Heavy Reading 2014 December http://contextream.com/media/docs/HR-ConteXtream-Fit-VNF-WP-12-8.pdf The important Factors Driving NFV deployment is Service Agility & Flexibility In a virtual environment, where applications are extracted from hardware, VNF de- signers face different challenges and opportunities. If operators are to achieve a step change in service agility, it should be possible to provision VNFs on a quasi-on- demand basis. Fit VNFs can be dedicated to a single function and then connected together using traffic steering (or “chaining”) mechanisms to create services.
