No, Cisco uses QNX to run actual routing algorithms, don't believe me
if you want, frankly I don't give a damn.

I have friends who work at Cisco and actually had to write code for
the routers, their big complaint was that QNX does not have dynamic
memory allocation mechanisms. (You can not do dynamic memory in hard
real time, which is why RT threads in Java are such a big joke.)

Maybe Cisco does not mention QNX because they don't want to confuse
people, maybe they want everyone to think they make routers, switches
and operating systems. I don't know. I just know how it works, not
why marketing departments think the way they do.

No Cisco is not considering, they have been using QNX for years -
don't trust what you read on the Internet, actually find someone who
is implementing EIGRP or something at Cisco and ask what OS they are
coding for.

The course has been around since the mid 70's its not going anywhere
anytime soon.
