3'nd.. Do you mean VIP2 idea is worst then SSE idea?
The VIP2 is a fine idea. However, it's again using conventional
microprocessor technology for forwarding. And unfortunately, it needs to
be fairly high end processor technology to sustain the rates. The problem
is that the traffic demand far exceeds the growth rate of processor
forwarding.
So the problem is that as we approach higher speed (post-7500) interfaces,
you're forced into more specialized hardware. At this point, not having an
SSE ASIC becomes somewhat silly. The rest of the board is ASICs, which in
volume end up cheaper than processors...
