GNS3: design complex network topologies

GNS3 is a free program that enables you to create complex network topologies and deploy simulations on them. The application is a graphical network simulator that comes packed with all the features you need to design complex network topologies and launch simulations on them.

Features:

- Enables you to design complex network topologies.
- Cisco routers simulation capabilities.
- Allows you to simulate simple Ethernet, ATM and Frame Relay switches.
- Load-balancing function between multiple hypervisors.
- Allows you to load and save in Dynagen’s INI-like format.
- The following image formats can be exported: JPEG, BMP, PNG and XPM.

Requirements:

- Dynamips 0.2.8 RC1
- WinPCAP 4.0.1
