Am I the only person who has heard of Google?

It didn't take me long to find this wiki page
http://www.bro-ids.org/wiki/index.php/ClusterFrontends
for an Opensource Intrusion Detection System that lists
various 10G cards for Linux and a couple of FPGA cards
so that you can roll your own ASICs. Anyway, this one
http://www.lewiz.com/talon3220.html
has two ports and claims to reach 8.8 Gbps with 1500 byte
packets.

People rolling their own router are not the only ones who
want to do 10G on Linux.

Anyone who wants to roll your own more advanced apps on Linux without reinventing the wheel may want to check out my friend's company:

http://www.bivio.net/products/bivio7000.htm

Even with their specialized hardware platform, bus, and extensive tuning, they only get 10Gb/s throughput on the dual or quad 10G modules. However you can do 100,000 line ACLs at that speed. It is built for a different application than core routing. However, an XMR or Sup720 will still be a lot cheaper and give better performance.
