TRAM WG, draft-ietf-tram-stun-pmtud ( https://datatracker.ietf.org/doc/draft-ietf-tram-stun-pmtud/) has take a lot of time in trying to resolve the IESG comments from the IESG evaluation that occurred in September 2018. Due to the slow progress I took over the document from Spencer Dawkins as responsible AD and I did my own AD evaluation of it when there was progress in December. One aspect I wasn't particular happy with was it loose relationship to any specification on how one uses the defined probing to actually determine the working path MTU. In the meantime TSVWG has also made progress on its specification for how to perform PATH MTU discovery for datagram pacektization layers (https://datatracker.ietf.org/doc/draft-ietf-tsvwg-datagram-plpmtud/).This document is ready for IESG evaluation. After discussion with the authors I strongly believe the right way forward for the STUN PMTUD document is to define itself as a packetization layer using the TSVWG defined algorithm. On the high level this appears fairly straight forward and primarily requires clarification on how the drafts current mechanism are used for probing, and detection of black holes, etc. Due to the nature of this method of performing probing the requirements and interaction with the application UDP protocol may need a bit further clarification. I also thing the WG need to consider if all the different implementation options should remain or some simplification is need. Due to the changes in the document the above will result in I will send the document back to the WG. I don't see this as resulting in any significant additional steps as there would still be need for determining WG and IETF consensus to these changes prior to a new IESG evaluation that anyway would be needed due to the turn over of IESG members.
