GNS3 is an open source software which  visualizes, plans, tests and troubleshoost network environments across any vendor platform at scale - without the need to directly interact with the network hardware.

GNS3

Network simulation software emulate the behavior of a modeled network for a variety of testing purposes in a repeatable and controllable environment, using simulation to understand how various changes will influence performance during some anticipated future configuration or application deployment.

Network Simulation Software

I have been using GNS3 for more than 4 years, and it is a really useful program. With GNS3, we can create practical labs with all of their contents of routers, switches, wired, and wireless communication devices, all without incurring any costs, which is great. This product is special because it solved a problem at work, namely, linking physical devices to virtual devices within the program.

The possibility of applying integrated labs that simulate reality by more than 90%.
It enables the addition of different network devices from all vendors with the possibility of integration between them.

In my opinion, the program consumes a lot of device resources, especially when using the iOS version.
The program does not contain network devices, so you need to search for the network devices that you need and add them manually.
