1. BoF: Open NFV Orchestration using Tacker
Oct 27,

2. ETSI MANO and Tacker
Tacker is an OpenStack service addressing NFV Orchestration and VNF Manager use-cases using ETSI MANO Architecture

3. Role of NFV Orchestrator
VNFM
NFVO
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

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. Tacker Stackalytics
URL:

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

7. 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?

Tacker can instantiate VNFs only on same OpenStack controller
Operators have multiple OpenStack VIMs (even different VIM versions)
VNF placement on specific target OpenStack VIM
Blueprint: coming soon

9. 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:

10. 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

15. 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
