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.

# VNFs connected using an SFC - described in a VNF Forwarding Graph Descriptor
 +
# VIM Resource Checks and Resource Allocation
 +
# Ability to orchestrate VNFs across Multiple VIMs and Multiple Sites (POPs)
  
−
The capabilities and functionality envisioned for Tacker are:
+
[[File:Tacker-Architecture.jpg]]
−
* 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, including maintenance of VM pools that can hide boot latency.
 
−
* Control allocation of capacity in the devices.<br/>
 
  
  
−
Implementation or orchestration of the services (e.g., FWaaS or LBaaS) is NOT in the scope of Tacker. Initial use cases are advanced network services oriented but use cases from other areas are not excluded. Indeed, folks from non-networking communities are welcomed to participate and contribute.

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.

Tacker - OpenStack NFV Orchestration

Tacker is an official OpenStack project building a Generic VNF Manager (VNFM) and a 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.

Use Cases

vCE

Tacker API can be used by SP's OSS / BSS or an NFV Orchestrator to deploy VNFs in SP's network to deliver agile network services for remote Customer networks

vCPE

Tacker API can be used by SP's OSS / BSS or an NFV Orchestrator to manage OpenStack enabled remote CPE devices to deploy VNFs to provide locally network services at the customer site.

vPE

Tacker API can be used by SP's OSS / BSS or an NFV Orchestrator to deploy VNFs within SP's network to virtualize existing network services into a Virtual Function.
