Network Map


Connectivity

The Weston is linked to the Internet by a 50M fast Ethernet connection provided by Yipes Communications and multicast connectivity provided by Swift Communications and the University of Oregon. IPv6 traffic will be tunneled back to Merit and out to the Internet via Abilene.

Network Authentication

Merit's wireless authentication system helps us isolate problems on the wireless net.

To access the wireless network, launch your browser. You'll be redirected to a gateway server and prompted for your email address. Once registration begins at noon on Sunday, you must enter the email address you used to register for the meeting. If you're not sure what address was used for registration, check with the staff at the wireless desk or the registration desk.

Once you enter your email address, the gateway server will record your assigned DHCP address and MAC address. Your HTTP session will then be redirected to the URL you originally entered in your browser.

Mail Relay

If you need a local mail relay, use smtp.nanog34.merit.net.

Terminal Room

Switch and Data has equipped the NANOG terminal room with 15 workstations, a printer, outlets and ports for laptop users, and 802.11/802.11b wireless connectivity.

The terminal room is in the Grand Crescent room on the Grand level of the hotel, and will be open from Sunday afternoon to the end of the meeting, with 24-hour access. You will need your NANOG badge to enter.

The account on the Windows XP workstations is:

  login: nanog
  password: nanog

Ballroom

The main ballroom will have tables set up with ethernet ports for laptop users, as well as wireless connectivity. We're also hoping to get wireless connectivity to the bar area(s), and to the Beer 'n Gear. Connectivity to the Beer 'n Gear is not guaranteed.

Please read our note about avoiding cleartext passwords on the wireless net.

Authentication
Merit's wireless authentication system makes it easier for us to isolate any problems with the wireless net.

Once registration begins at noon on Sunday, you must enter the email address you used to register for the meeting. If you're not sure what address was used for registration, check with the staff at the wireless desk.

Once you enter your email address, the gateway server will record your assigned DHCP address and MAC address. Your HTTP session will then be redirected to the URL you originally entered in your browser.

Card Loans
Merit is providing wireless cards for loan to attendees during the meeting. Cards will be available in registration area on Sunday afternoon, and in the main ballroom on Monday and Tuesday.

SSID
The wireless network SSID is nanog34 .

Supported Cards
The network supports 802.11/802.11b-compliant, Direct Sequence, spread 2.4 GHz (DS) cards (2 Mb/s and 11 Mb/s).

Addressing
All wireless addresses for the meeting are in the 192.35.164.0/22 block.

Checking Out a Card
Pick up your card in the Terminal Room (Grand Crescent.) You must return the card to the wireless desk in the Terminal Room following the meeting. Your name will then be checked off as having turned in your card, and you're all set. If you lose or damage the card, you will need to pay for it. (The cost is approximately $90.)

If you already own a wireless card, please feel free to bring it. If you are thinking about buying a wireless card, you should probably get any brand of card that offers IEEE 802.11 compliancy. You'll probably want to get a card that uses Direct Sequence technology, as frequency hopping has a lower maximum theoretical bandwidth (2Mb/s).

Drivers
If the following options are available in your driver, you'll be best served by setting:
  • Access point density high
  • Power saving off
  • Infrastructure/bss mode only
  • Drivers are available on-site on CDs provided with some wireless cards, and on the web: For help installing your card, ask at the wireless desk or check with the Merit staff.


    Squid Cache

    Take advantage of the NANOG Web cache! Traffic analyses from recent meetings show that on average, it's approximately twice as fast to load a page from the cache than from the origin server directly. In addition to saving bandwidth, caching reduces the load on the Web sites you're accessing, and gives you lower latency to overseas hosts.

    Follow these steps to configure your browser to use the cache. The NANOG cache uses Squid, a freely available Web proxy cache.


    Multicast

    NANOG will be multicast live using an ISMA MPEG-4 standard multicast stream using the AAC audio codec at 250Kb/s. The stream should be of similar visual quality to the 1Mb/s MPEG-1 stream! Recommended free clients are Quicktime for Windows or Macintosh and MPlayer on Linux or *BSD. The VideoLAN client is able to play back the video on all platforms but the AAC audio properly on only a few of them.

    The multicast sources are:

    MPEG-4 (ISMA MPEG-4 250kb/s)

    Please send feedback or questions about the multicast session to nanog-support@nanog.org


    RealNetworks Streaming Media 

    NANOG is also being broadcast with RealNetwork's RealServer 8.0. The broadcast begins Monday morning at 9:00 a.m. To view the live or archived feeds, you can use RealPlayer 5.0 and above. To watch the meeting live, check the links on the main conference page. If you have questions about the Real Media broadcast, check with the Merit staff or send e-mail to nanog-support@nanog.org.

    IPv6

    All NANOG wireless and terrestrial ethernet ports will be IPv4/IPv6-ready. The NANOG conference site will have native IPv6 connectivity via Merit's link to Abilene/Internet2. You'll want to use IPv6 stateless address autoconfiguration (
    RFC2462). We do not provide static IPv6 addresses.

    IPv6 implementations for various laptop platforms are available from ipv6.org. If you have questions about v6 connectivity, please check with a Merit/NANOG staff member or send email to nanog-support@nanog.org.
