GNS3

Developed in 2008, Graphical Network Simulator 3, or GNS3, is a powerful, open-source network simulation software. Developed for designing network topologies in virtual or real-world environments, GNS3 supports the development of network test scenarios and real-world applications.

Frequently used by network professionals such as IT professionals, students, and network engineers, GNS3 is an emulator with advanced features and a user-friendly interface. With over 19 million downloads, the software is used by major companies such as Google, NASA, Pfizer, Intel, HSBC, Huawei, Target, and Walmart. The main menu bars and shortcuts in the software, which runs on Mac, Windows, and Linux operating systems, allow you to quickly access features.

With GNS3, you can design, test, and conduct research on networks of various sizes in a risk-free virtual environment, without the need for hardware. With the software, which offers testing capabilities on more than 20 different hardware types, you can test your designs, identify and troubleshoot errors. GNS3, which accelerates the production process with dynamic network maps, allows you to connect your existing hardware to a real network, enabling faster execution of your operations.

GNS3, a simple, drag-and-drop software that supports creating the virtual work environments required by students preparing for network certification exams like Cisco and Juniper, significantly simplifies adding devices, network connections, and configurations. By visualizing application and network structures, you can better evaluate your designs and tests.
