Proposed R9+ VNF/CNF Data Model Based on ETSI SOL001 v4.2.1

Proposed R9+ VNF/CNF Data Model Based on ETSI SOL001 v4.2.1

Jun 07, 2021

The following describes Data Model based on the ETSI v4.2.1 SOL001 VNFD with CNF support.

  • 2.7.x for backward compatibility during SDC onboarding + 4.2.1 with CNF

    • If the type is changed, separate properties for 2.7.x and 4.2.1 will be used

VNF Data Model

  • property "vnfm_info" constraint pattern: "(etsivnfm:v[0-9]?[0-9]\.[0-9]?[0-9]\.[0-9]?[0-9]$)|([0-9]:[a-zA-Z0-9.-]$)"

    • values must be in format etsivnfm:v3.3.1 or <int>:<string>

    • this is not enforced by constraint in type definition in ONAP

  • property "vnf_profile" has not changed, but it is commented out in existing version in ONAP 

  • new attribute "scale_status" added
