In enterprise and data center there is also very good control over
what equipment is used and how it is used.  However, clue density
decreases exponentially farther from the core and approaches zero in
some data centers and in some enterprise IT departments.  This is also
true of the part of service provider organizations that pick stuff for
consumer access.  Where clue density is lowest, you'll find ignorance
of AQM and buffer issues and lack of consideration for buffering and
AQM when picking equipment for deployment and configuring it.
