GNS3 is a software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches.It also employs an emulation mode; useful when bench testing a new system or when troubleshooting an existing network. Of course, the programmer also has the ability to display and modify any source code (while observing the output). All files are available in a ZIP format for easy installation.
GNS3 is a software that simulate complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches. It can also be used to experiment features or to check configurations that need to be deployed later on real devices.
Real-time network simulation for pre-deployment testing without the need for network hardware
Run the OS that emulates the real behavior of network hardware.Test 20+ different network vendors in a risk-free virtual environment
Quickly run and test multiple hardware vendors without the need for hardware.

Create dynamic network maps for troubleshooting and proof of concept (POC) testing
Test your networks before you build them to reduce the time it takes to get a production network up and running.

Connect GNS3 to any real network
Leverage your existing hardware and expand your current lab by connecting you’re the app topologies directly to it.

Customized topologies and labs within GNS3 for network certification training
This app is the best study tool for aspiring network professionals seeking their certifications, without the need for a home lab.

Purpose and Uses

GNS3 is a tool that is primarily deployed by network developers and similar IT professionals. The primary benefit associated with this system is that it provides a graphical representation of the nodes within a system. This top-down perspective clearly illustrates real-time operations and therefore, any changes can be made within a relatively short amount of time.
