The ETSI-based CNF support is conforming to IFA 011, IFA029 and IFA040. Based on the ETSI specification progresses, we plan to apply necessary changes.

...

• Mapping VNF-Descriptor to SDC AID DM?
• How to identify Pods in AAI?
• Package multiple NFs into a single CNF and manage them independent from each other. (Deployment flavors, aspects, …)
• Building an NF which spans multiple CNFs. The single CNF would not necessarily be a self-sufficient entity anymore. (Network Services)
• CI/CD based upgrades of microservices within a CNF. (ChangeVnfPackage)

ONAP ETSI-Alignment Overall Architecture (Various Options)

Model-Driven Orchestration

...

(various options)

• SO supports dual CNF support: one is the CNF direct leveraging K8S Adapter, K8S Plugin (in MultiCloud) path and one is the ETSI-Alignment path, leveraging SOL005 Adatper, NFVO, SOL003 Adapter and VNFM.
• SDC supports a common onboarding mechanism for both CNF paths

• The VNFD introduces a new resource template OsContainerDesc for OS containers.
• The ResourceDefinition information element used in the grant request message needs to be enabled to reference resource templates for OS containers, the same way as the other resource template
• Enhance the ResourceDefinition information element attributes with references to OS container resource definition types and resource templates.
  • OsContainer Type is added
  • Reference to OsContainerDesc is added

IFA 011 411 Draft Proposal addition to VipCpd

• VipCpd in SOL001 2.7.1 describes the mapping of a “virtual IP” address to connection points in a VNF.
  • Either HA (Active/Standby) or Load Balancing.

Proposed for 4.1.1

• Use VipCp to model K8S service connectivity (under discussion)
• AdditionalVipData – Expose information about a port and service data
  • Name of the VIP (uService)
  • L4 Protocol exposed (TCP, UDP, SCTP, )
  • Port exposed
  • intCpd attribute is optional (changes from 1..N to 0..N)
• Service Data
  • L7 info (unspecified in VNF-D)
