I'll chime in,

In an enterprise environment, I've worked with software routers as well as
hardware beasts (ala Junipers, Cisco 6500s, ASAs, and more).

Ultimately, the network is as reliable as you build it. With software, it's
much cheaper to divide and scale horizontally. Hardware devices are
expensive and usually horizontal scalability never happens. So in reality,
an enterprise blows 100k on two routers, they both flop because of some
"firmware bug", and you're down.

The most reliable/cost effective solution is the cheap and redundant
approach to architecture.

Reliable hardware is incredibly inexpensive, and every year we get better
CPUs and (recently) GPUs that are providing APIs and interfaces to their
incredible parallel processing capability.

btw, you guys might find
PacketShader<http://shader.kaist.edu/packetshader/>a pretty
interesting concept
