Download as PPTX, PDF9 likes3,962 views
The document discusses Tacker, an OpenStack service for NFV orchestration and VNF management based on the ETSI MANO framework. It outlines Tacker's architecture, features, and roadmap, highlighting its roles in VNF instantiation, monitoring, and lifecycle management. Upcoming enhancements include multi-VIM support and platform-aware VNF placement strategies.
NFV Orchestration for Telcos using OpenStack Tacker
- 1. NFV Orchestration for Telcos using OpenStack Tacker
- 2. Agenda • What is Tacker ? • Role of VNF Manager (VNFM) and NFV Orchestrator (NFVO) • Tacker Architecture & Workflow • Tacker Features • Roadmap – Mitaka and Beyond
- 3. What is Tacker? Tacker is an OpenStack service addressing NFV Orchestration and VNF Manager use-cases using ETSI MANO Architecture
- 4. 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
- 5. OpenStack Tacker Features • VNF Catalog • VNF Lifecycle Management • Refined MANO API • Parameterized TOSCA VNFD template • VNF user-data injection • VNF configuration injection – during Instantiation and Update • Loadable Health Monitoring Framework

- 8. Roadmap – Mitaka and Beyond • Multi-VIM Support • Service Function Chaining (SFC) across VNF • Platform aware VNF Placement • VNF Auto-Scaling
- 9. Multi-VIM • Operators have multiple OpenStack VIMs (even different VIM versions) • VNF placement on specific target OpenStack VIM • Blueprint: coming soon Tacker VIM 0 (default – local OpenStack Controller) VIM 1 (OpenStack Controller) VIM 2 (OpenStack Controller) VIM 0 (local OpenStack Controller) Tacker Tacker can instantiate VNFs only on same OpenStack controller Today Multi-VIM
- 10. 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/
- 11. Platform aware 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) • Blueprint: coming soon
