3. What is Tacker?
• Tacker is an OpenStack based NFV Orchestration
framework used to deploy and operate Virtual
Network Functions (VNFs).
• Tacker is compatible with ETSI NFV Architectural
Framework and provides full functional stack to
manage VNFs and orchestrate end-to-end
Network Services on various VIMs.

tacker components
To run a complete tacker system, it
needs following external softwares:
1. mistral, a workflow engine
2. Mysql, the NFV catalogue and
resource states storage
3. AMQP message system, which
connects tacker server, mistral
workflow tasks and tacker
conductor
4. keystone, identity manager
5. babican, the credential storage for
target VIMs
The consistent components of tacker repos:
1. python-tackerclient, openstack command plugin
2. tacker horizon, tacker resources GUI
3. tacker server, MANO API implementer
4. tacker conductor, policy action executor

6. New features ( https://docs.openstack.org/releasenotes/tacker/queens.html)
• Multiple flow classifiers per VNF forwarding graph (VNFFG).
• Symmetric VNFFG.
• VNFFG updating.
• VNFFG without flow classifiers.
• Reusing VNFs in VNFFG.
• Zabbix plugin for monitoring VNF’s application.
• Kubernetes VIM.
• Container based VNFs.
