Whitepaper: Advanced Network Simulation Under User-Mode Linux

by Gesellschaft für Informatik e.V.Jan 01, 2008

In this paper, the author describes that debugging of data communications software in an active networking environment can be a tricky and quite tiresome affair, often so because intermittent disturbances occurring in productive systems cannot be reproduced reliably and consistently or cannot be traced thoroughly enough. Thus for any Linux-based networking appliances like routers, firewalls, intrusion detection systems, VPNs, VoIP gear, etc., the User-Mode-Linux (UML) framework presented in this paper might be the optimum solution for running and testing these systems in a virtual networking environment under near real-time conditions.
