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 - 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.

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.
