Hi Arjuna
Clarifying question. Do you mean that the first feedback packet is sent
containing no estimate of receiver rate? Because it's sent in response to
only one packet?

Dear All,
I am in the process of updating the DCCP CCID3 ns-2 code, and would
like to know what do we do with the FIRST feedback packet. Do we
ignore it or do we increase the sending rate X by 2*X without
considering the receiver rate X_recv? Increasing it by 2*X seems to
give an aggressive behaviour.
"If (sender has been idle or data-limited)
min_rate = max(2*X_recv, W_init/R);
Else
min_rate = 2*X_recv;
If (p > 0)
Calculate X_calc using the TCP throughput equation.
X = max(min(X_calc, min_rate), s/t_mbi);
Else if (not the first feedback packet, and
not the first feedback packet after a nofeedback timer)
If (t_now - tld >= R)
X = max(min(2*X, min_rate), s/R);
tld = t_now;"
