Demonstrating a distributed and version-agnostic OpenFlow slicing mechanism

Several virtualization frameworks have been proposed in the last few years for Software Defined Networks (SDN), however, they are either based on proxy-based solutions that raises scalability and robustness issues (FlowVisor), or they leverage on a simplified view of the data-path (generally based on Open vSwitch instances) that have little chances to be adopted in production network settings. In our demonstration we present preliminary results obtained by deploying and using a novel OpenFlow-based network virtualization mechanism. The mechanism is based on a recently proposed distributed virtualization architecture that is able to run on multi-version OpenFlow scenarios.
