RE: Cisco One Article

First why will be there need of fall back to traditional protocols, system
failure then Cloud computing has made it pretty rock with HA and other stuff.
With SDN i can write a script with even a CCNP level of knowledge, i can make
network work.
The question that keeps creeping up the need of ccie level of knowledge if
most of the complexity will be hidden by the software.

Thanks

I still think things will fall back on traditional protocols. What happens
when there is a failure on controller? The practices taken to to traffic
prioritization, path modification, dynamic discovery won't evaporate. You
can't ignore the potential and yes a network engineer's role will change but
it cout have a positive spin...

It seems cisco is jumping the bandwagon of SDN. But What the future hold for

CCIE candidates ? Is it time to think about moving to software side ?
