NFV for beginners
The document provides an overview of Network Functions Virtualization (NFV), defining it as a network architecture concept that virtualizes network functions into building blocks for communication services. It discusses the competitive landscape of the telecommunications industry, detailing the need for agility and cost reduction through virtualization and standards defined by ETSI. Additionally, it highlights the role of OPNFV as a project aimed at creating a complete software stack for NFV and promoting its adoption.
