The document discusses the drivers for software-defined networking (SDN) and network function virtualization (NFV) deployment from a service provider's perspective. It covers key enablers like OpenStack and the ETSI NFV architectural framework. Several use cases are presented, including virtual managed services and a virtual carrier WiFi core. Challenges of SDN/NFV deployment are also examined. Essential skills for next-generation network engineers are identified, such as Python, XML/JSON, container virtualization, and Linux skills.
