Anybody out there have any experience with 10 gigabit ethernet?
I'm looking for switches and routers that actually exist (heh, as opposed
to the kind found in marketing literature). I've heard extreme is
shipping 10 gige stuff. Any news when cisco or juniper will have
something?

I don't think the 10GEA has standarized the draft. It is slated for mid 2002.
But some vendors might have non-standard implementations, but I am not aware of
it.
Most of the stuff available at the 10Gbps rate is OC-192 and has nothing to do
with 10Gbps Ethernet...

Here is an article that states that IntelliSpace and others are already
using 10 Gigabit Ethernet equipment provided by Extreme Networks. It is
skimpy on the details.
I'm trolling to see if anybody in the nanog crowd was willing or able
(NDAs and all) to tell us about any 10 gige equipment they might be using.

IEEE standards web page at http://grouper.ieee.org is quite helpful
for finding the status of the various standards.
In particular, check
http://grouper.ieee.org/groups/802/3/ae/public/mar01/minutes_0301.pdf
for the minutes of the last IEEE 802.3ae Working Group meeting.
Target for completion is 1Q 2002.
At this point, much of the work has been completed, I believe that
all of the outstanding issues were resolved at the meeting and they
have gone to working group ballot (don't ask me about all the details
of the IEEE decision making process, but they are online).
So at least things are close enough that chip sets are being developed
and equipment vendors can get underway with confidence that there
won't be too much change, such that standards compliant products
should be available about in the same timeframe that the standard
is completed.

Anyone know any good articles on 10GB ethernet? I am specifically
intrested if they have removed some of the legacy requirements that hamper
gigabit ethernet (such as a default MTU of 1500, half-duplex, etc.)
Half-duplex? The last time I checked, my GigE equipment didn't default to
half-duplex.
No I wouldn't expect it to, nor did I state anything about defaulting to
half. There is no purpose for half-duplex in GIGE, even the few GIGE hubs
I've seen are buffered and user congestion control to allow full duplex
operation. The possibility of half-duplex mode just adds unneeded cruft
and additional failure modes.
But the ability for half-duplex operation was a requirment in the spec,
for reasons not a whole lot of people can fathom...I have yet to see
anyone actually USING half-duplex GigE, however. FastE, sure (I have a
dumb FastE hub sitting right here on my desk), but never GigE.
