We shouldn't assume only Reno, but as EKR pointed out, the text should describe something we expect to perform reasonably well. Yes, let's keep ack delay is a separate issue. And I completely agree that we don't want to specify only acking every two packets. If we specify ack ratio, I tend to think it should be in bytes, not packets, but possibly it doesn't really matter? However, it seems like min number of acks per RTT is just as valuable as max number of bytes received before sending an acknowledgement. At the moment, I'm fairly concerned that we are only aware of one congestion controller that deals well with intentional receiver-side aggregation/decimation, and it is ok with any value of ack_ratio. More important to BBR is getting somewhat regular feedback, ie: at least once per RTT, ideally more often. -- You are receiving this because you are subscribed to this thread.
