A.4 Utilization of interface to NFV-MANO by the producer of management services

28.5333GPPArchitecture frameworkManagement and orchestrationRelease 17TS

In this deployment scenario the producers of the network slice subnet related management services and NF related management services are also consuming the management interfaces provided by the NFV-MANO:

– -VNF PM, FM and LCM

– Network service PM, FM and LCM

These interfaces are provided via the Os-Ma-nfvo and the Ve-Vnfm-em reference points as specified in the following specifications:

– Configuration Management (CM): TS 28.510 [11], TS 28.511 [12], TS 28.512 [13], TS 28.513 [14],

– Fault Management (FM): TS 28.515 [15], TS 28.516 [16], TS 28.517 [17], TS 28.518 [18],

– Performance Management (PM): TS 28.520[19], TS 28.521 [21], TS 28.522 [22], TS 28.523 [23],

– Life Cycle Management (LCM): TS 28.525[24], TS 28.526 [25], TS 28.527 [26], TS 28.528 [27].

In this deployment scenario:

– the entity denoted as NSSMF, is capable of consuming the VNF LCM and network service LCM related services provided by the NFV-MANO (NFVO). Same entity is also a producer of the network slice subnet related management services.

– the entity denoted as NFMF (NF Management Function), is capable of application level management of VNFs and PNFs and is a producer of the NF Provisioning service that includes Configuration Management (CM), Fault Management (FM) and Performance Management. Same entity is consumer of the NF Provisioning service produced by VNFs and PNFs.

Figure A.4.1 The deployment scenario for network slice subnet management with interface to NFV-MANO

The use case Network slice subnet instance creation in the clause 5.1.2 of the TS 28.531 [8] shows example of interaction between:

– the consumer of the network slice subnet related management services (e.g. network slice subnet provisioning service) and the NSSMF as the producer of the network slice subnet related management services.

– the NSSMF and the NFMF.

and also, the interaction between:

– the NSSMF and the NFV-MANO,

– the NFMF and the NFV-MANO.

NOTE: Figure A.4.1 shows an example of a deployment scenario, not all scenarios are captured by this figure.
