Hi,
DCCP is a new transport protocol, like TCP and UDP, RFC 4340. For
ekiga, as a streaming video application, it should be better from
several points of view:
- it has congestion control, unlike UDP
- the packet retransmission is not mandatory, as TCP
- it has acks from receiver to sender

Hello Eugen Dedu,
yes I think that will be way VoIP will evolved. It not a question
whether but when.
As we are planing this implementation for a research project, we need
to be a bit ahead of the line.
Lets work together on this issues? I am actually not sure where to add it ;-)

"...Problem Statement for [DCCP]", which discusses such questions as
"why not just implement congestion control at the application layer?"
This is because it is not so simple

inside IPv4. Second, this is a temporary solution, I saw 1-2 months ago
(I lost the link) that NAT on linux (masquerading) added support for DCCP.
Found it: http://lwn.net/Articles/278495/, look for DCCP string.

Ekiga-
I'm currently working on a TFRC integration to obtain a video rate control
that is adaptive to the network conditions (e.g. congestion state). Up til
now, I were using RTCP receiver reports (RR) and sender reports (SR) to
calculate the following parameters:
at the sender:
- localRTT = ReceiverRep
