OSM Scope & Mapping to ETSI NFV MANO
4
• Automated end-to-end Service Orchestration
• Superset of ETSI NFV MANO
• Plugin model for integrating multiple SDN controllers
• Plugin model for integrating multiple VIMs
• Plugin model for integrating monitoring tools
• Integrated Generic VNFM with support for integrating Specific VNFMs
• Support for Physical Network Function integration
• Greenfield and brownfield deployments
Run-Time Scope
• Network Service Definition (CRUD operations)
• Model-Driven Environment with Data Models aligned with ETSI NFV
• VNF Package Generation
• GUI

Release FOUR Highlights
• Consistent themes spanning releases – Release brings shift in focus• Service Assurance (e.g. updates to running services, VNF scaling, SFC, fault mgmt,
policy)• Usability (e.g. consolidated logging, metrics correlation, platform updates)
• Security (e.g. key management)• Resiliency (e.g. scalability and recovery of OSM)• CI/CD (e.g. expanded suite of tests, Installation to include Image, LXD, Docker, Snap)
• New Themes:• Ecosystem Development (catalogues of "validated" VNFs)
• Documentation• Container based VNF deployments
• Note: Priority to be given to completion and stability
