What is Tacker?

Tacker is the OpenStack project that provides a software based on ETSI NFV-MANO Architectural Framework.

Tackerは、ETSI NFV-MANO Architectural Frameworkをベースにしたソフトウェアを提供するOpenStackプロジェクトです。

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.

Tackerは、OpenStackのようなNFVインフラプラットフォーム上にネットワークサービスや仮想ネットワーク機能（VNF）を展開・運用するための汎用VNFマネージャ（VNFM）とNFVオーケストレータ（NFVO）を構築する公式OpenStackプロジェクトである。ETSI MANO Architectural Frameworkをベースとし、VNFを使用してネットワークサービスをエンドツーエンドでオーケストレーションするための機能スタックを提供します。

First appeared in OpenStack 'Mitaka' release.

When Tacker project was originated to follow the ETSI NFV MANO standards in Liberty release,

VNF Manager

5.3.2 VNF Manager (VNFM)
The decoupling of Network Functions (NFs) from the physical infrastructure resulted in a new set of management functions focused on the creation and lifecycle management of the VNF, handled by the VNF Manager (VNFM).
The VNFM is a functional block with a definition provided in ETSI GR NFV 003.
The VNFM main functions are to provide:

VNF LifeCycle Management (LCM).

VNF configuration management of the configuration parameters of a VNF/VNF Component (VNFC).

VNF information management for the value changes of VNF related indicators.

VNF Performance Management (PM).

VNF Fault Management (FM).

In addition, the VNFM can gather and offer information on the VNF behaviour in the form of VNF indicators. VNF indicators are information supplied by the VNF or the EM.
In order to realize these functions, the VNFM consumes interfaces offered by other NFV-MANO functional blocks. The VNFM maintains the mapping between virtual resources and the VNF instance using them. The VNFM acts upon the virtualised resources that support the VNF functionality, but without interfering with it.
