  "This paper ... finds that the currently-specified DCCP variants perform less well than expected when compared to UDP and TCP. Based on an analysis of these results, the paper suggests several improvements to DCCP and experimentally validates that a prototype implementation of these modifications can significantly increase voice quality."
  "These results are due to a number of shortcomings of the currently proposed TFRC variants: miscalculation of the permitted send rate after idle periods, issues during slow-start-restart and miscalculation of the first loss interval." [All of these problems have been fixed in rfc3448bis - Sally.]
