Hi Rodney, Some supplementation and modification: Ietf-detnet-topology in the document is used for ' device and link capabilities (feature support) and resources (e.g. buffers, bandwidth) ' discovery, so it is the southbound interface. However, it is not part of DetNet flow configuration, and so we think maybe it can be an independent work.
