At the risk of diving into the weeds, running rooms 101-105 all from a single switch is going to mean that you have a LOT of very long wires that you have to run to get from one end of the building to the other. Getting these wires under the soft walls exposes them to a substantial risk of damage.
In the past, we have had one switch for each 'speaker room', so with our layout last year, 101/102 had one swich, 103 had a second, 104/105 had a third.
This last year we daisy-chained the APs to save on wire runs (with mixed results, this is one of the things we will need to discuss this year). This is not an option with PoE equipment.
We run far more APs per square foot of space than anyone else I have heard of, but we also have a much better wireless network than anyone else I have heard of, so I would be very leery of anyone proposing a 'normal' density of APs.
For that matter, the facility already has their own wifi network in place. We pay them to turn it off, but if you are going to end up just replicating it, you may as well use what's built-in.

Let's have a call. I need to get a rough count of the hardware that is

does like the idea of supporting SCALE2017 to make a case study out of it.
Ubnt's and my hope is to make the network hardware all ubnt unifi line from
the APs, switches and routers. This will give us full access to all POE
gigabit switches, 10gbit uplinks and all POE wireless AC APs. The whole
system will be centrally controlled by the unifi software.
This is the example of the type of documentation that I did for SELF2016:

of work.

On the schedule from scale14x I see that ballrooms I and J was used but
cant find them on the map.
they are above the D and E sectiosn of the ballroom
For exhibit hall was hall A and B used?
yes, everything
Do i see that right that rooms 101-105 have airwalls between them?
they can, this last year we had 101/102 103 104/105 (three spaces)
What room was used for command/staff
What area was used for noc?
You said in a early email that pre-wired drops was used to connect to the
rooms. How many mdf/idf was used? What was the connect between them.
Is it too early or have you all picked out what rooms will be used?
last year we were still unsure of what rooms would be used for what a
month before the show.
the wiring closet info is part of what we are going to have to discover.
We have fiber between the two building, and copper within the buildings. We
put our own equipment in all of the wiring closets (the only part of the
stock network we used was the in-wall wiring and the router to the outside
world. Everything else was ours.

Hey folks --
long. Your comment about "*All that needs to be done at the show is
I'm sitting out here on the periphery of this discussion (mainly because
I'm more into the audio stuff :), but I did want to throw out some
"scale"
(haha) on the networking effort, since I was involved in a good portion
of
it this past year.
It was interesting to me to see how it all came together, how the
diagrams laid out everything, where the equipment was staged, etc.
Clearly,
someone spent a lot of time planning out things, right down to the
length
of specific cable runs needed in each room on each wall. There was a
TON of
networked gear to distribute and connect. Even if (for the moment) you
discount the internet access points, there was still a lot of work going
into cabling, devices, placement, testing, taping, replacing bad gear,
etc.
Add back in the connection of AP's and it was about double the effort I
just mentioned.
Zach, I love the idea of a vendor-supported internet option, but I would
highly recommend that you talk to some of the folks who laid out gear
last
year and get their input to understand the tremendous work effort that
went
into this on the day before the event. I have huge respect for everyone
who
stuck it out into the wee hours of the morning just to make sure it
worked
the next day.
I came in early on Wednesday to help out. I got there in the afternoon,
and I worked until pretty much midnight (let's say, easily, 6 hours)
just
laying out the networking for the AP's (i.e., not including the cameras
and
pods). And I was one of a team of 6-8 people that night, I believe.
Simply
laying out the cabling took a while, and that's literally just laying
all
of it on the floor according to diagram. Then the AP's were placed and
balanced, making sure that they were under chairs, that the matching
network cables reached, that the correct ports were used, that they were
near power outlets or extension cords, and so on. And finally -- what I
think was the WORST part -- comes the taping down of the cabling and
power
conduits. That took 3-4 people another maybe 2-3 hours just for that one
aspect. And dozens of gaff tape rolls. Tape was everywhere, including
under
moveable doors and panels, along walls, under chairs, across audio
cables,
on stages, etc.
If I had to take an educated guess, I'd venture that the cabling and
placement of AP's probably took 45-50 man hours. Not kidding. Most of us
were also trained network admins, so this wasn't like pulling uneducated
folks off the street; we knew what we were doing, and it still took that
place and connect all of the hardware*" is what I'm referring to here:
about 50 hours of work for JUST THAT. Nothing else. :)
So, while I applaud the enthusiasm and excitement (and especially the
volunteerism!), please keep in mind that this one single aspect of the
show
is a HUGE undertaking. If you go into this and gain a sponsor, you're
still
going to need a big crew, extremely well-placed and planned diagrams,
and
an organized and inventoried stock of cabling and parts. I completely
agree
with Ilan on this -- your help is very welcome and appreciated, but
please
go into this knowing it's going to be a huge effort.
Just my $0.02 anyhow.
Thanks,
Bruce Bergman

