Hi Ian,
Sorry for the delay in responding.
I agree that the t_ipi implementation sketched in RFC3448 Section 4.6 is
incomplete with respect to slow applications, idle periods, and the like. :(
What follows is a first cut at a solution. Any thoughts from others??
If t_ipi is used to
I have some minor thoughts relating to this.
- In what units are t_nom kept? I would hope microseconds at least, not
milliseconds. You say dccps_xmit_timer is reset to expire in t_now + rc
milliseconds; I assume you mean that the value t_now + rc is cast to
milliseconds. Clearly high rates

Hi Gerrit,
I don't actually completely understand where you're coming from. The initial
send rate is not 1 packet per second, it is 2-4 packets per RTT, as per
RFC4342. So the initial t_ipi is going to be s/X, where X = 2-4 packets per RTT.
If you follow the logic through RFC3448 4.2-4.4,
- ccid3_hc_tx_send_packet should return a value that is measured in
MICROSECONDS not milliseconds. It also sounds like there is a
rounding error
in step 3a); it should probably return (delay + 500)/1000 at least.
This is used to set a timer to know when to wake up again which is
valid to be

WHOOPSY! I wrote t_ipi when I meant t_nominal, or whatever symbol you choose
for the time the next packet is allowed to be sent. t_ipi should not be
changed; it depends on X_inst.
