automatic rate adaptation

but could you explain the details of the mechanism? Or is there any
reference you could point me to?
I mean, how is it handled? For example, does it count lost ACKs (after
S consecutive ACKed frames the rate is increased and after E
consecutive lost ACKs rate is lowered), does it use any timer, etc.?
Thank you again.
