Hi I believe that it is beneficial to use a 1:10 policy, I understand that this means that a 1:2 policy that still be used in the initial phase (flow start) or does the timer mechanisms kick in to avoid that ACKs are transmitted too sparsely in this case ?. /Ingemar From: Gorry Fairhurst <notifications@github.com> Sent: den 28 april 2020 13:38 To: quicwg/base-drafts <base-drafts@noreply.github.com> Cc: Ingemar Johansson S <ingemar.s.johansson@ericsson.com>; Comment <comment@noreply.github.com> Subject: Re: [quicwg/base-drafts] Changing the Default QUIC ACK Policy (#3529) On 27/04/2020 17:19, Lars Eggert wrote: > Folks who care about a change here need to prioritize progressing this > issue.

Our hope is that this change to the spec, to actually make standard end-to-end QUIC work better than TCP over asymmetric paths! This is a short slide deck about the performance of the proposed change: https://erg.abdn.ac.uk/users/gorry/ietf/QUIC/QUIC-ack10-24-april-00.pdf There have been a number of other change made by the QUIC ID editors relating to ACK processing, so we wanted to be sure these results were up to date. (These results do not consider additional ACKs after re-ordering - reflecting the latest text removing that.) We also really hope this will motivate a change the practice of forcing of QUIC fallback to TCP (with PEP/Thining) over highly asymmetric paths. People may also be interested in work for L4S to evaluate the impact of ACK Thining for TCP-Prague. Please do provide feedback, or any questions on this - as Lars notes, we think the time is running out for considering new changes, even relatively simple ones like this. Gorry P.S.
