The structure for distributed virtual resource control to provide agile network service in NFV

In NFV framework, the orchestrator and VIM know the decomposition details of the network service. However, we assume that an additional VNF VM, which represents a virtualized VNF instance, is to be increased, VNFM to provide agile network service, which is in charge of the scaling of the service component, must know how to add more computing and overlay network resources, but it does not. In order to solve the problem, we propose specific VNFM by using CVNF VM, which will allow direct control of data plane resources and instances and enable the separation of control plane and data plane network function designs in the NFV framework. The new procedure for initializing and scaling VNF instance to support specific VNFM is suggested.
