Sure, should we also require that Native IPv4 be provided?  For example:

    Native IPv6 and IPv4 MUST be provided

I could add a reference to

I will change to “Deep Packet Inspection (DPI) filtering"

Will do.

How about:

   o  The meeting facility SHOULD support the deployment of additional
      wireless networks including techniques to limit interference such
      as limiting radio power, software-based radio control, and or
      physical separation.

> - re " The meeting facility SHOULD have installed network cabling that can be used to deploy the network infrastructure." Perhaps you can be more specific? I think you are asking for at least one GigE drop in each meeting room in order to provide backhaul for WiFi APs, with ballrooms and larger meeting spaces to be able to accommodate additional GigE drops. But that sort of seems covered in Section 4?

I think having this be more specific would be good.   Can someone suggest some text?

I checked with AMS, they need a wired drop for a printer.

I think it’s usually open before and after scheduled IETF meeting.  If we don’t want to have it open 24 hours, then 6am to Midnight might work.  We do have lots of jet lagged people at these meetings :-)

I wonder if we have any data on usage?

> - s/ network connected/ network-connected
> - Is an enterprise class printer required? -->Maybe just spec a laser printer and be done with it. I suspect print volumes are rather low. If there was a slow inkjet that may cause problems. ;-)

I think we usually just have a networked color inkjet printer.   They may even buy a new one before each meeting as it’s cheaper/easier to store/ship/maintain.

I propose the following to replace this and the following item:

   o  The terminal room MUST include a networked medium capacity color
      printer with duplex capability.

Perhaps citing what we are currently use might be helpful, and better define “medium capacity”.

> - Re There SHOULD be a manned help desk --> Why? Is this often used? Could it be a sign that directs someone to the NOC room for help? Or explains how to ticket an issue?

I think it is used frequently, thought the NOC folks might have some data.  I have used it :-)

We have a range of people with various technical abilities in the IETF.  They often need this kind of support.

> - 4.2 - 1st bullet has an incomplete couple of sentences. Maybe the period was meant to be a comma?


   o  The network design MUST anticipate simultaneous usage of 100% of
      the projected number of attendees in each meeting room.  The
      number of wireless network users in excess of 1000 simultaneous
      wireless users has been observed during a plenary session.

That said, 100% is probably too low.  I would think it should be 200%.  For example, I have my laptop and phone on the wireless.   Apple watch type devices will increase that even more.  Maybe 250% is about right.

> Section 5:
> - A document must be provided? As in a physical piece of paper? Or can this info be on the meeting website or on a sign someplace? Maybe change document to instructions?

Good point.  How about:

   o  Online documentation MUST be provided to attendees detailing on-
      site network configuration information, including wireless
      configuration details, services available (e.g., printing),
      instructions on how to report network issues (e.g. trouble ticket
      system interface instructions), etc.  Initial versions of this
      information SHOULD be provided in advance of the meeting.  This
      should be provided on the IETF meeting website and distributed to
      attendies via email.
