I. brief introduction:

GNS3 is a network virtual software with a graphical interface that can run on multiple platforms (including Windows, Linux, and Mac OS, etc.). Cisco network equipment administrators or people who want to pass the Cisco certification exam such as CCNA,CCNP,CCIE can use it to complete the relevant experimental simulation operations. At the same time, it can also be used to virtually experience the Cisco Internet operating system IOS or to verify the relevant configuration that will be deployed on a real router. To put it simply, it is a graphical front end of Dynamips, which is easier to use and more operable than using virtual software such as Dynamips directly.

Second, advantages:

Lies in providing win32 applications with the ability to access the underlying network. Excellent network topology design; simulation of Cisco routing devices and PIX firewall; simple simulation of Ethernet, ATM and frame Relay switches; ability to load and save to Dynamips configuration format, that is to say, good compatibility for virtual software using dynamips kernel to support the export of some file formats (JPEG, PNG, BMP and XPM).
