What if the edge router is sitting at MaeEast or some other very busy edge of your network. Knowing traffic patterns to/from the interconnects is very useful for traffic engineering and neccesary if the "attack" you want to trace back goes through an interconnect. I may be wrong, but I was under the impression that flow switching wasn't up for this and regular IP accounting is completely useless in this particular case. Curtis - - - - - - - - - - - - - - - - -
