There's also the 7304 which, bundled with a
NSE-100, is quite a little beast. Features
hardware forwarding (unlike the NPE-G1 based
7206VXR/7301) for most things. So it's somewhere
between vxr and 7600.

A NPE-G1 can not handle a DoS attack at wire-speed
gigg. The 7304 can keep with a gigg at minsize
packets. You can add more interfaces though but
you won't be able to run them at wire-speed.
