There is a company called Netduma which sells a product called the Netduma R1 Router. It's main feature is reducing lag. It does this through QOS and GEO-IP Filtering. (Limiting available servers to your local region = reduced RTT)<br>
<br>
It seems relatively popular in the gaming world, especially console.<br>
<br>
It is based on OpenWRT Chaos Calmer: <a href="https://netduma.com/opensource/" rel="noreferrer" target="_blank">https://netduma.com/opensource<wbr>/</a><br>
<br>
It has an advanced QOS system that already uses FQ_Codel.<br>
<br>
Here are the hardware specs:<br>

<br>
I assume it has an ath9k.<br>
<br>
Maybe they could implement the ath9k fq_codel and airtime patches.<br>
<br>
The user base that buys this product seems like they would be more familiar with setting up routers than the average person.<br>

If there is a simple affordable solution, say Open/DD-WRT distro based bridge that all you do is configure your up/down bandwidth and it applies Codel/fq-Codel/Cake, then all you need to do is drive up awareness. A good channel for awareness would be getting in contact with popular Twitch or YouTube gaming streamers. But I wouldn't put much effort into driving up awareness until there is a device that people can easily acquire, use, and afford. At first I was thinking of telling people to use *-WRT supporting routers, but changing the firmware on your router requires too much research, and many people care about bleeding edge features. You need something that works in tangent with whatever they are using.<br>

If Comcast sells you 100/20 (I have no idea if this is a thing), you set your upstream on this box to 18 meg fq_codel, and then Comcast oversubscribes you so you only get 15 meg up part of the time, then you're still bloated by the modem. This is not a solution.<br>

I don't think "buy $thing, install *WRT on it, configure it like this" is above most gamers, but I'm afraid we don't even have a working solution for someone with that kind of skillset.<br></blockquote></blockquote></div></div></blockquote><div><br></div><div>I would be curious to know what the 80/20 rule is. Can we reach it with what I described? The other way to handle the situation you mentioned is to tell the end users they can trade more bandwidth for a less likely chance of having high latency, depending on the stability of their ISP.</div><div><br></div><div>There is also the strange issue of crazy high bursts from video streaming services. I know Netflix is working on the packet-pacing problem with FreeBSD, but I've done packet-dumps from several streaming providers and the issue seems to be with TCP with transient activity and data transfers that with in the TCP transmit window. A 5Mb/s average really turns into a 40Gb/s burst of 256KiB of data 3 times a second. Since the buffers are large, they don't drop anything. The bigger issue is the end-user sees an "average" ping that is low, but they get constant transient oddities while gaming and can't figure out why someone streaming 5Mb/s is hosing their 100Mb connection.</div><div><br></div><div>Most people only have a 1Gb network link, so a 40Gb burst won't get through anyway, but they will see a 1Gb burst dragged out 40x longer, giving a bridging device time to drop a packet or two and signal TCP to back-off. Looking at my WAN port, I actually see back-to-back packets at 1Gb line-rate from Netflix, Hulu, Youtube, and Twitch for long lived connections that have periodic activity.</div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="gmail-HOEnZb"><div class="gmail-h5"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
