I need to know which one is easiest on config, run and test. If you need to use a discreet-event simulator like NS-2 or NS-3, then I do not have an opinion because I have not used those tools very much. NS-3 is the newer version so maybe you should use the tool that is currently supported (NS-3).
Mental imagery not only allows us to predict the imminent or distant future, but also to consider many possible futures—or even many possible worlds. For example, when deciding the best way to drive home from a friend’s house, you might imagine several alternative routes, and compare the likely traffic patterns, the number of stoplights and so on. This same mental machinery allows us to revisit events that have already occurred (e.g. the images of a murder scene formed by someone who witnessed the crime). get better confiability tests, especially if you need to do regression testing, performance testing, interoperability testing, sanity testing or smoke testing.
Hi Brian, I am student at DeMonfort University which is based in the UK and I am studying Computer Security . For my final year, I am required to do a Research Development Project (which is based on Penetration-Testing) for my dissertation. For my project, I am trying to find 3 or more types of CCNA/Cisco based router simulators, to compare and identify the vulnerabilities, as it will allow me to find ways to exploit them. I cannot recommend a specific emulator because I do not know all your requirements. I suggest you consider what type of virtualization best meets your requirements and use that as a basis for choosing the emulator.

- A simulator is designed to create an environment that contains all of the software variables and configurations that will exist in an application’s actual production environment.
- However, simulators do not attempt to emulate the actual hardware that will host the application in production.
- Emulators and simulators both make it possible to run software tests inside flexible, software-defined environments.
- Because simulators create only software environments, they can be implemented using high-level programming languages.
- In this way, they allow you to run tests more quickly and easily than you could if you had to set up a real hardware device.
- But the fact remains that simulators and emulators are different beasts.

So, out of those, you have run, which do you find to be the best. I am looking to be able to recreate routing/switching environments up to Enterprise networking levels.
I am studying to take a job, and need to refresh myself on primarily switching, but I am also rusty with my routing protocols, and I will be working with OSPF and BGP. I will also be working with Brocade switches in the new job, and am hopeful that one of these also simulates/emulates their technology. This class of simulators is searchable via “SNMP simulator”, “MQTT Simulator”, etc. For IoT, try Mininet-WiFi, which is a fork of Mininet with wireless emulation features.
That said, to run different routing protocols more easily, I suggest using an emulator like CORE. It may not produce perfectly repeatable results but it will allow you to set up test much more quickly. I don’t know enough about the software you want to emulate to make a strong recommendation. If you are familiar with a tool\tools combination that can supply all\some of the above functionality, I’ll realy appreciate your help.
I already own the Cisco equipment and IOS, so if I can load them all and drop in my existing configs, I’m off and testing. New York University recently released an open source end-to-end network simulator for 5G mmWave sonic 3 and knuckles rom rom download cellular networks based on the NS-3 simulator. Hello guys, I am working on a project and I have a doubt, actually I am looking for an open source software tool which is appropriate to simulate SDN/NFV Environment. I want to develop a new File Transfer Protocol for Local Area networks and i do not know which simulator is more proper for that.
CORE has the ability to connect to a Docker container but does not implement nodes using Docker. No, I am not aware of an open-source network emulator or Simulator for optical networks. I’m after a network simulation and modelling tools capable of producing graph or table results for comparison purposes. I have a current location and I want to practice if it goes down.
They can be broken, after a while, you have to change them for the newest devices. For example, you can use the mobile view when you press f12 on chrome, then you toggle the device toolbar and change from responsive to device design. I see in the comments that you haven’t run each and every simulator/emulator posted in this list.
