N2 - Software defined networking (SDN) is a recent architectural framework for networking, which aims at decoupling the network control plane from the physical topology and at having the forwarding element controlled through a uniform vendor-agnostic interface. A well-known implementation of SDN is OpenFlow. The core idea of OpenFlow is to provide direct programming of a router or switch to monitor and modify the way in which the individual packets are handled by the device. We describe our implemented fast failure recovery mechanisms (Restoration and Protection) in OpenFlow, capable of recovering from a link failure using an alternative path. In the demonstration, a video clip is streamed from a server to a remote client, which is connected by a network with an emulated German Backbone Network topology. We show switching of the video stream from the faulty path to the fault-free alternative path (restored or protected path) upon failure.
