David's change only affects CCID-2, CCID-3/4 remain unaffected,
they use rfc3390_initial_rate() (which does almost the same).
 
|     I don't think this change will make sense for DCCP, once IW10 is
| for the cases of short-lived flows. DCCP is used on scenarios for
| multimedia flows, which are, in general, long-lived flows. So, IMO the
| way how we calculate IW for DCCP is appropriate, at least considering
| a quick answer. 
I agree with you, and also vote to eventually bring CCID-2 on a par with
the state of art in TCP. Before we can do this, the CCID-2 implementation
needs some work (as per separate thread with Samuel Jero).

| In fact, nowadays we need better congestion control algorithms for DCCP,

| and also we started some work to make DCCP support TCP pluggable
| mechanism , which will allow us to use TCP congestion control
| algorithms in DCCP.
This is very good news and am very much looking forward to the new approach.

| it to IW10. For the moment, I understand that for DCCP, we have to 
| discuss more about this in a separated thread.
Agree that we should keep an eye on this - perhaps too early to turn it into a
should. Networking speeds are growing, and many of the simulations were based
on TCP Reno which stems from the 10 Mbit ethernet era.
