If the tool were to list ISPs in descending order of a bloaty factor from
best (like this
one) http://www.dslreports.com/speedtest/375736
to worst (like I don't know yet), what would be the ranking factor?
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)
