+
__NOTOC__
−
Tacker is a project developing a framework to simplify hosting of services in virtual and physical appliances. The framework relieves service developers of having to, themselves, implement functionality to manage devices that host service instances.
 
  
−
The capabilities and functionality envisioned for Tacker are:
+
= Tacker - OpenStack NFV Orchestration =
−
* Device inventory to keep track of available devices
 
−
* Template constructs to describe and categorize devices of different types
 
−
* Lifecycle management of virtual machines and containers
 
−
** This includes maintenance of VM pools that can hide boot latency, thus making the VM instance immediately available
 
−
* Control allocation of capacity in the devices
 
  
 +
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.
  
−
Implementation or orchestration of the services (e.g., FWaaS or LBaaS) is NOT in scope of Tacker. Initial use cases are advanced network service oriented but use cases from other areas are not excluded. Indeed, folks from non-networking communities are welcomed to participate and contribute.
+

== Relation to Nova, Glance, Heat ==
+
= High-Level Architecture =
−
Tacker makes use of Nova and Glance for VM and image management.
 
−
Tacker does not, but could, make use of Heat as a subsystem to manage virtual devices.

** disable security groups: One thing that I am not sure if it has been discussed is, for L2 agent that supports security groups, such as ovs, some port filters are automatically enabled.

Tacker - OpenStack NFV Orchestration

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.

High-Level Architecture

NFV Catalog

  1. VNF Descriptors
  2. Network Services Descriptors
  3. VNF Forwarding Graph Descriptors

VNFM

  1. Basic life-cycle of VNF (create/update/delete)
  2. Enhanced platform-aware (EPA) placement of high-performance NFV workloads
  3. Health monitoring of deployed VNFs
  4. Auto Healing / Auto Scaling VNFs based on Policy
  5. Facilitate initial configuration of VNF

NFVO

  1. Templatized end-to-end Network Service deployment using decomposed VNFs
  2. VNF placement policy – ensure efficient placement of VNFs
  3. VNFs connected using an SFC - described in a VNF Forwarding Graph Descriptor
  4. VIM Resource Checks and Resource Allocation
  5. Ability to orchestrate VNFs across Multiple VIMs and Multiple Sites (POPs)
