BoF:
Open NFV Orchestration using
Tacker
https://etherpad.openstack.org/p/mitaka-tacker-design-summit-bof
Oct 27, 2015.01
ETSI MANO and Tacker
Tacker
is an OpenStack
service addressing
NFV Orchestration
and VNF Manager
use-cases
using ETSI MANO
Architecture
Role of NFV Orchestrator
VNFM
• 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
NFVO
• 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
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
Tacker Stackalytics
Update on Liberty - in-flight
• VNF Service Function Chaining APIs (tacker-sfc)
• VNF Auto-Scaling
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?

VIM 0
(local OpenStack

Tacker can instantiate VNFs only on
same OpenStack controller
VIM 0
(default – local

VIM 1
(OpenStack
Controller)
VIM 2
(OpenStack
Controller)
• Operators have multiple OpenStack VIMs (even
different VIM versions)
• VNF placement on specific target OpenStack VIM
• Blueprint: coming soon
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/
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

Backup
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
