4.1 Configuration management in the context of NFV

3GPP Configuration Management (CM) has system modification functions and system monitoring functions (as described in [3]).

The decoupling of software and hardware in NFV gives rise to the need to model the VNF application specific parameters (i.e. 3GPP service related) by 3GPP whilst modelling the VNF non-application specific parameters (i.e. non-3GPP service related) in ETSI GS NFV-IFA 008 [5].

For Configuration Management, NM and EM manage NEs and NRs and the related configuration parameters (e.g. identification, port, neighbour relation) which are modelled as the MO(s) and MO attributes. The MO attributes, which are defined by 3GPP, typically are VNF application specific parameters.
