This document has been reviewed as part of the transport area review team's ongoing effort to review key IETF documents. These comments were written primarily for the transport area directors, but are copied to the document's authors and WG to allow them to address any issues raised and also to the IETF discussion list for information. When done at the time of IETF Last Call, the authors should consider this review as part of the last-call comments they receive. Please always CC tsv-art@ietf.org if you reply to or forward this review. I think the draft is well written and informative. I haven't found any transport related issues in the document. I think the draft is ready for publication. One minor comment I have in the draft is if we can safely assume there is no packet reorder in this architecture. I think it would be better to mention it in the document. Thanks, -- Yoshi
