Network Functions Virtualisation (NFV) Release 2; Management and Orchestration; Functional requirements specification

Network Functions Virtualisation (NFV) adds new capabilities to communications networks and requires a new set of management and orchestration functions to be added to the current model of operations, administration, maintenance and provisioning. The NFV Management and Orchestration (NFV-MANO) architectural framework has the role to manage the infrastructure and orchestrate the resources needed by the Network Services (NSs) and Virtualised Network Functions (VNFs).
 
In order to guide the development of the specification of the interfaces exposed between the NFV-MANO Functional Blocks (FBs), it is important to have a clear and consolidated set of functional requirements to be addressed by the NFV-MANO. The present document is providing functional requirements on NFV MANO e.g. VNF lifecycle management (LCM), NS LCM, virtualised resource management, etc.
 
The functional requirements specified in the present document are mainly derived from functional requirements identified in ETSI GS NFV 002, ETSI GS NFV 003, ETSI GS NFV 004, ETSI GS NFV-MAN 001, ETSI GS NFV-SWA 001, ETSI GS NFV-REL 001 and ETSI GS NFV-INF 001 or derived from concepts defined in these documents.
