Solution Set

4 General descriptions p. 6

For VNF Fault Management Stage 3 solution over Itf-N, the Alarm IRP SS is applicable. The overall description of Alarm IRP SS is specified in TS 32.111-6.The semantics of Alarm IPR SS are specified in Alarm IRP Information Service TS 32.111-2. Three solution sets are contained in [3], which are the CORBA Solution Set, the XML definitions and the SOAP Solution Set.

For VNF Fault Management Stage 3 solution over Ve-Vnfm reference point, the corresponding RESTful solution of ETSI GS NFV-SOL 002 [5] shall be used as specified in clause 5.2.

5 Solution Set Definitions p. 6

5.1 Itf-N p. 6

For Itf-N VNF alarm management, the following Solution Set Definitions defined by AlarmIRP which is specified in TS 32.111-6 shall be used:

Annex A of TS 32.111-6 provides the CORBA Solution Set.
Annex B of TS 32.111-6 provides the XML Definitions.
Annex C of TS 32.111-6 provides the SOAP Solution Set.

5.2 Ve-Vnfm-em p. 6

For Ve-Vnfm-em VNF alarm management, the following shall be used:

the RESTful API URI structure and supported content formats specified in clause 4.2 of ETSI GS NFV-SOL 002 [5], and
the RESTful API common procedures specified in clause 4.3 of ETSI GS NFV-SOL 002 [5], and
the RESTful API common data types specified in clause 4.4 of ETSI GS NFV-SOL 002 [5], and
the VNF FM RESTful API resource structure, methods, resources, data model and handling of errors specified in clause 7 of ETSI GS NFV-SOL 002 [5].
