SO Plug-in Support for VNFM

• Presentation Slide Deck: Dublin Architecture Planning Meeting#Agenda
• JIRA ONAPARC-310  ONAPARC-310 - Getting issue details... STATUS   (SO Adapter which uses SOL003 to connect to S/G VNFM)

• Leverage ETSI standards for VNF LCM in SO
• Build SO VNFM Adapter
  • Use SOL003 APIs for VNFM communication
  • Support operation such as create, instantiate, scale, etc.
• Enhance SO BPMN workflows and recipes
  • Pass VNF LCM requests to VNFM using the VNFM Adapter
• Scale out VNF/VF Module based on policy
  • Enhance VNFM Adapter for VES event
  • Enhance Policy Framework for scaling decisions
  • Enhance SO workflows for VNF/VF Module Scale out
• Instantiation Use Case
• 

• The following diagram depicts the component architecture.
• The VNFM Adapter will be a SO sub-component; packaged as a docker and running in a container.
