We need to be careful with the word “transport”. In some contexts it refers to pure transport technologies (e.g. OTN, WDM) and does not include other upper layer TE technologies (e.g. MPLS-TE and SR-TE), in other contexts it includes also the latter.
I’m more than happy to use the term transport SDN controller provided we’re all on the same page (which should be the second).

Subject: [Teas] "Hierarchical T-SDN Controller"

In the (useful) I-D draft-bryskin-te-topo-and-tunnel-modeling-00, Section 1.9. “Multi-Domain Transport Service Coordination” uses the following wording:

   A client of multiple TE network domains may need to
   orchestrate/coordinate its transport service setup/manipulation
   across some or all the domains. One example of such a client is a
   Hierarchical T-SDN Controller, HC, managing a connected multi-domain
   transport network where each of the domains is controlled by a
   separate Domain T-SDN Controller, DC.

Outside the IETF, I have the impression that this terminology is quite common when discussing TEAS YANG models. I wonder whether we could use this terminology more frequently inside in TEAS.
