The document discusses the implementation of virtual customer premises equipment (vCPE) using OpenStack, OpenDaylight, and service function chaining (SFC) to enhance cloud infrastructure management and orchestration. It highlights the role of Tacker as a management tool for virtual network functions (VNFs) and outlines advantages such as simplified operations, reduced vendor lock-in, and dynamic service insertion capabilities. Key technologies mentioned include NFV management, SDN performance, and hyper-converged infrastructure.

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.
