Hi,
The vision of the vendor depends of course vendor by vendor. As I told
you beforse, for example brocade sponsors OF as the new real protocol to
use, as well in the production environment. Anyway you understood
correct: this is what vendors says generally...
The idea could be having a "piece of iron" doing what you want, a
commodity hardware that can become a switch, a firewall, a router,
everything....Of course, as exactly happens in computing you must have
dedicated hardware for special purpose tasks.

Hey Luca,
Many thanks for your reply! If i understand it correctly; the vendors
do support OpenFlow, but are not willing to adopt it completely. They
support it as a plugin or as some fancy function. They are (for
obvious business reasons) playing it off as a "researchers" thing,
not suited for production networks. Correct? So Merchant Silicon in
that sense gives us, the networking field, a device which is "open"
and thus the full potential of OpenFlow can be implemented as how we
see fit (without vendors telling us what we can and cannot do)?
Thanks again and kind regards,
Farhad.

Hi Farhad,
About what I've heard from vendors they generally support OpenFlow
just as a plugin of their systems. This is not true, for example,
for Brocade that belives in OpenFlow making of it their new key
feature functionality.
What I generaly see from companies like CISCO or Juniper is that
they say: ok, OF is a good protocol for research and we support it
as a plugin in our systems, but we've been working on networks for
years, thus we can do everything better. Morover, they distribute
part of the intelligence locally on the devices, that actually
don't cost less than a "common" device. Most of the times SDN
support is given in the device OS as a new (sometimes) optional
features and for this, most of the times, you could pay the device
also more!
Cheers,
Luca

Hey folks,
Perhaps a silly question: I am kinda confused because i was
thinking that OpenFlow wouldn't be possible without Merchant
Silicon. This because the Cisco`s and Brocade`s wouldn't allow
the support of OpenFlow on their devices? I mean why would they
(especially Cisco) when custom hardware and features is their
core business right? Can some one please explain this to me?
Nick McKeown said that Merchant Silicon was a revolution in
itself, at the ONS: https://www.youtube....h?v=W734gLC9-dw
<https://www.youtube.com/watch?v=W734gLC9-dw> 3:05. Lets say
Merchant Silicon didn't exist, what kind of an impact would that
have on OpenFlow? Would the Cisco`s not support OpenFlow and thus
we`d be stuck?
Thanks in advance!
