Tacker is an OpenStack service that addresses NFV Orchestration and VNF Manager use cases using ETSI MANO architecture. It supports VNF instantiation and termination, monitoring, auto-scaling, configuration, and network service orchestration using VNF forwarding graphs. Features in the Liberty update include improved VNF lifecycle management, transition to MANO APIs, and initial VNF service function chaining APIs. Future work may include multi-VIM support, enhanced VNF placement, expanded service function chaining, and support for non-VM network functions.

3. Role of NFV Orchestrator
• VNF Instantiation and Termination
• VNF Monitoring - Health and
Performance Indicators
• Self Healing and Auto Scaling
• VNF Configuration using Element
Management Systems (EMS)
• VNF Image update management
• Support both simple and complex
VNFs
• Network Service Orchestration using a
collection of VNFs and Forwarding Graphs
• Uses VNFM for VNF Placement – possible
across multiple VIMs
• Resource Checks and Resource Allocation
• Spans Physical NFs and Virtual NFs
• Render VNF Forwarding Graphs using SDN
Controller or a SFC API
VNFM NFVO

4. Tacker Features / Liberty Update
• VNF Lifecycle Management – usability enhancements
• Transition to MANO API
• Loadable Health Monitoring Framework
• Parameterized TOSCA VNFD template
• VNF user-data injection
• VNF configuration injection – during Instantiation and Update
• Coming together as a community

5. Update on Liberty - in-flight
• VNF Service Function Chaining APIs (tacker-sfc)
• VNF Auto-Scaling

6. Mitaka and Beyond – Need your inputs
• Multi-VIM Support
• Enhanced VNF Placement
• Service Function Chaining (SFC) across VNF
• Go beyond VM based Network Functions (NFs) to orchestrate
• Physical NFs – existing H/W investments
• Container based NFs – any real needs?

7. Multi-VIM
• Operators have multiple OpenStack VIMs (even
different VIM versions)
• VNF placement on specific target OpenStack VIM
• Blueprint: coming soon

8. Tacker SFC
• Basic VNF Service Function Chaining APIs
• Precursor to VNF Forwarding Graph support
• APIs to
• Define flow classification rules
• Easy to render flow chains across instantiated VNFs
• Initial user – OPNFV SFC PoC
• Blueprint:
• https://review.openstack.org/#/c/228007/

9. Enhanced VNF Placement
• VNF placement with NFV smarts
• Nodes with host-passthru / host-model
• PCI pass through
• NUMA awareness
• vhost
• SR-IOV
• VNFD template enhancements
• flavors, neutron-ports (pci/sr-iov), glance
• Blueprint: coming soon

13. Backup

14. Why generic NFVO / VNFM ?
• Most NVFO / VNFM functions are generic
• VNF specific delta can be addressed using drivers and plugins
• Avoids vendor lock-in
• Encourages NSD and VNFD template standardization
