ETSI MANO NFV Orchestration for Telco Service Providers using OpenStack Tacker project. Showcases integration of Tacker to orchestrate Brocade VNFs like 5600 Virtual Router and Connectem vEPC.

1. NFV Orchestration for Telcos
using OpenStack Tacker

2. Agenda
• What is Tacker ?
• Role of VNF Manager (VNFM) and NFV Orchestrator (NFVO)
• Tacker Architecture & Workflow
• Tacker Features
• Roadmap – Mitaka and Beyond

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

4. 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

5. OpenStack Tacker Features
• VNF Catalog
• VNF Lifecycle Management
• Refined MANO API
• Parameterized TOSCA VNFD template
• VNF user-data injection
• VNF configuration injection – during Instantiation and Update
• Loadable Health Monitoring Framework

8. Roadmap – Mitaka and Beyond
• Multi-VIM Support
• Service Function Chaining (SFC) across VNF
• Platform aware VNF Placement
• VNF Auto-Scaling

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

Tacker can instantiate VNFs only
on same OpenStack controller
Today Multi-VIM

10. 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/

11. Platform aware 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)
• Blueprint: coming soon
