I think the biggest problem is differentiating between bloat on the ISP side and bloat on the endpoint router. A given ISP may have very good internal setups, but bad/obsolete equipment at the endpoints, or the endpoints could be upgraded and the ISP could still have problems on their side. > Call B the "blue" series of latencies. > Call G the "idle" series > Call O the "orange" series > > What is fn1(fn2(B),fn2(G),fn2(O)) that generates an open-ended bloat > factor, where 0 is no problem ? > What is fn1() that takes a series of latencies and produces one latency? > What is fn1() that takes three latencies, and produces a bloat factor? > > And then having obtained a "bloat factor" for one result, do you combine > them using an average? > > Also should there be another input such as connection speed. > Should higher speed lines be held to a higher standard? if you measure the bloat as the difference from idle, then using one standard for all speeds should be reasonable. > The "bloat factor" can be what is reported next to Ping on a test result. > Should it be an infinite set of numbers from 0 .. infinity or should it be > a grade > A+ down to F ? > (a grade would be more user-friendly). I think A+ down to F is good. based on our jitter discussion, A+ <5ms A <30ms B <60ms C <200ms D <400ms F >400ms or something like this (so that not all situations result in A+ or F) David Lang > On Wed, Apr 29, 2015 at 12:48 AM, Dave Taht wrote: > >> https://plus.google.com/u/0/107942175615993706558/posts/ZytYb4ZkMdY >> >> -- >> Dave Täht >> Open Networking needs **Open Source Hardware** >> >> https://plus.google.com/u/0/+EricRaymond/posts/JqxCe2pFr67 >> _______________________________________________ >> Bloat mailing list >> Bloat@lists.bufferbloat.net >> https://lists.bufferbloat.net/listinfo/bloat >> > --===============0887834287323507417== Content-Type: TEXT/PLAIN; CHARSET=us-ascii Content-ID: Content-Description: Content-Disposition: INLINE _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat --===============0887834287323507417==--
