What is GNS3?

GNS3 (Graphical Network Simulator 3) is an open-source software that imitates the way real networks perform by simulating complex networks, all without the help of routers or switches. It is recommended for use by network engineers and administrators. It is also for people who are studying for certifications such as Cisco CCNA, the CCNP, the Juniper JNICA, and the JNCIE. The program connects the virtual network of the user to the real world. It runs on PC hardware and can be used on different operating systems including Windows, Linux, and MacOS X.

GNS3 also supports open source networking. It is used to experiment on features or check configurations that need to be arranged on real devices. To use GNS3, the user needs to have his own copy of a network operating system.
