This does not pertain to linux-kernel in any way: Ascend has announced
the "GRF 400", an IP "switch" (huh? what? an IP switch?). It
promises hardware assisted route table lookups and traffic across all
interfaces at "wire speed". The specs mention that is can handle
150,000 routes.

For those of us that are bandwidth-hungry....this is definitely a
"woodening" article.


And since this is my first message to the list, I should say: Thanks
Linus!
