Claim of US Patent No. 10,341,195

1. A method of operating a Network Function Virtualization (NFV) Software Defined Network (SDN) to control NFV resources consumed by Virtual Network Functions (VNFs) that support a data service, the method comprising:an NFV Infrastructure (NFVI) executing SDN application VNFs, SDN controller VNFs, and NFVI virtual Switches (vSWs) to support the data service,
the SDN application VNFs, the SDN controller VNFs, and the NFVI vSWs responsively transferring SDN Key Performance Indicators (KPIs) to an NFV Management and Orchestration (MANO) Virtual Infrastructure Manager (VIM) and to a MANO VNF Manager (VNFM);
the MANO VIM receiving the SDN KPIs and transferring the SDN KPIs to a MANO KPI server;
the MANO VNFM receiving the SDN KPIs and transferring the SDN KPIs to the MANO KPI server;
the MANO KPI server processing the SDN KPIs to generate VNF control data to darken one of the SDN VNFs and processing the VNF control data to generate and transfer NFV control data to darken the one SDN VNF; and
the NFVI darkening the one SDN VNFs responsive to the NFV control data by restricting access to NFVI hardware for the one SDN VNF.
