I've reviewed this document as part of the transport area directorate'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 for their information and to allow them to address any issues raised. When done at the time of IETF Last Call, the authors should consider this review together with any other last-call comments they receive. Please always CC [email protected] if you reply to or forward this review.
Summary: From a transport point of view, this draft is ready for publication as a PS RFC. From a transport and congestion point of view, this draft does not change any of the underling MSRP behavior and thus this draft is the same as MSRP (RFC 4975 & RFC 4976). Details: There is one issue in the draft related to transport that, if addressed, I think would improve the draft. Consider the case of a chat room that is receiving messages at a rate of 10 per second (perhaps bad-attitude during the IESG plenary) and also has some clients in the chat room that can only receiving messages at a maximum rate of 5 per second ( perhaps an iphone via VPN over 2G). Section 6.1 does not say what should happen in this case.
