An Architecture for Concurrent Future Networks
One of the key interests in Future Internet research is network virtualization. It allows to operate multiple networks in parallel, each possibly having different applications, requirements, protocols, and even users. For the 4WARD Project1 network virtualization is one of the core concepts to let 1000 networks bloom. With such highly specialized virtual networks, users do not just use a single network but will use several virtual networks in parallel. A user could, for example, have one virtual network optimized for voice communication with family members, while another virtualized network is used for communicating sensitive information with business partners. A third general purpose network, like today's Internet, could be used for exchanging electronic mail.
