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

• 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 THREE

• Goal• Production Readiness

• Themes• Service Assurance (e.g. scaling NS/VNF, SFC, state mgmt, fault mgmt)

• Usability (e.g. logging, metrics, installation, data centre capabilities, APIs, PNF)

• Security (e.g. RBAC, project views, key mgmt)

• Resiliency (e.g. scalability and recovery of OSM)

• CI/CD (Improved Testing Framework, Installation)

OSM Data Models

19

Aligned with ETSI NFV ISG Phase 1 Information Models

• Will work with the NFV community for clarifications, bug fixes (sightings) and feature advances.

• Possible intersect with OSM Release THREE

Analysis underway on ETSI NFV ISG Phase 2 Information Models
