But will it trigger at all? If the inbound rate is say 50Mbps, and the link to the in-home devices are over 100Mbps ethernet, will codel _ever_ see a 5ms buffer on inbound? Or is the shaping buffering incoming packets, and creating a bundle that it can measure? (I don't know the internals of how

No - at 90% shaping on ingress, 5/5ms will trigger when the visible queue has built up to 5ms over a continuous 50ms. At 95%, it'll trigger at 100ms. Remember, Codel can't see what's in the dumb FIFO on the upstream end of the link. By the time it triggers, there's potentially a lot of queue ther

It sounds like you are defining congestion as packets experiencing 5ms of delay over a period of 5ms. When you evaluate this, what metrics do you use to evaluate the effect on the applications using this buffer? Kathie On 5/21/15 8:26 AM, Jonathan Morton wrote: > When Codel is applied o

2015-05-21 Thread Jonathan Morton
When Codel is applied on the upstream side of a link, a burst arrives in it almost instantly, and thus it only takes 5ms to detect that 5ms of queue has developed. The interval parameter then delays action on that detection until it is certain that it's a standing queue and not simply a burst. Whe

Providing separate grades for upload and download does not make sense to me, as interference with acks in the other direction badly hurts that traffic. Uploads and downloads are *not* independent variables. KISS: one grade - Jim On Thu, May 21, 2015 at 9:45 AM, Rich Brown

That is interesting. I'm trying to think how the latency charts could be misconstrued, since a Y-axis on the right isn't the norm - I don't think it's hard to understand, but just different. The display as-is clearly shows that the download is badly bloated, but the upload is fine. That's the
