Abstract

Cloud services that virtualize existing IT infrastructures in data centers are widely used by governments, universities, and companies. Multi-tenancy is an indispensable feature for data centers to provide a large number of isolated networks to different organizations. OpenFlow is a core technology of software defined networking (SDN) and is useful for centrally managing and controlling these networks; however, SDN is used only at the management level. It is desirable to make the flexible features of SDN/OpenFlow available to users’virtual networks. FlowVisor provides virtualized multi-tenant OpenFlow networks by coordinating multiple controllers, but it is unable to prevent conficts among the control rules of individual virtual networks. Administrators of each tenant thus need to design the specifications of each virtual network carefully. In this paper, we propose a verification based virtualization system for multiple tenants’Openflow networks. It enables users of virtual network, that are administrators of the tenant’s network, to design their own virtual networks without considering conficts with other tenants. Our system provides a practical scheme to abstract and create virtual network topology which is the target of control for the tenant’s Openflow controller.
