Aw.  A sign of neophyte.  If Cisco sells something it doesn't mean
it makes any sense.  Where Cisco (Con)Fusion went?  And, yeah, the
wonderful clustering solution to the eternal not-enough-speed-
and-not-enough-ports screams from ISPs.

Did anyone actually try to collect detailed billing-ready information
on customer traffic flows on any decent size backbone?

Oh, well.  That kind of traffic analysis can make sense in corporate
networks (though fast LANs are _cheap_).  Few people really understand
how huge the Internet is.  So huge, in fact, that anything requiring
more than O(log N) operations to compute is not feasible on a daily
basis
(where N is the number of end-hosts).

And yes, Internet is growing faster than box performance -- so things
which are not feasible now aren't going to be feasible tomorrow.  Quite
opposite, if anything.  How about collecting billing records at a
terabit
per second?  That kind of speed is demonstrably doable with today's
technology.
