[nsp] From the baby to the beast

[Darren Smith]

Hi Stephen

>>> With the packets from one of the Ethernets on a Transit supplier (I've
hit well over 100kpps) I maxed out my transit router in terms of cpu \o/

> yeah but in how many unique flows, or in easier to estimate terms - how
many distinct users in each expiration interval, somewhat less than 100000
per minute...

What I meant by that was, in order to do netflow, i'll need to route my
transit traffic back via my 7401's, the CPU on the 7401's was dangerously
high last time due to the high number of packets/second, so regardless of
netflow accounting, i'll still need something a bit more beefy.

The suppliers have been trying to flog me everything from Cisco 7600's to
12416's to Juniper M160's! ;-)

Regards

Darren.
