The Xilinx Virtex family can already do 10G, if you
are into FPGA development (I seem to recall the
first Xilinx FPGA that could do 10G was 4-5 years
ago; forever in Mo

FPGAs can be used to do both SRAM and TCAMs. All that is needed

I wonder how difficult it would be to integrate such a device on to
an x86 board cheaply. Something like NetFPGA (http://netfpga.org/) would
be an interesting place to start. The board has on board SRAM, a bit of
DRAM, an FPGA, and 2 GigE interfaces.
I know it definitely isn't normal for

Correct
Actually, soon this will no longer be true. Vyatta's new platform,
Glendale, will be moving to Quagga. Quagga is much more stable, and
slow-moving compared to Xorp, which makes me slightly more comfortable
(less breakage between versions). There are some major features lacking
inside of the platf
Actually the latest version of Vyatta uses Quagga. If anyone is
interested in discussing the differences in running the two in
production networks feel free to contact me off list.
In full disclosure, I work for Vyatta.
Cheers,
Robert.
