[Iccrg] Too-big buffers in routers

[Woundy, Richard]

Also look at http://www.imconf.net/imc-2007/papers/imc137.pdf. See Figure 13 on page 10, especially the DSL and cable upstream queue length measurements.
 
I suspect there would be different results for some operators today, compared to 2007, because some operators have increased their upstream speeds (and overall upstream capacity) but with the same modem upstream queue lengths. (As one example, Comcast raised their typical upstream speed from 384k to 1 Mbps and higher in 2008.)

http://netalyzr.icsi.berkeley.edu/ tells end users about their 
buffers. Nothing stops operators from running it, too.
