Development Time VNF Representations

  • HEAT

  • ETSI NFV SOL001

  • K8S HELM

What VNF TOSCA template flavor(s) to adopt for Dublin (e.g. SOL001 templates vs. AID templates)?

On-Boarding Time Representation 

  • Continue to support SOL001 VNF TOSCA templates

    • Use v2.5.1 of SOL001 specification

Design-Time Representation

  • Continue to support SOL001 specification (for pure ETSI NVF)

    • NOTE - for now, the focus is on VNFD's and PNFD's only. Will need to revisit for specification of NS's

  • Use TOSCA templates for K8S support

  • Continue to support AID (for HEAT only)

Will SDC design tools in Dublin support creation of VNF TOSCA templates based on agreed upon flavor(s) and version(s)?

Design-Time Representation

  • SDC design tools will continue to generate AID TOSCA templates for service definitions

  • No other template flavor will be generated

What VNF TOSCA template grammar version(s) to adopt for Dublin?

On-Boarding Time Representation

  • TOSCA Simple YAML Profile v1.2+

Design-Time Respresention

  • TOSCA Simple YAML Profile v1.2+ for SOL001 compliant templates

  • AID Grammar version - TBD
