NETWORK
MAP
The Marriott hotel is linked to the Internet via a DS3
provided by Sprint.
Terminal Room
The conference site features a Cisco-sponsored terminal room with 15 PCs,
a printer, and a number of stations for laptop users. The room will also
have 802.11b wireless connectivity.
The terminal room is in the OCC
Extension next to 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 room will have tables set up with ethernet ports for laptop
users. The room will also have 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 wireless
security.
Cisco and Merit are providing 200 wireless cards for loan to attendees
during the meeting. Cards will be available on a first-come,
first-served basis at the registration desk on Sunday, and thereafter
in the General Session room. There will be connectivity for people
with:
- 802.11b Compliant, Direct Sequence
Spread 2.4 GHz (DS) cards
(2 Mb/s and 11
Mb/s)
At this meeting we will not be supporting:
- Legacy 2.4 GHz DS (e.g. WaveLAN)
- Legacy 915 Mhz DS (e.g. RoamAbout)
Checkout Procedure
- Locate the wireless desk; it will be in the registration area on
Sunday and in the back of the General Session room (OCC East) on Monday
and Tuesday.
- 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 General Session room
(not to the registration desk.) Your name will be checked off as having
turned in your card, and you're all set. In the unfortunate event that
you lose or break the wireless card, your credit card will be
charged the price of the wireless card (approximately $125).
Wireless Specs
If you already own a wireless card, please feel free to bring it. If you
are looking to buy a wireless card, you should probably get any brand of
card that offers IEEE 802.11 compliancy. IEEE 802.11 is a somewhat new
standard for wireless LAN's, and is a safe bet for future compatibility.
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 the CDs provided with some wireless
cards, and on the web:
The latest wireless info should be posted here and updated as the
setup progresses. Check here often if you're having any problems.
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 NANOG23 cache uses Squid, a freely available Web
proxy
cache.
Multicast
Note: Mac users can receive the MPEG-1 stream using MacTV. See http://www.iwitnesstv.com/.
With help from Cisco and the University of Oregon, we will be
generating two types of multicast streams. The primary
video codecs used to encode the video are H.261, MPEG-1, and MPEG-2.
- H.261 Broadcast. The H.261 stream will be visible to users with
the standard multicast tools from the UCL Mbone
Conferencing applications archive, and most other free and commercial
tools that can can handle H.261/PCM. For information about setting up
MBone tools for Windows95/NT, Macintosh, and Unix, see:
http://videolab.uoregon.edu/tools/multicast_tools.html
- MPEG-1 Broadcast. The MPEG-1 stream will be generated using
IP/TV, a streaming video server from Cisco. The IP/TV MPEG-1 stream will
be visible either with a liscensed or demo version of IP/TV or with MIM, a
UNIX MPEG streaming client developed at the University of Oregon:
http://videolab.uoregon.edu/mim
Users can obtain IP/TV 3.0 from:
http://videolab.uoregon.edu/download.html
- MPEG-2 Broadcast. The MPEG-2 stream will be usable by a small
subset of clients.
In SDR the session names will be:
- NANOG 23 (H.261)
- NANOG 23 (MPEG1)
- NANOG 23 (MPEG2)
If you're not using SDR, the session names 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
NANOG 23 is also being broadcast with Real Network's G2 server. 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.
