In a virtualized SDN (vSDN), a network hypervisor plays a key role in translating physical network resources into virtual network resources. However, this translation in vSDN incurs(More)
In this paper, we propose AggFlow, a new address virtualization scheme for high scalability and resource efficiency. AggFlow is intended to provide complete address virtualization while incurring low overhead for physical switches and the control channel. To reduce overhead of address virtualization, we propose mapping-less address virtualization. We(More)
