The present document defines a framework for use within ETSI NFV ISG to coordinate and promote public demonstrations of Proofs of Concept (PoC) illustrating key aspects of NFV. The objective for the PoCs is to build commercial awareness and confidence and encourage development of an open ecosystem by integrating components from different players. This framework outlines: rationale for NFV ISG PoCs; NFV ISG PoC process; format and criteria for NFV ISG PoC Proposals; NFV ISG PoC Report format and requirements.
