I have reviewed this document as part of the Operational directorate’s ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. Document reviewed: draft-ietf-clue-protocol-17 Summary: The CLUE protocol is an application protocol conceived for the description and negotiation of a telepresence session. The design of the CLUE protocol takes into account the requirements and the framework defined within the IETF CLUE working group. A companion document delves into CLUE signaling details, as well as on the SIP/SDP session establishment phase. CLUE messages flow over the CLUE data channel, based on reliable and ordered SCTP over DTLS transport. Message details, together with the behavior of CLUE Participants acting as Media Providers and/or Media Consumers, are herein discussed. I think the document make sense and is written very clear, except some small nits: # The XML examples seem not compatible with XML format, especially, the folding lines. For example: Suggest to following the artwork folding rules [draft-ietf-netmod-artwork-folding-00]. # A run of idnits revealed there were 0 error, 4 warning and 2 comments: Miscellaneous warnings: ---------------------------------------------------------------------------- -- The document date (September 21, 2018) is 58 days in the past.
