have all been unique like snowflakes and required expensive custom
integration, whereas VNF products and services should be designed for
easier integration just like Lego\ :sup:`TM` blocks. For example, by

**Network Cloud Service Providers (NCSPs)**
Other parties such as solution providers, open source community,
industry standard bodies, students and researchers of network
technologies, as well as enterprise customers may also be interested in
-the VNF/PNF Guidelines. Solution Providers focused on specific industry
-verticals may find these VNF/PNF guidelines useful in the development of
