Extending OpenFlow in Virtual Networks

Software Defined Networking (SDN) is a novel technology that has become a prominent topic in the last years. In any
research is essential to have emulators and simulators in order to test new applications or protocols. In this context, we present the
integration of OpenFlow protocol with Virtual Networks over linuX (VNX) tool, as new alternative for the emulation with SDN.
VNX/OpenFlow approach integrates three kind of tools, an OpenFlow compliant switch (Open vSwitch), Network Operative Systems
(POX, NOX and Beacon) and finally tools to control the performance and the network traffic. For the validation process, we present
two VNX/OpenFlow scenarios to test the correctness of this tool. Finally, the result of this work allows the deployment of virtual
scenarios with OpenFlow protocol.
