[Bloat] quality attenuation...

[Sebastian Moeller <moeller0@gmx.de>]

Just started to look at domos whitepaper for quality attenuation:
"Typically, a traffic stream of randomly-sized packets with an overall rate of 16kbps is sufficient to measure the ∆Q along a network path."
Let's see how applicable this is on a metered link:
(16*1000/8)*(60*60*24)/(1024^2) = 164.8 MB/day 
(16*1000/8)*(60*60*24*30)/(1024^2) = 4.9 GB/month

this is a lot of traffic for say anything below 10GB/month plan, no?

Yet this is still less than running a ping stream at 50Hz which comes out at roughly twice the measurement traffic volume. 

But I digress... 

Essentially for endusers the only thing reasonable/possible seems to measure the final aggregate static and variable delay/loss components... anything more involved seems to require participating friendly measurement nodes along a path that ISPs inside their own network have access to , end-users however somewhat less. 
	Just try a longer running mtr trace to your ISPs DNS servers, and note the progression of delay and loss along the path; due to rate-limiting and de-prioritization often intermediate hops show increased packet loss and delay that is not reflective to delay and loss reported by the end node. The upshot of which is these are useless for assessing "quality attenuation" for non-ICMP traffic which will not be subject to rate-limiting and de-prioritization. So with my end-user hat on, I am not sure what to do with this, as I can not verify these numbers...
