Graph abstraction based Virtual Network management framework for SDN

Currently, Software Defined Networking (SDN) paradigm has attracted a significant interest from industry and academia as a future network architecture. The programmable control plane enables flexible and rapid modifications of network behavior. With OpenFlow, one of the promising SDN protocols, we can provide several advantages to develop advanced network virtualization technologies. In this paper, we propose a graph abstraction based virtual network management framework that covers from tenant requirement specification to virtual network embedding on physical resources. The fundamental idea is to automatically create and manage virtual networks on the top of SDN technologies from high level tenant requirements. We expect that the proposed framework can overcome the limitation of overlay based network virtualization technologies, and leverage the deployment of SDN technologies.
