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
