Presentation Transcript

  1. Mapping between NFV model and TOSCA Shitao li

  2. NFV model The NFV model of VDU and VNFD are fully aligned with TOSCA composition concept.

  3. Attributes of the VNFD information element Attributes of the Vdu information element reference reference

  4. Mapping between VNFD model defined in NFV and TOSCA

  5. Mapping between VDU model defined in NFV and TOSCA

  6. Suggestion 1，using a service template to describe a VDU, and using the substitution mapping feature to abstract the VDU to be a new VDU node type. 2, Defining virtualComputeDesc and virtualStorageDesc in the DSL_definitions section in a VNFD service template, so multiple VDUs can reference the same virtualComputeDesc or virtualStorageDesc. 3, Defining swImageDesc as a artifact in a VDU.

  7. Thank you!
