Assuming both cost the same. :=20 : Worst case guarantee is necessary in many cases. Easy example: :=20 : A router that can handle an STM-1 of regular Internet traffic is worthless : to us if it dies in the face of an STM-1 with minimum sized attack traffi= c. :=20 Perhaps we can generalize this by pointing out the dearth of SLA's based upon average-case. =20 Mark --=20 [] Mark 'Doc' Rogaski | Guess what?
