Re: Debian routers + firewalls for large ISP?

you have to understand that a GigaE full load will got 1.5Million packet
per second. If you want to use 10GB/sec which would be 15Million packet
per second, which is impossible to handle by ANY PC based server at all,
you could either use cluster or Cisco, dude, you have to understand WHY
people buying Cisco rather than build it on PC. Cisco use ASIC chip for
specific type of packet processing and PC just for general usage which
means it is good for everything general, but not strong on any field.
