As part of the VNF SDK project, VNF modeling subproject has been focusing on establishing a consistent end-to-end approach for VNF and VNF package modeling in R2. We have identified several starting point for standardization of these models. What we need to do next is to agree on what models and/or standards are going to be applicable at what stages of the VNF lifecycle. We will start with the VNF model, as it is seen by VNF developers, inclusive of compute/storage/network hardware requirements, telemetry and policy specification, and identified how this information is ingested and trasformed into other models as part as part of VNF on-boarding (SDC), instantiation (SO/VF-C/Optimization/Policy) and operation (APPC/VFC/Optimization/Policy). We will also need to understand how policies and telemetry apply across the VNF management lifecycle, at what point they are defined, who gets to define them and how they are blended/federated with policies already provided during VNF on-boarding.
