[CCAMP] draft-ietf-ccamp-client-signal-yang references to bandwidth profiles, make it a leafref

["Roque Gagliano (rogaglia)" <[e-mail]>]

Hi,

I implemented the draft and I think the bandwidth-profile should be a leaf-ref and not a string (for both directions symmetrical and asymmetrical):

          |  +--rw (direction)?
          |  |  +--:(symmetrical)
          |  |  |  +--rw ingress-egress-bandwidth-profile
          |  |  |     +--rw (style)?
          |  |  |        +--:(named)
          |  |  |        |  +--rw bandwidth-profile-name?
          |  |  |        |          string                   • We need a leafref to the definition of the bandwidth-profile
          |  |  |        +--:(value)

In particular, I believe it should be:
type leafref {

                   path "/ethtsvc:etht-svc/ethtsvc:globals/ethtsvc:named-bandwidth-profiles/ethtsvc:bandwidth-profile-name";
               }

Why is this important? As an implementor, I need to understand the relationship between these nodes in order to select the right order of RESTCONF commands.

If the leafref is not present, I would assume that the nodes are not related and I could try to delete a “named-bandwidth-profile” that is actually used in a service. Also, when I am trying to delete both a “named-bandwidth profile” and all its associated services, I would need to delete the service first and the profile later (when there Is not instance that reference it).

For all of this to happen, as both nodes belong to different trees, I need to reference them to make the association explicit for a compiler.
