Little you two know about SDN, please read the following presentation from Scott Shenker and then get back here arguing what it is and what it is not: https://inst.eecs.berkeley.edu/~cs168/fa14/lectures/lec23-public.pdf
I'll pass, thanks. Already did my time in that rabbit hole.
Yeah. Also, I see great piece near end of the slide deck: "We (Berkeley) are pushing SDNv2 which focuses on - General processing at the edge (middleboxes) - Very simple processing in the core - Support for third-party services (using mboxes)” I believe I’ve seen this somewhere ;) Are we reinventing tag switching? Mind it, PDF is from 2014 and represents very naive approach to SDN (sorry, “SDNv2”). And yes (to the main topic of this thread) - I have some certs. I understand people without certs tend to discard them as non-relevant or even toxic. Yes, I’ve met “paper” CCIEs, but also JNCIEs and I can see the point being made. I’ve met great minds (also on this list) without any networking certificates. I believe that until you see real person on the other side of table and not her/his cert(s), good chat and questions will remove all doubts. Everyone has to start somewhere and make those first errors, and being ‘expert’ doesn’t mean you’re not making them anymore. -- Łukasz Bromirski CCIE R&S/SP #15929, CCDE #2012::17, PGP Key ID: 0xFD077F6A
