Hm.  The existing boxes which can do 100kpps can't do accounting at that
speed.  Not in the real life.

(Where have you seen a 1Mpps box which actually _works_?)

Sniffing and logging are two very different things.

1-2 _simultaneoulsy_, not over period of time.  The 1-hr matrix
would be two orders of magnitude bigger.

Anyway, it does not make any difference, as the box capable of
logging at some speed N is going to cost about the same as a
router of the same speed N (or more).  I'm not sure logging worth it.

What kind of routers?  NSSes?  You can't get that for ciscos,
sorree...
