Disclosed is a network hypervisor apparatus for providing a software defined networking (SDN)-based virtual network, the network hypervisor apparatus including a data collector configured to collect control traffic data and network topology information for each virtual switch; a control traffic predictor configured to predict future control traffic based on the control traffic data and the network topology information; and a translator configured to translate a control message corresponding to a virtual switch based on a prediction result.

Control channel isolation with time-series control traffic prediction in programmable network virtualization

Disclosed is a computing apparatus implemented with a network hypervisor implementing software defined network (SDN)-based network virtualization. The computing apparatus include a statistics virtualization module configured to provide individual statistics to each of created virtual networks, a transmission disaggregation module configured to include a physical statistics cache that performs periodic monitoring of a plurality of physical switches and store statistics of the physical switches collected, and a physical statistics aggregation module configured to respond with statistics of the plurality of physical switches when a single monitoring request.

Network monitoring apparatus and method thereof in programmable network virtualization

A flow rule virtualization method is disclosed. The flow rule virtualization method may include: (a) generating a virtualization type table, (b) selecting a virtualization type, which represents the degree of mapping between a virtual flow rule and a physical flow rule executed on a physical network, for a virtual flow rule generated from a tenant controller by using the virtualization type table, (c) virtualizing the virtual flow rule into the physical flow rule according to the selected virtualization type, (d) virtualizing the physical rule by using a rule map, and (e) installing the virtualized physical flow rule on the physical switch.
