Subject: [95all] IETF 95 Network Information – Buenos Aires, Argentina

From: Jim Martin <[email-masked]>
Date: Sat, 2 Apr 2016 12:49:56 -0300

Gentlepeople,

	This is a rough text extraction of the canonical Network Information page at  https://tickets.meeting.ietf.org/wiki/IETF95network <https://tickets.meeting.ietf.org/wiki/IETF9network> - Please check that out, as it’s clickable and gets updated!

	There are two particular things to note beyond the usual network information: the Hilton guest room Internet details and the addition of user experience probes.

	As we do at all IETF Headquarters Hotels, we’ve deployed the IETF network to the guest rooms using the existing hotel infrastructure here in the Hilton.

	The good news:  Each hotel room has its own AP and wired ethernet (integrated into the wall port, next to your desk). These access points are designed for dense deployments, and so the APs are designed to cover "a small space of *up to* 430 square feet (40 square meters)."

	The bad news: 430 square foot is slightly less than 21ft * 21ft (6m x 6m). The distance from the AP to the middle of the bed is ~15ft (4.5m). This means that if you try to use your wireless from the bed you are towards the limit of the design range and may get poor throughput. From the bathroom you are unlikely to get anything. Additionally, these are not particularly high performance APs, and provide a maximum throughput of around 15Mbps even when very close.

	If you need higher performance, the wired connection is a 100Mbit ethernet.

	Additionally, we’ve strategically deployed 17 user experience probes throughout the meeting space. The probes are designed to gather throughput data "as if" they were users. They run various processes including pings, http requests, traceroutes, and DNS queries. They collect no data about other users, personal or otherwise. If you see these NetBeez contributed boxes or similar devices, please don’t disturb them as they’re doing important work to help us monitor and improve the network experience here at IETF95.

	Have a good meeting and let us know (at [email-masked]) if you have any questions or issues with the network!

	- Jim

== Terminal Room ==

The Terminal Room is located in Pacara B, which is on the 5th Floor past the Business Center and on the left. The Terminal Room is open 24 hours each day beginning Sunday, 3 April, 2016 at 16:00 and ending on Friday, 8 April, 2016 at 15:00. A help desk is being provided, hours are listed below.  The room itself consists of approximately 50 seats, providing some wired access and 220v universal power ports. There is also an HP Officejet Pro 8620 printer available.

Please note that this terminal room has no terminals, PCs, or other user-accessible machines. It is simply a place to get power, wired Internet access, help desk support, and/or print documents.

When using the Ethernet connections in the Terminal Room, IPv4 addressing is provided via DHCP. Please use Dynamic Auto-configuration for IPv6. A stateless DHCPv6 server or RDNSS will provide network information. To cut down on the mess, ethernet cables have not been installed to every seat in the Terminal Room. If you need a cable, please ask at the Help Desk.

Please note that at the request of the IETF Chair, demonstrations are no longer permitted in the Terminal Room.

== Help Desk ==
A help desk is being provided and will be staffed the following hours:

|| Sunday        || 16:00 to 19:00 ||
|| Monday       ||  8:00 to 20:00 ||
|| Tuesday      ||  8:00 to 20:00 ||
|| Wednesday ||  8:00 to 20:00 ||
|| Thursday     ||  8:00 to 20:00 ||
|| Friday          ||  8:00 to 15:00 ||

== NOC and Ticketing ==

There are several ways to communicate with the NOC staff.
 * Submit a new trouble ticket via the [http://tickets.meeting.ietf.org/newticket "trac web"] interface. Filling in the following fields: "My MAC Address", "My Current Location", and "My OS" may expedite ticket processing. If you have an existing account on http://tools.ietf.org you can use your established credentials (email address and tools password) to [http://tickets.meeting.ietf.org/login "log in"].
 * Send an email to [email-masked]`''' with as much detail regarding your issue and configuration as possible.
 * If you're on site and need direct network assistance (i.e - you have no network) please go to the helpdesk, which is located in the Terminal Room.
 * Use the Jabber room at noc @ jabber.ietf.org to report issues or communicate with the NOC.

You can also use trac to review outstanding tickets before reporting an issue or to update outstanding tickets.

