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.
