In regards to min(ack_delay, max_ack_delay), it's critical to consider what srtt is used for, which is loss detection and timers(TLP and RTO). If there is a high rate of ACK loss or if the peer's alarms are persistently waking up late, then the SRTT and/or RTTVar will increase, thereby increasing these timers. If this happens very infrequently, then the EWMA will forget them relatively quickly. I think that seems appropriate? To think of the pathological case, what if a peer communicates a max_ack_delay of 0? I think it's important the rest of the recovery machinery still functions correctly in that case. -- You are receiving this because you are subscribed to this thread.
