That's my point.  The answer is to get rid of the concept of an
RSP completely.  A box with a central CPU is never going to scale as well
as a distributed processor design no matter how many MHz you throw at it.

There ARE vendors that have such designs (and have had such designs for about
the past 5 years or so..)

While admittedly I (strongly) dislike Cisco, it is in the best interest of the
entire Internet to see them build a better box.  With 80% of the routers
in the Internet being Cisco, these types of DoS attacks make me a bit
nervous about our future when the infrastructure is built on what
is IMHO a non-scalable architecture.
