ETSI MANO and ONAP ETSI Alignment Landscape 

As part of aligning ONAP to ETSI MANO, ONAP supports ETSI standards for packaging, operations and monitoring for managing VNF, PNF and NS.

• For packaging, the SOL004 standard is used for VNF and PNF, the SOL007 standard is used for NS

• Use of the SO007 standard for NS packages is under discussion. 

• VNF, PNF and NS will be described by SOL001 standard.

• For VNF LCM, Package Management, LCM operations and Monitoring, SOL003 standard is used.

• For NS LCM and Package Management, LCM operations and Monitoring, SOL005 standard is used.

• For EM triggered scenarios (LCM, Fault, Performance, Configuration), SOL002 standard is used.

The following diagram depicts the relationship between ETSI MANO and ONAP ETSI Alignment.

Requirements

For ONAP ETSI MANO alignment, the following scenarios need to be fulfilled.

• ONAP shall support ETSI standards for packaging, distribution, LCM operations, security and monitoring for managing VNF, PNF and NS.

  • ONAP shall support SOL004 and SOL007 package onboarding and distribution (VNFSDK, SDC, SO, VFC and others)

  • ONAP shall support ETSI Package security and validation (VNFSDK, SDC, SVNFM, VFC, External NFVO)

  • ONAP shall support ETSI package catalog in runtime (SO, ONAP-ETSI Catalog Manager)

• External VNFM scenarios :

  • ONAP shall ingest and save (without modification) a SOL004 CSAR package for later consumption by a SOL003 compliant VNFM/NFVO (VNFSDK, SDC, ONAP-ETSI Catalog Manager)

  • ONAP shall ingest and interpret a SOL001 compliant VNFD in order to design an ONAP Service (VNFSDK, SDC)

  • ONAP shall understand resource requirements in the VNFD for each deployment and scaling level (SO, SOL003 Adapter, A&AI, OOF)

  • ONAP shall support a SOL003 compliant SBI to plug in external VNFM (SO, SOL003 Adapter, VF-C)

  • ONAP shall have a mechanism for specifying that a VNF instance should be runtime managed by a particular VNFM type (design time)  and instance (run time) (SO, SOL003 Adapter, OOF, A&AI)

  • ONAP shall have a way to inventory a VNF that was deployed using an external VNFM (SO, A&AI)

• External NFVO scenarios :

  • ONAP shall ingest and save (without modification) a SOL007 Network Service Package. (VNFSDK, SDC) for later consumption by a SOL005 compliant NFVO

  • ONAP shall ingest and interpret a SOL001 compliant NSD (SDC)

  • ONAP shall ingest and save (without modification) a SOL004 CSAR package for later consumption by a SOL003 compliant NFVO (VNFSDK, SDC, ONAP-ETSI Catalog Manager)

  • ONAP shall ingest and interpret a SOL001 compliant NSD/PNFD in order to design an ONAP Service (VNFSDK, SDC)

  • ONAP shall be able to convert an ONAP Service into a SOL001 compliant NSD (SOL005 Adapter)

  • ONAP shall have a SOL005 compliant SBI (SO, SOL005 Adapter, VF-C, External NFVO)

  • ONAP shall have a mechanism for specifying that a Service should be runtime managed SO, VF-C or external NFVO (SDC, SO)

  • ONAP shall have a way to inventory a Service that was deployed as a Network Service using an external NFVO (SO, A&AI)

  • ONAP shall be able to design a Service that includes some VNFs and some hierarchy (nested) of Services (NSs) (SDC)

  • ONAP shall have a way to Deploy and Life Cycle Manage a Service that includes some VNFs and some hierarchy of Services (NSs) (SO, A&AI, SND-C, SOL003 & SOL005 Adapters)

• ONAP shall support: 1) VNFM-triggered VNF Configuration, 2) EM-triggered VNF/VNFC LCM and 3) VNF Indicator Interface, based on SOL002 standard (SOL002 Adapter, APPC, DCAE, Policy)

Overall Use Cases

• ETSI Package Management Use Case

  • SOL004/SOL007 VNF/PNF/NS Package includes SOL001 VNFD/PNFD/NSD with the original vendor package

  • SOL004/SOL007 VNF/PNF/NS Package Security

• ONAP-ETSI Catalog Management Use Case

  • ONAP-ETSI Catalog API Management

  • ONAP-ETSI Catalog Database

  • SO ETSI Catalog DB enhancement, by leveraging ONAP-ETSI Catalog Management Microservices

• ETSI-Alignment SOL003 Adapter Use Case

  • Package Management for SVNFM

  • Granting Enhancement with HPA

  • Query

  • Modify (TBD)

  • Policy-based Scaling (Stretch goal)

  • Security between the Adapter and VNFMs

  • Additional operations will be determined

• ETSI-Alignment SOL005 Adapter Use Case

  • Package Management for External NFVO

  • Security between the Adapters and External NFVOs

  • Additional operations will be determined

• ETSI-Alignment SOL002 Adapter Use Case
  
  

  • Security between the Adapters and VNFM

  • SOL002 operations

• vCPE use cases plan to be used.

<describe common functions>

Open Issues

• Mapping between SOL001 VNFD to SDC AID DM, including ScalingAspect+Delta and VF-Module - Not all VNFD needs to be transformed to the SDC AID DM

• How does ONAP support vendor-specific SVNFM security (authentication/authorization)?

• SOL007 (NS package) support is under discussion

• Certificate generation and distribution by AAF

• SOL005 Adapter requirements for the ONAP-ETSI Catalog Manager

• Where (SOL003 Adapter, or SO NFVO) do we support VNF software image transfer to VIM?

  • ONAP-ETSI Catalog Manager stores the software image and forwards it to VIM through the Adapter and VNFM.
