Tacker - OpenStack NFV Orchestration

Tacker is an official OpenStack project building a Generic VNF Manager (VNFM) and an NFV Orchestrator (NFVO) to deploy and operate Network Services and Virtual Network Functions (VNFs) on an NFV infrastructure platform like OpenStack. It is based on ETSI MANO Architectural Framework and provides a functional stack to Orchestrate Network Services end-to-end using VNFs.

High-Level Architecture

NFV Catalog

VNF Descriptors
Network Services Descriptors
VNF Forwarding Graph Descriptors

VNFM

Basic life-cycle of VNF (create/update/delete)
Enhanced platform-aware (EPA) placement of high-performance NFV workloads
Health monitoring of deployed VNFs
Auto Healing / Auto Scaling VNFs based on Policy
Facilitate initial configuration of VNF

NFVO

Templatized end-to-end Network Service deployment using decomposed VNFs
VNF placement policy – ensure efficient placement of VNFs
VNFs connected using an SFC - described in a VNF Forwarding Graph Descriptor
VIM Resource Checks and Resource Allocation
Ability to orchestrate VNFs across Multiple VIMs and Multiple Sites (POPs)

Use Cases

vCE

Tacker API can be used by SP's OSS / BSS or an NFV Orchestrator to deploy VNFs in SP's network to deliver agile network services for remote Customer networks

vCPE

Tacker API can be used by SP's OSS / BSS or an NFV Orchestrator to manage OpenStack enabled remote CPE devices to deploy VNFs to provide locally network services at the customer site.

vPE

Tacker API can be used by SP's OSS / BSS or an NFV Orchestrator to deploy VNFs within SP's network to virtualize existing network services into a Virtual Function.

ETSI NFV SPECS

TOSCA for NFV

Tacker uses TOSCA for VNF meta-data definition. Within TOSCA Tacker used NFV profile schema.

TOSCA YAML
- YAML Simple Profile: http://docs.oasis-open.org/tosca/TOSCA-Simple-Profile-YAML/v1.1/csprd02/TOSCA-Simple-Profile-YAML-v1.1-csprd02.html
TOSCA NFV Profile:
- Latest spec is available here: https://www.oasis-open.org/committees/document.php?document_id=56577&wg_abbrev=tosca
- Current latest (as of Oct 2015) is: https://www.oasis-open.org/committees/download.php/56577/tosca-nfv-v1.0-wd02-rev03.doc

Tacker + SFC (Service Function Chaining)

The proposal to enable SFC for Tacker is captured in these slides,
