|
| Network Function Virtualization (NFV) continues to draw immense attention from researchers in both industry and academia. By decoupling Network Functions (NFs) from the physical equipment on which they run, NFV promises to reduce Capital Expenses (CAPEX) and Operating Expenses (OPEX), make networks more scalable and flexible, and lead to increased service agility. However, despite the unprecedented interest it has gained, there are still obstacles that must be overcome before NFV can advance to reality in industrial deployments, let alone delivering on the anticipated gains. While doing so, important challenges associated with network and function Management and Orchestration (MANO) need to be addressed. In this article, we introduce NFV and give an overview of the MANO framework that has been proposed by the European Telecommunications Standards Institute (ETSI). We then present representative projects and vendor products that focus on MANO, and discuss their features and relationship with the framework. Finally, we identify open MANO challenges as well as opportunities for future research. |
