We demonstrate IP fast reroute using a recently proposed method called Relaxed Multiple Routing Configurations. While IP fast reroute has been researched intensively in recent years, no practical implementations are known to exist prior to the system we demonstrate. The goal of the demonstrator is to show the effect of network failures on real-time applications with and without IP fast reroute mechanisms deployed. For best illustration we use video transmission showing that IP fast reroute can elliminate frame freezing upon cable cut.
