   other direction.  To me, saying that a line is being utilized at 100%
   of capacity means that no more traffic will fit.  That is not the
   case when one bases such utilization numbers on just the larger of
   the IN/OUT traffic.  This may not be the most mathematical approach
   to this problem, but most users (and bosses) don't care about technically
   correct statistics - they want numbers that make sense, and that give
   a real measure of how much of what they're paying for is actually
   getting used.

I agree with you that most users want numbers that "make sense."
However, "making sense" is what is being suggested.  A line
utilization of 100% in one direction and 0% the other is "technically"
only 50%.  However, that user is probably screaming (well, asking at
least) for more bandwidth and is not interested in hearing that the
link is only used 50%....

Actually, I always treat the two directions of a serial link
separately and calculate separate utilizations.  (Of course, they have
to be upgraded at the same time (:-).)  It is often useful to look for
substantial asymmetries, as they provide clues as to what is going on
in the net.
