Ask HN: What happened to Bufferbloat?
A few years ago I heard a lot of people worrying about how large buffers in our routers would cause latency problems. It all sounded very serious---like the end of the Internet. But I haven't heard any news for a couple years. Everything on the Wikipedia page looks old:
https://en.wikipedia.org/wiki/Bufferbloat
Is this something people are still concerned about? Were the original reports just hyperbole?
- mmagin 11y agoIt didn't go away. I was reminded of it recently when I read this: https://www.febo.com/pipermail/time-nuts/2015-July/092770.html https://www.febo.com/pipermail/time-nuts/2015-July/092770.ht...
- MaulingMonkey 11y agoTwitch working on a form of buffer bloat recently: http://blog.twitch.tv/2015/05/new-reduced-stream-delay-beta/ http://blog.twitch.tv/2015/05/new-reduced-stream-delay-beta/
- MaulingMonkey 11y ago(For clarity, not router buffer bloat, and there's no real technical discussion there either.)
- vezzy-fnord 11y agoSeems like it's a phenomenon that goes through cycles of visibility, given its documentation dates back to the early 80s.
- drv 11y agoThe bufferbloat-related changes made in CeroWRT (http://www.bufferbloat.net/projects/cerowrt http://www.bufferbloat.net/projects/cerowrt) have been merged into the Linux kernel and the OpenWrt project.
- dtaht 11y agoIt is everywhere... pretty thoroughly quantified now (example: http://www.dslreports.com/speedtest/results/bufferbloat?up=1 http://www.dslreports.com/speedtest/results/bufferbloat?up=1 ) It is serious and remains so... but Fixes have emerged (fq_codel, pie, cake) that are widely available in linux and linux derived gear - which had spectacular results: http://burntchrome.blogspot.fr/2014/05/fixing-bufferbloat-on-comcasts-blast.html http://burntchrome.blogspot.fr/2014/05/fixing-bufferbloat-on... and pie was mandated as part of the docsis 3.1 std. and standardization efforts of the new aqms is taking place at the ietf. For example, this RFC just emerged: https://tools.ietf.org/html/rfc7567 https://tools.ietf.org/html/rfc7567 and there are other products of that working group nearing finalization. While wifi and lte remain to be fixed, I sleep better knowing that the tide is turning.
