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.
Hi Sargun, SRAM != TCAM. With SRAM you can only access one word per cycle. The coolness of the TCAM is that the entire memory is queried in one cycle, spitting out the best match. Nevertheless, there is some interesting hardware out there. The Endace DAG card with the coprocessor has a TCAM on it, but it's not big enough to handle a full BGP table.
