Abstract: The inventive concept described herein relates to a performance analysis apparatus of VNF in a NFV platform and a method thereof that may analyze the performance of VNFs in an NFV platform and a factor that causes the performance to be degraded. A performance analysis apparatus of VNF that analyzes performance of the VNF within a NFV platform includes an NFV environment constituting unit generating a service chain composed of VNFs, using a VNF policy configuration of the VNF and configured to deploy the VNFs corresponding to the service chain in the NFV platform, a performance monitoring unit monitoring internal forms of the VNFs by measuring a performance feature of each component within the NFV platform and a performance feature for the service chain, and an analysis unit specifying a performance degradation VNF that degrades performance in the service chain to derive a cause.
