Network virtualization : A way forward for accommodating multiple, heterogeneous architectures in a single infrastructure

Future Internet researches revolve around the notion “Architecture”. Architecture can be defined as the set of principles and basic mechanisms that guide network engineering. Historically, informal architectural ideas guided design of the Internet protocols, but the architecture was formalized later. The today's Internet architecture is under serious reconsideration and people started thinking about alternatives. It is necessary to support a variety of the new different architectures to accommodate the heterogeneity of Future Internet. In the paper, we discuss new challenges on network virtualization and discuss a new way forward for accommodating the multiple, heterogeneous architectures in a single infrastructure.
