Features of GNS3

The main purpose and use of GNS3

GNS3 is a tool mainly deployed by network developers and IT professionals doing similar tasks. The main benefit associated with this system is that it provides a graphical representation of the nodes in a system.

This top-down view clearly illustrates real-time operations, and so any changes can be made in a relatively short period of time. While boasting of the ability to perform complex operations, the layout of the app itself is quite simple.

A menu is displayed on the left side of the page. This highlights any existing routers and switches.

Additional Applications

GNS3 also uses an emulation mode; useful when testing the availability of 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 ZIP format for easy installation.

Advantages

2. Any source code can be viewed and changed if required.
