    Where is ONAP in the picture?

    In Flow 6: Service Subscription To Profile Flow

    This looks to be the actual service flow for an access network service - Something that would come from a HSIA product with parameters for the UNI and NNI of the POD along with some service information like the VLAN or priority tags for the UNI and NNI. - Am I missing something?

  3. Cem Türker

    Tim, you are right. We should probably merge 4th and 6th flows. I will take a look.
