one of those two. Yes, I have looked at Docker-Topo. It creates a network emulation scenario, described in a YAML file format, based on Docker containers, Linux bridges, and virtual Ethernet devices.

I think Docker-topo is similar in scope to vrnetlab but the author uses a different network plugin for Kubernetes. I cannot recommend a network emulation tool unless I know more about your requirements.

My usual recommendations are to use a tool that is based on the technology you are using every day. Hi Brian, I found this blog by accident but its very informative. I was wondering if you could include a review of free tools for the planning of Optical Networks Software Defined, Mesh, Ring etc. Also there has been a recent surge of interest on utilization Free-Space-Optical communications to route traffic from Ground Station to Satellites, between Satellites etc.

I am very much interested in learning more on how to conduct Optical network planning, simulation and emulation of such networks. If you know of any tools that allow someone to emulate the operation of an optical network, please point me to some links.

I woul very much like to look at them. Heres an interesting link possible new idea Woman delivers baseball smackdown to guy Hits harder than if she used a bat. The included VM Debian is already configured to use it. This tool can be compiled on other Linux Kali,…. It is a useful post about open source network simulators. It would help people who are interested in computer network, network security, and cloud computing.

I need to install one kind of intrusion detection system like snort in the network simulator. Which of those would be good for a distribution network of water? Thanks for your recommendation. It can simulate the network as well as the applications. Both wired and wifi networks are supported. We use flow-level models that are orders of magnitude faster than packet-level models, and we published several scientific publications showing that these models can be made rather accurate with the adequate care.

SimGrid was used as an instrument in over scientific publications, from hundreds of scientists around the world. Text formatting is available via select HTML. Notify me of new posts by email.

It is used for network troubleshooting, interpretation, review, protocol development, and education. Using EVE, you can emulate almost every kind of Network or Security Appliance and build, plan, configure, and test your complex network scenarios in a completely risk-free virtual environment in your machine.

NS is a name for a series of discrete event network simulators, specifically ns-1, ns-2, and ns The Network Simulator — NS-3 is a discrete event simulator targeted at networking research. Network Simulator -NS3 tool provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless local and satellite networks. It is publicly available for research, development, and use. It enables you to develop, test, and train SNMP management applications without buying and managing costly hardware devices.

Your email address will not be published. GNS3 is one of the best simulation tools to build, design, and test your network scenarios and texting is a very risk-free virtual environment. Cisco Packet Tracer is a Network Simulation software which is built for cisco machine. It will help us to create a simple and complex network topology. Cisco Packet Tracer create, plan, configure, and test topologies and imitate the modern computers network.

Putty is a free and open-source Network Simulation Software , serial console, and network file transfer application. Microsoft Visio is a diagramming and vector graphics application build by Microsoft.

Microsoft Visio is an excellent diagramming application that lets you work visually to build all sorts of diagrams and is industry-leading with over 12 million users.

To alleviate this, the software allows for the creation of custom labs, but the file-based distribution of these labs presents its own challenges. Despite the software's maturity, Packet Tracer has issues with lab-breaking bugs that cause simulated network devices to behave in unexpected ways. While utilizing Packet Tracer to lab exam topics for other Cisco certification exams is possible, Packet Tracer should not be considered a primary tool for doing so.

Boson is an IT training organization well-known for their high-quality Cisco certification exam coursework and challenging practice exams. Another key product of Boson's is NetSim, an application that simulates Cisco network routers and switches.

This article evaluates Boson NetSim Licensing Maps to Exams. Boson's licensing model is cumulative just like Cisco certification levels. Each Boson license maps specifically to a Cisco certification exam, and includes the labs for the preceding exams, too. This licensing model is easy to understand, relatively affordable, and provides a large number of built-in labs for each exam.

If you find structure important, this is really convenient. Lab Quality. While the number of labs you receive depends on the price, every Boson lab is high quality and tailored to a Cisco certification exam. Each lab comes with detailed instructions regarding what needs to be configured and verified within the related network topology. Furthermore, most labs ask insightful questions about the output of commands observed in the CLI of the networking device, which helps reinforce understanding about what is being configured and why it needs to be configured.

Just like Packet Tracer, each lab is graded for completion and accuracy within the application. However, where Boson NetSim differentiates itself from Packet Tracer is the ability to track completion of labs from within the application. This feature allows you to view your completed labs, attempted labs, and un-attempted labs at a glance.

It is worth noting here that Cisco's NetAcad courseware also offers labs through Packet Tracer exercises as well as hands-on labs with physical equipment. However, the focus of this article is reviewing the Packet Tracer software itself, not the NetAcad courseware.

