ABOUT THIS SOFTWARE
GNS3 (Graphical Network Simulator -3) is an open source simulation platform commonly used in network technology training, such as Cisco certifications. It allows you to integrate real router and switch images (such as Cisco IOS) into a virtual environment and connect them to virtual and physical networks. With this, students can build and configure realistic network environments including routers, switches, firewalls and more, without expensive equipment.
