HyperFlex: Demonstrating control-plane isolation for virtual software-defined networks

HyperFlex: Demonstrating control-plane isolation for virtual software-defined networks We present a demonstration of HyperFlex [1], a Software-Defined Networking (SDN) virtualization architecture with flexible hypervisor function allocation guaranteeing control-plane virtualization.Network Virtualization (NV) is expected to overcome the ossification of today’s communicationnetworks. SDN is seen as an enabler for programmable network control. In order to fully virtualizesoftware-defined networks, not only the virtualization of the data-plane, but also the virtualization of the control-plane has to be considered. HyperFlex is a virtualization hypervisor that ensures isolated control-plane slices for virtual SDN networks. Control-plane isolation also protects the hypervisor resources from exhaustion. Furthermore, virtualization hypervisors have to be scalable and flexible in order to provide the best possible performance for the virtual software-defined networks. They should be able to adapt to the current state of the network and the divergent demands of virtual SDN networks. HyperFlex distributes the hypervisor functions flexibly and dynamically in order to adapt to the currentnetwork state.
