GNS3 is an easy to use, small network simulation utility that can be used to create complex network topologies.
In order to make complete simulations possible, GNS3 is strongly linked with:
· Dynamips, an IOS emulator which allows users to run IOS binary images from Cisco Systems.
· Dynagen, a text-based front-end for Dynamips.
GNS3 is an open source product that may be used on multiple platforms, including Mac OS X, Windows, and Linux.
NOTE: Users must provide their own Cisco IOS to use GNS3.
Here are some key features of "GNS3":
· Designing high quality complex network topologies.
· Emulating Cisco routers.
· Simulating simple Ethernet, ATM and Frame Relay switches.
· Load-balancing between multiple hypervisors.
· Load and save in Dynagen's INI-like format.
· Image export (JPEG, PNG, BMP and XPM).
· Python 2.5.1 or later
· Apple Devs Tools
