Reviewer: Linda Dunbar Review result: Ready Hi, 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. Reviewer: Linda Dunbar Review result: Almost Ready, with comments During my review period, the authors have updated the drafts twice, which have addressed many of my previous comments well. Only one more comment: Can you provide some sample "Applications" that actually do differently depending on the Host OS' Transport capability? All the "Applications" I know of usually finalize on which Transport Protocols to use and which transport layer capability is necessary and can only be placed on the Host OS that meet the requirement. Thank you. Linda Dunbar
