Datagram Congestion Control Protocol (DCCP)
DCCP Web Pages:
Vlad Balan, Lars Eggert, Saverio Niccolini and Marcus Brunner,
An Experimental Evaluation of Voice Quality over the Datagram Congestion
Infocom, May 2007.
"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
