Network virtualization is a concept where physical resources are used to create virtual resources that are combined to form virtual networks. As one of the key enablers of the future Internet, network virtualization solves a number of issues associated with today's networks. Concepts of network virtualization that are not restricted to virtualization technology, termed as overall concepts that include roles of parties and deployment aspects are currently being defined in different research activities. An area that lack attention is the evaluation of performance in prototypes that consider these overall concepts of network virtualization. The work presented here discusses and presents the performance in a network virtualization prototype that considers these overall concepts.
