     3== Terminal Room ==
     5The Terminal Room is located in ORD/Blundell which is adjacent to the South Atrium. The Terminal Room is open 24 hours each day beginning Sunday, November 12th, 2017 at 16:00 and ending on Friday, 27 November, 2017 at 15:00. A help desk is provided and the hours are listed below.  The room itself consists of approximately 50 seats, providing some wired access and 220v power ports. There is also an HP Officejet Pro 8710 printer available.
     7Please note that this terminal room has no terminals, PCs, or other user-accessible machines. It is simply a place to get power, wired and wifi Internet access, help desk support, print documents, and/or work quietly.
     9When using the Ethernet connections in the Terminal Room, IPv4 addressing is provided via DHCP. Please use Stateless Auto-configuration for IPv6 (SLAAC). A 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.
     11Please note that at the request of the IETF Chair, demonstrations are no longer permitted in the Terminal Room.
     13== Help Desk ==
     14A help desk is being provided and will be staffed the following hours:
     16|| Sunday || 16:00 to 19:00 ||
     17|| Monday ||  8:00 to 20:00 ||

     23== NOC and Ticketing ==
     25There are several ways to communicate with the NOC staff.
     26 * Submit a new trouble ticket via the [ "trac web"] interface. Filling in the following fields: "My MAC Address", "My Current Location", and "My OS" expedite ticket processing. If you have an existing account on you can use your established credentials (email address and tools password) to [ "log in"].
     27 * Send an email to '''`tickets @`''' with as much detail regarding your issue and configuration as possible.
     28 * If you're on site and need direct network assistance (i.e - you have no network) please go to the Help Desk, which is located in the Terminal Room.
     30* Use the Jabber room at noc @ to report issues or communicate with the NOC.
     33You can also use trac to review outstanding tickets before reporting an issue or to update outstanding tickets.
     35The Secretariat also maintains a ticket system for the reporting of meeting issues. Please send
     36mail to: '''`mtd`''' to report a problem. The Secretariat is responsible for addressing issues with:
     38    * A/V in meeting rooms
     39    * Beverage and food
     40    * Jabber
     41    * Projectors
     42    * Temperature fluctuation
     46== External Connectivity ==
     48The IETF 100 network connects to the Internet via multiple 1Gb/s uplinks donated by Starhub, NTT Communications, ViewQuest, and Moratelindo. The IETF uses 2001:67c:370::/48 and 2001:67c:1230::/46 for IPv6 and and for IPv4. We are supplying bandwidth for the conference space, as well as wireless connections in the guest rooms of the Swissotel, and Fairmont hotels..
     50== Meeting Room Wireless ==
     52An 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.
     54''The main “ietf” wireless network is encrypted; make sure you enter ietf for both the username and password.''
     56Here’s a quick summary of the network layout:
     58|| SSID || Description || Encrypted || Frequencies || IP Versions ||
     59|| ietf || Our default network || yes || 5Ghz only || v4 and v6 ||
     60|| ietf-legacy100 || For legacy and unencrypted use || no || 2.4 and 5Ghz || v4 and v6 ||
     61|| ietf-2.4ONLY || An encrypted network for 2.4Ghz users || yes || 2.4Ghz only || v4 and v6 ||
     62|| ietf-v6ONLY || For users wanting pure IPv6 || yes || 5Ghz only || v6 only ||
     63|| ietf-nat64 || IPv6 stack with NAT64 to access IPv4 resources || yes || 5Ghz only || v6 with NAT64 & DNS64 ||
     64|| ietf-nat64-unencrypted || IPv6 stack with NAT64 to access IPv4 resources || no || 5Ghz only || v6 with NAT64 & DNS64 ||
     65|| eduroam || educational users || yes || 2.4 and 5Ghz || v4 and v6 ||
     67All networks marked as encrypted will offer layer 2 security. This is done using WPA2 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. Stefan Winter has kindly provided signed profiles that will supply the appropriate SSL certs:
     69Our wireless LAN infrastructure implements the following two BCP38-like filtering.
     70* Packets from manually configured IPv4 addresses that are not assigned by DHCP are dropped. DHCP packets are snooped by our wireless LAN controllers to perform this filtering.
     71* Packets from IPv4 and IPv6 addresses that cannot be resolved via ARP/NS are filtered out. Proxy ARP/ND is performed by our wireless LAN controllers for this filtering.
     73== Experiments ==
     75Experiments on the IETF network need to be approved by the IETF Chair.  For IETF 100, the following Experiment has been approved and has been implemented:
     76    * DNS-over-TCP (DPRIVE) - Information can be found [wiki:IETF100Experiments "here"]
     79== Guest Room and Public Space Access ==
     81The IETF Network is being extended to the guest rooms and public spaces throughout the Prague Hilton.  This is being delivered via the hotel's wireless infrastructure as an additional SSID, "ietf-hotel". 
     83**Note** If you have performance issues with this network, please let us know. Please note though, that while we are using the IETF meeting network for Internet connectivity, we are using the hotel's infrastructure for delivery to the guest rooms and public space, so there are limits to the improvements we can effect. 
     85== Support ==
     87If you have trouble using the guest room and public space SSID "ietf-hotel", please contact us in the Terminal Room (Sofia room) or via '''`tickets @`'''  and we’ll be glad to help!
     89=== A Note For Windows Users ===
     91Connecting to the ietf SSID on Windows 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 >>
     93== Printing ==
     95There is a printer in the Terminal Room and is available to all IETF users. The printer is an HP !OfficeJet Pro 8710 and is accessible via LPD, Bonjour, standard TCP/IP on port 9100.  The hostname for it is  This printer is compatible with the !OfficeJet Pro 8620 we've used in previous meetings, so if you were able to use the printers previously, this one should "just work".
     98|| Name || Model || Capabilities || IPv4 Address|| IPv6 Address || Notes || Drivers ||
     99|| || HP Officejet Pro 8710 || Inkjet w/Duplexer || || 2001:67c:370:160::18 || Bonjour name: // term-printer // || [ Printer Drivers] ||
