a simple search on google, I find a paper about a routing table lookup algorithm, on standard CPU, able to do 30Millions lookup per second (on a 500MHz cpu). with current CPU frequency, it would rather be 120Millions/s on such "commodity pc" the bottleneck is the bus architecture, though. 2Gbit/s of traffic translate to roughly 400000 packets per second that leaves a lot of spare cpu time. -- Philippe Strauss av. de Beaulieu 25 1004 Lausanne http://philou.ch/ _______________________________________________ swinog mailing list swinog@lists.swinog.ch http://lists.swinog.ch/cgi-bin/mailman/listinfo/swinog
