Network Functions Virtualization (NFV) is a networking paradigm that decouples network functions from proprietary hardware by using virtualization technology. Although originally conceived to reduce OPEX and CAPEX (operational e capital expenditure), NFV is today much more about flexibility and short innovation cycles in computer networks. NFV is said to be the enabler of an opener computer network market because it allows small players to compete when delivering innovative network functions running on top of off-the-shelf hardware. As in most new technologies, NFV enables opportunities of business that were not possible before its inception, but it also introduces new problems that were not present before. In this talk, we will observe NFV from two different yet complementary perspectives: NFV as a network management tool, as well as NFV as the target of the network management process. We will review which management activities are better/easier/faster performed in networks that support NFV, and we will also observe which management challenges are imposed by NFV into traditional management solutions and networks. The market and research state-of-the-art will be reviewed in the area, and a list of today’s further required research and development work will be discussed as well.
