I'd just like to say thanks to the NOC. I encountered no difficulties of their making, and several things appeared to work better than before (tm) which is always good.
I had the 1x as my pref from prior IETF and "it just worked".
OSX appears to have gone to a place where stop-start on wifi across sleep/wake is a pain, but I cannot hold the noc responsible for that. Contrariwise, I arrived 2 DAYS before the kick off of 'real' IETF and I had IETF backed net almost immediately.
Well done. Thanks.

I’m not at this IETF meeting and I’m not referring to the current hotel network. In the past, I’ve encountered all sorts of restrictions and limitations. Also, there is often a big difference between the main hotel and the others. In Maastricht, for example, I stayed at what was apparently a dorm hotel and I could not get access to nonstandard ports, e.g. for SSL protected access to my email.SteveOn Jul 25, 2014, at 9:40 AM, joel jaeggli <joelja@xxxxxxxxx> wrote:On 7/25/14, 9:29 AM, John C Klensin wrote:
Steve,
I completely agree with your comment and suggestions (including
at least knowing hotel network capabilities in advance of
arrival), but note that at least some of the reason while the
hotel networks perform so badly under IETF meeting load is that
many of them are seriously underprovisioned at multiple points.
If the meetings team were to perform simple tests (that we
helped design) based on the number of people in that team, they
would be likely to get good information about capability
limitations (e.g., ports and options) but would be unlikely to
get sufficient information about performance under serious load.
Clearly, we could figure out how to run a load test, but I
assume it would take a lot of cooperation from the hotel (or
several hundred of us occupying rooms).
so,
We've taken the hotel's captive portal / nat platform /internet service
out of the path for the residential network for the week. We do this
where possible, and in cases where we cannot this is typically noted.
While wifi coverage, lre/dsl and internal topology are out of our
control, the hotel network is being served by the the IETF network and
has no restrictions respecting authentication, ports available,
middleboxes and so forth. There is nothing especially interesting to
report there.best,
john

If we're going to discuss hotel networks, encryption of the
channel is nice to have but there are more serious problems.
o Many hotel networks restrict the ports that can be reached.
This results in an absolute failure for some of us.
o Many hotel networks do not support the full range of options
for DNSSEC.
o Many hotel networks have very poor bandwidth and become
overloaded when the IETF comes to town.
The meetings team does an excellent job of planning and
running the meetings. They do extensive investigation of each
proposed meeting site and they do a stellar job setting up and
running the networks at each meeting. I wish they would also
test the hotel networks in advance and report to all of us the
limitations we're likely to encounter. And, of course, it
would be pretty easy for a volunteer group of IETFers to
organize a reporting effort too.
