[AusNOG] back of envelope sizing calculations

[Skeeve Stevens]

Actually, I have multiple 3845's running 3-4 full world tables and doing it without any sweat.  It has also been discussed on NANOG as a fine solution.

Not dissing Juniper, they seem like great hardware... but if you're a Cisco house... don't go introducing new platforms for amusement sake.