Boson's software revolves around purchased lab activities in addition to a sandbox. This is a feature and advantage that NetSim holds over Packet Tracer, which requires your to either get creative or source labs from NetAcad. Lab Accessibility. All purchased Boson labs are easily accessible from within the application, unlike Packet Tracer. There is no need to download labs through individual files and import them into NetSim — all labs are downloaded, completed, and graded from within the application itself.

This lets you focus your time on labbing exam topics rather than downloading files and setting up the lab. Custom Lab Distribution. If you create a network topology that you'd like to share with the world, you can easily upload the topology to the NetSim Community. Conversely, you can browse other people's uploaded topologies and download them from within the application.

As previously mentioned, there is no need to download a separate topology file and import it as is done with Packet Tracer.

Realistic Terminal Features. Copy and paste is very realistic in NetSim. In a real terminal, highlighted text is automatically copied to the system clipboard.

You paste with a right-click. NetSim's terminal mimics this function. This realistic feature sets NetSim apart from Packet Tracer, where this is not supported. By default, terminals are tabbed, so each device's terminal appears within its own tab, unlike Packet Tracer where each terminal gets its own window. If this is not desired, you may place a tab in its own window by right-clicking the tab and selecting the "Float" option. Alternatively, you can drag the tab outside of the terminal window to accomplish the same task.

In fact, the entire interface of NetSim boasts this UI — just about every window can be docked and undocked with ease so that the interface is customized to suit your preferences.

In NetSim, if a network device can be customized through the addition of modules which it calls "Addons" , the software explicitly asks what modules you would like to insert in the device when the device is added to a network topology.

Additionally, NetSim calls out the type of interfaces that each module adds. For example, if you want to add an HWIC-2T network module to a device, NetSim explicitly tells you that the addition grants two additional serial interfaces that the device can use.

Finally, once a device has been customized and added to the network topology, a device with the same physical configuration is saved in the "Recent Devices" window. This modified device can be easily added to the topology by dragging it from the "Recent Devices" window into the network topology. Less clicking than Packet Tracer. In Packet Tracer, you must place a device in your network topology, manually power off the device by clicking on the power switch , drag the desired network module to the desired slot, then manually power on the device by clicking on the power switch.

Furthermore, this process needs to be repeated for each device that needs its physical configuration modified. If you need to test a topology in Packet Tracer with eight routers using serial interfaces, modifying each device results in a lot of clicking.

Lack of Topology Information. The network topology window shows a limited amount of information, especially while a simulated topology is running. For example, you can't see the link state of each connection between network devices, nor do you have any indication that the device is actively transmitting data.

The primary source of feedback for this type of information is the device itself. While this could help prepare you for a role as a remote network administrator where physical access to devices is not possible, the additional feedback in simulation would be particularly helpful for visual learners. Lack of Topology Customization. Unlike most other network simulators and emulators, NetSim does not have a way to add colorized shapes to a network topology.

Aside from network devices and connections, you can only add text-based notes and labels to the topology. This is a fairly minor point, but is important when rehearsing some exam topics, such as multiarea OSPF, where colored shapes illustrating the different areas comes in very useful.

Cannot Modify Active Topology. Once a network topology is running, you can't modify it until you stop the topology, which shuts down the simulated network devices. If you need to add a new network device or a new connection to your network topology, you must stop the entire topology, modify it as needed, then start the topology once more.

This is a minor point, as the topology itself starts and stops very quickly, but the less time you spend managing simulator, the better! No Simulation Mode. There is no way to place NetSim's network topologies into a "simulation mode" like one can with Packet Tracer. There is no way to view the contents of individual packets as they traverse the network in NetSim.

All network devices are simulated in real-time. As a result, you can't visualize the path of a packet throughout your simulated network the same way that you can in Packet Tracer. No Cross-Platform Compatibility. It is not supported on macOS or any Linux distribution.

Boson NetSim's strongest feature is the built-in labs that directly map to the exam topics of specific Cisco certification exams. For existing patrons of Boson's courseware and practice exams, these labs are an excellent practical aid for reinforcing networking concepts. The fact that labs whether they were built by Boson or built by the community can be accessed directly through the NetSim application simplifies the labbing experience and lets you focus on learning instead of prerequisite tasks.

The software's weakness is in the creation, manipulation, and interaction of network topologies in the sandbox environment. It is more difficult to create aesthetically-pleasing network topologies in NetSim compared to other network simulators and emulators.
