3. VDU
Two VDU design principles:
1,flat method
2,composition method

4. tosca.nodes.nfv.VDU.VirtualStorage
This solution aligns with VNFD info model as defined in IFA011, but there are problems of misalignment with TOSCA existing features
Three suggestions:
1, delete all the content of VirtualStorage in the document if agreement can not meet before the deadline (May 10)
2, wait the response from Bruce and IFA if IFA decide to make the change based on TOSCA definition
3, create the new relationship based on Matt suggested in Feb

5. Deployment flavour Potential proposals from TOSCA NFV Adhoc group
VNF Package contains:
the VNF descriptor (VNFD) that defines metadata for package onboarding and VNF management
Artifacts:
the software images needed to run the VNF
optional additional files to manage the VNF (e.g. scripts, vendor-specific files etc.)
Is digitally signed and delivered by the VNF provider as a whole
Is immutable (protected from modification)
Is stored in a repository by the NFVO
Can be accessed by VNFM
Option 1
Option 2

Discussion:
Option 1: Single VNF package contains all of VNFD(s) + all of supported artifacts + manifest file. Or,
Option 2: Single VNF package contains a VNFD + all of supported artifacts + manifest file. If multiple DFs has to be supported, multiple VNF packages are needed.

6. Deployment flavour Common understanding from NFV&SDN adhoc
Current working assumption from OASIS TOSCA NFV adhoc
Support single DF per TOSCA service template .
Support one or more TOSCA service templates in the CSAR VNF package.
1 TOSCA Service Template = a VNFD with a single DF.
CSAR package contains one or more TOSCA service templates. (option 1 and option 2 can both support)
For option 1
All VNFDs have the same VNFD Identifier (GUID).
“flavour_id” will be used to identify which VNFD (service template)
