Hi,
In my opinion OpenFlow is a great protocol, for the moment still in
evolution, born for campus LAN environments.
For the moment I wouldn't use (but maybe it's just for my current
abilities) OpenFlow for all my production environment.
I see OpenFlow as a first step of a long way of the SDN paradigm. Many
producers currently presents OpenFlow as their key, others consider it a
small part of their technology, introducing their own SDN APIs and
protocols, maybe better performing but locking you in another time.
Anyway consider that OpenFlow currently works perfectly (as far as I
know..) in both big campus networks and test-bed in US (and probably not
only).
Now it's up to you ;)
Cheers,
Luca P.

Hi,
i read several articles on OpenFlow and like the concept behind it.
I run a small network at a school with 300 devices. Currently we use
10 years+ old dumb switches. At that time there were very few
notebooks and no smart phones or user provided/private devices. It now
becomes important for me to separate networks and secure some parts of
the network. To achive that, i have to replace most of the switches
(roughly 30, mostly 24 ports) anyway. I could simply use radius and
accoringly relativly cheap switches or i could use "layer 3 switches"
and maybe manage the network traffic using OpenFlow. Those switches
are quite expensive it seems, starting from 1500 euros for 24 Ports,
as far as i can see. I have one Cisco sg 300-28. The idea of having to
manage 20 of these type doesn't please me. I find that centralized
view provided by OpenFlow's controller quite appealing.
Anyway, as you might have guessed, i'm far from being a network
wizard. Is OpenFlow a path i could go (after spending some time on
further researches, of course) or just an overkill?
Any comments are appreciated.
sincerely
Malte Müller
