The Caml Hump: Marionnet

Marionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked GNU/Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switchs, cables, and more. Support is also provided for integrating the virtual network with the physical host network. As Marionnet is meant to be used also by inexperienced people, it features a very intuitive graphical user interface.
