[Abstract] In this paper, we describe two ways of introducing software defined network (SDN) technology into the mobile core network: 1) further separation of control functions from the forwarding gateway and 2) user and service oriented smart packet routing. We also discuss the near-term possibility of using SDN in a data center as well as between data centers. Finally, we discuss the use of SDN for network virtualization.
