Problem aiming to solve

Incorporate the changes to the ETSI VNF Descriptor information model from version 2.5.1 to version 2.7.1 .

Changes

Types:

  1. Add new type VipCpd which is a generalization of type Cpd and describes a requirement to allocate one or a set of virtual IP addresses.

    1. Attribute

      Qualifier

      Cardinality

      Content

      Description

      intCpd

      M

      0..N

      Identifier (Reference to VduCpd)

      References the internal VDU CPD which is used to instantiate internal CPs. These internal CPs share the virtual IP addresses allocated when a VipCp instance is created from the VipCpd.

      vnfExtCpd

      M

      0..N

      Identifier (Reference to VnfExtCp)

      References the VNF external CPD which is used to instantiate external CPs. These external CPs share the virtual IP addresses allocated when a VipCp instance is created from the VipCpd.

      vipFunction

      M

      1

      Enum

      It indicates the function the virtual IP address is used for. Permitted values: high availability, load balancing. See note.

      (inherited attributes)




      All attributes inherited from Cpd.

  2. Add new type CheckSumData which provides a mechanism to verify SwImages

    1. Attribute

      Qualifier

      Cardinality

      Content

      Description

      algorithm

      M

      1

      String

      Species the algorithm used to obtain the checksum value. See note

      hash

      M

      1

      String

      Contains the result of applying the algorithm indicated by the algorithm attribute to the data to which this ChecksumData refers.

  3. Add new type VnfInterfaceDetails which specifies the details of an interface produced by the VNF on the Ve-Vnfm  reference point

    1. Attribute

      Qualifier

      Cardinality

      Content

      Description

      interfaceName

      M

      1

      Enum

      Specifies an interface produced by the VNF.


      Valid values:

      • VNF_CONFIGURATION
      • VNF_INDICATOR

      cpdId

      M

      1..N

      Identifier (Reference to VnfExtCpd)

      References one or more CPDs from which to instantiate external CPs through which interface endpoints on the VNF side can be reached by the VNFM.

      See note.

      interfaceDetails

      M

      0..1

      Not Specified

      Provide additional data to access the interface endpoint (e.g. API URI prefix).






Other changes:

  1. VDU::configurableProperties - Cardinality changed to 0..1; cardinatlity 0 when the VNFCs do not have configurable properties
  2. CPD::cpProtocol & CPD::trunkMode - Cardinality changed to allow 0
  3. VduCpd::vnicType: Added SMART-NIC as an allowable value
  4. SwImageDesc:Provider - New attribute of type string with cardinality 0..1 which describes the provider of the software image.
  5. VnfDf:supportedVnfInterface - New attribute of type VnfInterfaceDetails with cardinality 0..N which indicates which interfaces the VNF produces and provides additional details on how to access the interface endpoints.
  6. VnfConfigurableProperties::vnfminterfaceinfo - New attribute with cardinality 0..1 which contains info enabling access to the NFV-MANO interfaces produced by the VNFM <Expect to remain as Experimental since the type is still undergoing discussion in ETSI>
  7. VnfConfigurableProperties::vnfmOauthServerinfo - New attribute with cardinality 0..1 which contains info to enable discovery of the authorization server protecting access to the VNFM interfaces
  8. VnfConfigurableProperties::vnfOauthServerinfo - New attribute with cardinality 0..1 which contains info to enable discovery of the authorization server to validate the access tokens provided by the VNFM when the VNFM accesses the VNF interfaces
  9. Updated all of the 2.5.1 references to 2.7.1
  10. Provided the gendoc for the classes that are in the "common" section.
