    145145==== Dynamic Virtual Router Failure Recovery ====
    146146
    147 In this demo, I will show a dynamic virtual router failure recovery by using a standby virtual router in the virtual network environment using GENI testbed. I will show the heuristic algorithm that select an optimal standby virtual router from a few preserved virtual standby virtual routers, by considering two criteria (i.e. geographical distance and VM load on the physical host).
     147Network virtualization allows flexibility to configure virtual networks in a dynamic manner. In such a setting, to provide resilient services to virtual networks, we consider the situation where the substrate network provider wants to have standby virtual routers ready to serve the virtual networks in the event of a failure. Such a failure can affect one or more virtual routers in multiple virtual networks. The goal of our work is to make the optimal selection of standby virtual routers so that virtual networks can be dynamically reconfigured back to their original topologies after a failure. We present an optimization formulation and a preliminary implementation on GENI testbed by applying the idea behind the model. The selection metrics considered are geographical location and the VM load on the standby virtual router's host machine.
