Model Overview


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

(with a SDC workaround to allow nested services)

Open Issues

  1. 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.
  2. 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.
  3. We need to clarify the steps on how to find the proper Transport Connection to connect the OLT-NNI Connection Point to. Not clear.

  • CP derived from tosca.nodes.nfv.vduCp
  • Connectivity will reuse tosca.nodes.nfv.VnfVirtualLink
  • To be edited, the requirements for virutal_binding depends on how to model the BNG itself.
