Summary:




This draft is ready to be published as Standards Track RFC but I have some comments.




 




Major issues:




 




 




Minor issues:




 




 




Nits/editorial comments:




-[Page 4], "Equal treatment of media" section. 




While reading this paragraph the question comes to mind of if all media flows get 'best effort' only or if all media flows could get e.g. 'Gold treatment', or something in between...




It would be clearer to add a sentence to say how the treatment (QoS) is specified and applied to all flows.




 




-[Page 7], "This specifications purpose"----->"This specification's purpose"




 




-[Page 8], "It is important to note that the RTP payload type is never used to distinguish media streams."




It would be clearer to add this would be explained below. "As expalined below, ..."




 




-[Page 9], "form a independent"--->"form an independent"




 




-[Page 11], "that FEC stream use"---->"that FEC stream uses"




 




-[Page 11, 




"(e.g., if an original RTP




   session contains audio and video flows, for the associated FEC RTP




   session where to use the "audio/ulpfec" and "video/ulpfec" payload




   formats)




"




 




This sentence may need revision, word "where" to be revised.




 




-[Page 11], "with a associated generic"---->"with an associated generic"




 




-[Page 11], ULP (uneven level protection) to spell out.




 




-[Page 12], "this requires each media type use" -----> "this requires each media type to use"





 




-[Page 14], some references are expired. Should they remain cited?
