ETSI MANO and 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

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?

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/

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
