1. Deployment Flavour as VNF Capability: Alt1_r3
May 31, 2017
Thinh Nguyenphu, Nokia
History:
R1: based on each DF (different topology) would be represented in its own Service Template. And, All the common attributes of VNFD should be described in as properties within VNFD capability type.
R2: update slide 7
R3: including examples
