Model Overview

BBS use case aims at using ONAP for the design, creation and activation of the High Speed Internet Access CFS.

Composition of services

Service	Composed Of
HSIA Edge RFS	N/A
HSIA Internet	Internet Profile VFC
HSIA Access	CPE PNF ONT-NNI CP ODN Connection Virtual Link PON-UNI CP Access Connectivity VFC OLT-NNI CP
HSIA CFS	HSIA Internet Service HSIA Access Service (with a SDC workaround to allow nested services)

Open Issues

We cannot have one VNF composed of a PNF. So the HSIA Access must be a service and not a VNF. Victor will explain how we can nest one service inside other in SDC by utilizing a known workaround.
We need to discuss if the l3-network A&AI object is the proper way of representing SDC Virtual links (ODN Connection/Transport Connection) for our use case.
We need to clarify the steps on how to find the proper Transport Connection to connect the OLT-NNI Connection Point to. Not clear.
