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.
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. 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. > >>> >> _______________________________________________ >> Bloat mailing list >> Bloat@lists.bufferbloat.net >> https://lists.bufferbloat.net/listinfo/bloat >> >> _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat >
