What is OpenStack Tacker?

Tackeris an official

OpenStack project for

NFV Orchestration and VNF

Management using standards

based architectures

Tacker Project Overview

• Started on NFV Orchestration early 2015

• Announced in OpenStack Vancouver Summit – May, 2015

• First release in Kilo with basic VNF life-cycle management

• Second release in Liberty with Monitoring Framework

• Accepted into OpenStack Big-Tent in March, 2016

• Part of official OpenStack Mitaka

• Closely work with OPNFV and standards bodies like ETSI NFV and OASIS TOSCA

● VNF Catalog

○ repository of VNF descriptors (VNFDs) in a database

● VNF Instantiation and Termination using Heat

○ TOSCA to Heat translation in Tacker

● VNF Configuration injection during instantiation, update and restart

○ Loadable VNF specific mgmt-driver

● Loadable per-VNF Health Monitoring

● Self Healing according to VNFD policy

NFV Information Model / Data Model

•Tacker closely working with OASIS TOSCA NFV Working group

•Based on the just-released CSD03 version of OASIS TOSCA Simple Profile for NFV

•Participating in cross-SDO events

• Introduced TOSCA NFV Profile support into tosca-parser [1]

•Transition from in-built translator to tosca-parser in progress [2]

Enhanced Platform Awareness (EPA)

• VNF placement with performance smarts• CPU-Pinning

• Huge Page

• NUMA awareness

• SR-IOV

• Requires hardware support in underlying cloud resources

Auto Resource Creation

• Supported in TOSCA templates

• Automated Flavor creation based on

CPU/memory/disk/EPA capabilities described in

• Automated Image creation from URL/repository

described in template

• Automated Network/Subnet creation as described in

Tacker VNF Forwarding Graph

• Adding VNF Forwarding Graph Descriptor (VNF FFGD) to Tacker• user-friendly template format for Forwarding Graphs description

• Leveraging elements defined in VNFD templates to:• obtain information regarding Connection Points (CP) and Virtual

Links (VL)

• map high level abstract service types to onboarded VNFs

• Integration networking-sfc driver

• Contributing to networking-sfc integration with OpenDayLight SDN Controller
