Resumen
The separation of control and forwarding planes in software-defined networking (SDN) networks is a key issue of the SDN technology. This feature and the existence of the SDN controller allow the developing of dynamic, adaptable and manageable networks, networks that require adequate services, and applications. However, the separation of these planes prevents the use of existing powerful tools that were coded considering traditional networks. In this paper, we make use of the potential of network virtualization (NV) technologies to propose the use of a virtualized infrastructure that makes possible the incorporation of these existing services and/or applications to an SDN network, without the need for programming additional and complex software modules in the SDN controller. Thus, in this paper, NV is not employed to develop a network managed by SDN but to broaden and give support to the SDN control layer. As an example, we describe the incorporation of nmap (a versatile and powerful tool ...
