NFV Orchestration for Telcos using OpenStack Tacker

Agenda

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

What is Tacker?

Tacker is an OpenStack

service addressing

NFV Orchestration

and VNF Manager use-

casesusing ETSI MANO

Architecture

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

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

Roadmap – Mitaka and Beyond

• Multi-VIM Support• Service Function Chaining (SFC) across VNF• Platform aware VNF Placement• VNF Auto-Scaling

Multi-VIM

• Operators have multiple OpenStack VIMs (even different VIM versions)

• VNF placement on specific target OpenStack VIM

• Blueprint: coming soon

Tacker

Tacker can instantiate VNFs only on same OpenStack controller

Today Multi-VIM

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/

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
