This paper proposes efficient VNF management method using VNF Group Table in NFV (NFV : Network Function Virtualization), which is gaining attention from many network operator. ETSI ISG NFV WG is researching NFV. It refers to concept of utilizing network function in server OS rather than the equipment. Currently, ETSI ISG WG are divided into six groups, is standardizing, but need to study on the basis of traffic classification aspects or performance metrics. Therefore, in this thesis, research is conducted to create and utilize the VNF Group Table at NFV MANO to propose efficient VNF management techniques in terms of traffic statistics from NFV management.
