Re: Nexus network Design - Switching LOOP

I was hoping someone would bite on it ;-)))

lol

- Fabricpath is proprietary
- Qfabric is proprietary and an awful mess IMO ...

- Trill is a draft and the standards group is dead having been rechartered
to work on management protocols and such (recreate the wheel since Trill is
impossible to manage, and does not scale) ... nothing happening in that
standards group except some marketing really. This protocol which rides on
top of L2 has too many holes ... PowerPoint deployments only please.

Industry analyst love drama between vendors and they love buzz words and
trends ... so a lot of articles comparing and discussing the great conflict
of the various methods.

SPB is a standard ... and works everywhere from the smallest network to the
largest SP (16 million isids instead of 4K vlans like the others). SPB
will be on every switch, even on a best buy linksys switch since it is the
replacement to STP. The US military (JITC) certified SPB ...

Standards body: IETF (IP) versus IEEE (Ethernet) - A political
nightmare. Why is Trill not a standard or well defined yet? Too much at
stake ... the vendors with a large install base cannot risk a standard just
yet. This is why Cisco and Juni are concentrating on their own proprietary
protocols.

Which protocol will eventually win, proprietary or standards based? Lol
... the last 30 years has shown that standards always win. Proprietary
never wins in the end ... of course it does come first when no standard
exists and kudos to Cisco and other vendors who have solved problems.

In this case a standard already exists, but vendors need to consider their
share holders and stock prices. Should you base your design and network on
a proprietary, single vendor solution? Up to you I suppose, plenty of
people do! ;-)

A prediction - vendors with proprietary solutions will continue to market
these, protect their install and customer base (billions of dollars and
customer mind-share), but in the end standards will win. Standards always
win in the end.

I think as leaders of the technical community, which this group represents,
we need to push back on our vendors and demand interop test results and
standards compliance. Again this is so important, I believe we need to
push back and tell the vendors to use standards and "may the best product
win".

For those who want to learn more, ask your vendors to compare the
protocols, check NANOG, and then ask them why they chose or did not chose a
standards approach. Watch out for PowerPoint, or misleading answers ...
lol ... do your homework!

HTH in some way, but I probably rambled too much ... HAGN,
Andrew