Hi Zach,
Excited to see you're so passionate about building out the SCALE
network.
We'd love to have you on board on our volunteer team. Lets sync up and
come to consensus on a plan before reaching out to sponsors. We have a
great deal of hardware that we own already and we should get on the same
page before we make external requests, especially since many of the
hardware vendors sponsor us in other ways at the moment.
I'll defer to the current Tech Chair, who is Bala, on timing but lets
schedule a meeting soon. We're just hitting the time of year where we'd
normally kick off our event planning for 2017.
I believe Bala is traveling this weekend, but I'll add you to the tech
list shortly and we can continue discussing how you can best help the
team.
Thanks again for wanting to make scale awesome.

Oh and any documents of network layout from last year.
mostly these only exist as paper copies. With all the resignations in
Tech after last year (at least 4 significant contributers, including
both
Chairs), I am about the only one with even a reasonably good idea of
how
things were setup. Anything else would involve reverse engineering
things
from the configs. The better approach is to discuss what we want to
do with
the people interested in the design level of things (ideally in
person, a
whiteboard is really desirable for this sort of work), and then setup
this
year's plan from that.
I believe that I am the only person left who had the router password
for this least year, and I never logged into one.

Hi Zach,
Thanks for your interest in helping with SCALE's network and
streaming
needs. I'm coping a few folks that can help answer your questions,
and let
you know where planning stands for 2017 and 2018.
Bala copied here is the interim tech chair, between him, David who
replied a little bit ago, and myself we can help share our current
plans
and let you know where we might need help.
In terms of streaming Michael Proctor, also copied here, leads our
A/V
team which normally run our live streaming and session recordings.
They
record the sessions using IP cameras, and have most of the editing
automated via some software they've written. I'm sure they'd love a
hand
with either the automation tooling or staffing our cameras.
Looking forward to working with you on SCALE 15x.

I hope that this is the right place for this.
I have been asked to reach out the SCALE to see if you all are
in
need
of
help with live streaming, event networking, Wifi or internet
access. I
have
just finished up doing the South East Linux Fest (SELF) Wifi and
was
contacted by Ubiquiti (a hardware maker) and another company
Altispeed
<http://www.altispeed.com/> about sponsoring the networking
needs for
SCALE.
As an example of the event networking I have done, here is the
post I
did
about the SELF2016 network:
http://community.ubnt.com/t5/UniFi-Stories/SouthEast-Linux-Fest-2016/cns-p/1590779
Here is some information about what we've done in the past.
https://www.usenix.org/conference/lisa12/technical-sessions/presentation/lang_david_wireless
https://www.usenix.org/publications/login/april-2013-volume-38-number-2/wireless-means-radio
This last year we deployed about 110 access points around the
show.
The Conference center provides the Internet connection, and we
have
paid them to allow us to run everything else.
There is an opening for them to sponsor some of this. We can
definantly
use help setting up and running things. At the moment, we don't
know who
will be replacing Stu as the person setting up and running the
network for
the show. Michael Proctor-Smith is going to be running the AV
group, so he
will be continuing to spearhead the streaming effort.
The current plan is to select the new Tech Chair in a month or
so.
