  /**
   * <p>Tacker - OpenStack NFV Orchestration</p>
   *
   * <p>Tacker is an official OpenStack project building a Generic VNF Manager (VNFM) and a NFV Orchestrator (NFVO) to deploy and operate
   * Network Services and Virtual Network Functions (VNFs) on an NFV infrastructure platform like OpenStack.
   * It is based on ETSI MANO Architectural Framework and provides a functional stack to Orchestrate Network Services end-to-end using VNFs.</p>
   *
   * <p>VNFD Stands for Virtual Network Functions Descriptor. This is the VNF Catalog Management (TOSCA-YAML Template) API Service..</p>
   *
   * <p>
   * <u>NFV Catalog</u>:
   * <ul>
   * 		<li>VNF Descriptors.</li>
   * 		<li>Network Services Decriptors.</li>
   * 		<li>VNF Forwarding Graph Descriptors.</li>
   * </ul>
