[[ETSI]] has already indicated that an important part of controlling the NFV environment be done through automated orchestration. NFV Management and Orchestration (NFV-MANO) refers to a set of functions within an NFV system to manage and orchestrate the allocation of virtual infrastructure resources to virtualized network functions (VNFs) and network services (NSs). They are the brains of the NFV system and a key automation enabler.
The main functional blocks within the NFV-MANO architectural framework ([https://www.etsi.org/deliver/etsi_gs/NFV/001_099/006/02.01.01_60/gs_nfv006v020101p.pdf ETSI GS NFV-006] )are:
* Network Functions Virtualisation Orchestrator (NFVO);
* Virtualised Network Function Manager (VNFM);
