Dear WG Chairs, Authors, I think I need to clarify my view regarding the WG adoption of this draft. I share concerns expressed by Tarek. Also, it is not clear the role of resource-SID in the case of FlexE underlay. And it does appear that an SR node will maintain state per resource-SID it is provisioned by the controller. That, in my opinion, breaks the SR paradigm of no per-flow state at intermediate SR nodes. I believe that any solution to the problem of SR-TE should be weighted against the work on Transport Slicing at the TEAS WG.