=== External Connectivity ===

The IETF 95 network connects to the Internet via two 1Gb/s uplinks from Level 3, and a 1Gb/s link from IPLAN. The IETF uses 31.133.128.0/18, 31.130.224.0/20 and 130.129.0.0/16 for IPv4 and 2001:67c:1230::/46, 2001:67c:370::/48 and 2001:df8::/32 for IPv6. We are supplying bandwidth for the conference space, as well as wireless and wired connections in the guest rooms.

== Meeting Room Wireless ==

An 802.11 a/g/n/ac wireless network is provided throughout the venue on both the 2.4 and 5 GHz bands, in conjunction with IPv4 and IPv6 addressing options.

The main “ietf” wireless network is now encrypted; when prompted for credentials, enter ietf for both the username and password.

Here’s a quick summary of the network layout:

|| SSID             || Description                                                           || Encrypted || Frequencies   || IP Versions ||
|| ietf                 || Our default network                                             || yes            || 5Ghz only       || v4 and v6 ||
|| ietf-legacy     || For legacy and unencrypted use                         || no              || 2.4 and 5Ghz || v4 and v6 ||
|| ietf-2.4ONLY || An encrypted network for 2.4Ghz users              || yes            || 2.4Ghz only    || v4 and v6 ||
|| ietf-v6ONLY || For users wanting a pure IPv6                              || yes            || 5Ghz only       || v6 only ||
|| ietf-nat64     || IPv6 stack with NAT64 to access IPv4 resources || yes            || 5Ghz only       || v6 with NAT64 & DNS64 ||
|| eduroam      || educational users                                                  || yes            || 2.4 and 5Ghz || v4 and v6 ||

All networks marked as encrypted will offer layer 2 security. This is done using WPA enterprise with 802.1X (PEAP or TTLS) authentication and AES encryption. As usual, we are all using the same credentials (user “ietf”, password “ietf”), yet each user will get unique session encryption keys. Our Radius authentication servers use a certificate that you can verify by going to this page: [https://tickets.meeting.ietf.org/wiki/IETF95wireless]

== Guest Room Access ==

The IETF Network is being extended to the guest rooms in the Hilton. *Note* that while we are using the IETF meeting network for Internet connectivity, we are using the hotel's infrastructure (HP access points) for the delivery to the guest rooms, so there are limits to the improvements we can effect.  We recommend using the wired connection if you experience poor connectivity in your guest room. Each room (with the exception of the 4 largest suites) is equipped with a combination Access Point and Ethernet Switch integrated into the wall port next to your desk.

Wired:
	IPv4 and IPv6 and provided via the wired connection in your room. The unblocked port in the lower right hand corner of the switch is providing the IETF network at 100mbps.

Wireless:
	In the guest room areas you should find the “ietf-hotel” SSID.  This network is 2.4GHz ONLY and is being delivered via the access pointing your room. The APs in the this hotel are designed for very dense AP deployments. This means that they have very limited range, and so you may need to be very close to it (next to your desk) to get useful connectivity.

== Support ==

If you have trouble using any of the Public or Guest Room services, please try to switch to the hotel SSIDs ("hhonors") or the hotel wired port.  If that doesn’t work, please contact the Hilton support as listed in your room. If things are working fine on the hotel offerings but not on the IETF SSIDs/ports, please do contact us in the Terminal Room (Pacara B) or via tickets @ meeting.ietf.org  and we’ll be glad to help!

=== A Note For Windows Users ===

Connecting to the IETF SSID on Windows XP/7 requires a few extra, non-intuitive steps. If you're struggling to get connected to an encrypted SSID on your Windows laptop, please come by the Help Desk. Alternatively, you can try yourself; Instructions are here >> [https://drive.google.com/file/d/0ByW1F7U2HIVXWC11OXRfOTZwNE5sbnU1ejNRYWxsYzR0R0hN/view?usp=sharing]

== Printing ==

There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP Officejet Pro 8620 and is accessible via LPD, Bonjour, standard TCP/IP on port 9100.  The hostname for it is term-printer.meeting.ietf.org.

|| Name || Model || Capabilities || IPv4 Address|| IPv6 Address || Notes || Drivers ||
