Logical | Physical

The Sheraton Parkway is linked to the Internet via an OC3 ATM backbone connection provided by Group Telecom, with Internet2 transit and multicast provided by ONet and CA*net4.

Terminal Room

GT 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 Unionville/Buttonville rooms down the hall from the Ballroom, 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 Unix workstations is:

  login: nanog
  password: nanog

Main Room

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.

Wireless Connectivity

Please read our note about cleartext passwords.

Merit is providing 200 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.

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

Locate the wireless desk; it will be either in the registration area or the back of the main ballroom.
We will take a credit card number to ensure timely return of your card :-) .
On Tuesday (or earlier if you wish), please return the cards to the wireless desk in the ballroom (not to the registration desk.) Your name will be checked off as having turned in your card, and you're all set. If you lose or damage the card, your credit card will be charged the price of the wireless card (approximately $250).

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

Drivers are available on-site on CDs provided with some wireless cards, and on the web:

Cabletron
Lucent WaveLAN

BayStack Drivers -- select "Software Downloads" from the menu on the left-hand side of the page. On the next page, click "View by a Product" and select your product from the drop-down list. Click "Save" and you'll be taken to a page where you can download drivers.

For help installing your card, see the engineers at the Group Telecom 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 NANOG24 cache uses Squid, a freely available Web proxy cache.

Multicast

The NANOG multicast broadcast is produced by the University of Oregon, with help from Cisco and Sprint.

To pick up multicast client software see:

http://videolab.uoregon.edu/download.html

You can test your multicast connectivity here:

http://www.on-the-i.com/mt/index.html

Broadcast Types

The H.261 broadcast will be visible to all users with a standard multicast client.
The MPEG-1 broadcast is generated using IP/TV, a streaming video server from Cisco. Client tools are available from the University of Oregon Video Lab.
The MPEG-2 broadcast will be usable by a small subset of clients.

Session Names

In SDR and iptvhost.uoregon.edu the session names will be:

NANOG 25 (H.261)

NANOG 25 (MPEG1)

NANOG 25 (MPEG2)

If you're not using SDR, the session information will be:

H.261

video - 224.2.246.93:52720

audio - 224.2.129.33:27324

MPEG1

video - 224.2.242.11:52798

audio - 224.2.184.125:30776

MPEG2

video - 224.2.133.187:60294

audio - 224.2.229.231:29482

Feedback or questions about the multicast sessions can be sent to multicast@lists.uoregon.edu

RealNetworks Streaming Media

NANOG 25 is also being broadcast with RealNetwork's RealServer 8.0. 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 connectivity to the 6Bone via a tunnel back to Merit's location in Ann Arbor. 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.

DHCP

These graphs show information from the NANOG DHCP server. The first graph shows the number of IP addresses assigned and the number of MAC addresses making DHCP requests. The second graph shows the rate at which addresses are assigned.
