Network virtualization is one of the foundations for Future Internet architectures, able to catalyze technologies for the solution of classical problems in the IP layer. The work here gives a step forward in that direction, evaluating the performance of different virtual network tools under the perspective of a virtualized IP routing control plane. Two lightweight container-based virtualization systems, OpenVZ and LXC, were selected based on specific criteria and evaluated in the context of virtual routers. Obtained results allow for a comparative analysis about the convergence of the routing protocol and give insights about the adoption of these tools on a routing as a service platform.
