The OpenStack Tacker Project and SDN/NFV MANO: Craig Stevens, Brocade

  1. 1. The OpenStackTacker Project and SDN/NFVMANO
  2. 2. Agenda • ETSI NFV MANO • NFV Orchestration • VNF Management • Bringing SDN and NFV together • What is TOSCANFV • What is Tacker?
  3. 3. ETSI NFVArchitecture
  4. 4. NFV Orchestrator(NFVO) © 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 4 § Network Service Orchestration using a collection of VNFs and Forwarding Graphs § Templatize an end-to-end Network Service using decomposed VNFs § Resource Checks and Resource Allocation § VNFs connected using Forwarding Graphs o Described in a VNF Forwarding Graph Descriptor o Render VNF Forwarding Graphs using SDN Controller or a SFC API § Ability to orchestrate VNFs across Multiple VIMs § PNF connectivity and configuration in end to end network service orchestration
  5. 5. VNFManager(VNFM) © 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 5 § VNF Catalog – repository of VNF descriptors (VNFDs) in a database § VNF Instantiation and Termination § VNF Monitoring - Health and Performance Indicators § Self Healing and Auto Scaling § VNF Configuration injection during instantiation § VNF Image management § Supportboth simple and complex VNFs § Enforce placement policy § ensure efficient placement of VNFs (NUMA, CPU Pinning)
  6. 6. Virtual Infra Manager(VIM) © 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 6 § Responsible for controlling and managing the NFVI compute, storage and network resources § Usually within one operator’s Infra Domain (i.e. NFVI-POP) § Exposes Northbound APIs(i.e. used by VNFM) § OpenStack is an example of a VIM
  7. 7. Bringing SDN/NFV together Open Modular architecture allows the platform to evolve over time (no monolithic proprietary lock-ins) Service APIprovidesa simple programmatic interface forall network services SDN WAN for proven scalability and reliability Open Source projectswith broad,active communities for componentsthat enable interoperability 7 WAN PCE Application leveragesopensource ODL SDN Controllerplatform See Demonstration at the Brocade Stand
  8. 8. What is TOSCA NFV? • Topology andOrchestration Specification for CloudApplications(TOSCA) comes from the OASIS open standards consortium and has been used in the applications ecosystem since 2014 • TOSCA NFV is a data modeling andtemplating languagefor NFV services allowingyou to define: Topology, Composition, Lifecycle, Portability • Is very different toYang,Yang is good for network device configuration not goodfor above complex relationships • Some Open Source Implementations: Senlin, Tacker, Parser,Alien4cloud, Cloudify,Aria TOSCANFV Specification: Source: TOSCA NFVSpecification
  9. 9. What is Tacker? Tacker is an OpenStack project for NFV Orchestration and VNF Management using ETSI MANO Architecture
  10. 10. TackerStackalytics
  11. 11. Tacker (VNF Management) • Tacker is an OpenStack project • VNF Catalog • VNF Lifecycle Management • Thru pluggable infra driver • VNF Configuration • SDN Controller • config-drive • Custom management driver • VNF Health Monitoring • North Bound API • VNF Image update management • Support both simple and complex VNFs
  12. 12. Future – Mitaka and Beyond • Multi-Site Support • Efficient VNF placement policy • Automatic Resource Creation (flavor, image, network) • Forwarding Graphs across VNF’s using SFC API’s • TOSCA NFV Profile Parser Integration • Basic Network Service Descriptor (NSD) support • VNF Auto-Scaling
  13. 13. Summary • Open Sourced componentscan accelerate adoption andprovide strong communitysupport (i.e. Linux, OpenStack and OpenDaylight) • An open and modular SDN/NFV architectureis key to ensure longevity of the platform and avoid vendor lock-inwhile allowing the customer to pick best of breed products. • TOSCA NFV is really good at describingcomplex, application relationships betweennodes as the data modellinglanguage for networkservices (used in both the NFVO and the VNFM) • Tacker is an open sourced project under Openstackthat providesVNF Management today andhas plans for some NFVO functions in the future

  15. 15. Thank you!
  16. 16. TackerVNF Catalog • VNF definition using TOSCA templates ‒ Describes the VNF attributes ‒ Glance image IDs ‒ Nova properties - Placement, CPU Pinning, NUMApolicy, etc ‒ Performance Monitoring Policy ‒ Auto-Healing Policy • Support for multiple VMs per VNF (VDUs) • APIs to on-board and maintain VNF Catalog • VNFDs are stored in Tacker DB Repository of VNF Descriptors (VNFD)
  17. 17. Tacker - VNF Life Cycle Management • Tacker API deploysVNF from the VNF Catalog • Pluggable infra driver framework ‒ Nova, Heat (default) ‒ HEAT Driver uses in-built TOSCAto HEAT convertor ‒ Instantiates one or more VMs described in TOSCA • Terminate VNF will delete all VMs associated with VNF instance Instantiation and Termination of VNF’s
  18. 18. Tacker - VNFAuto-Configuration • Tacker provides Extensible Management Driver Framework • Facilitates VNF configuration based on Service selection • Inject initial configuration using: ‒ SDN Controller using NetConf/YANG ‒ config-drive ‒ custom mgmt-driver: connect using ssh / RESTapiand apply configuration • • Update configuration in active state • Extendable! Bootstrap and start-up config of VNF
  19. 19. Tacker – VNF Monitoring VNF Self-Healing • Tacker health check starts as VNF becomes ready • Ongoing network connectivity check • Auto-restart on failure – based on VNFD policy • Extendable Vendor and Service specific Health Monitoring Driver framework
