Remember to bring your wireless card to the meeting!

NETWORK MAP

The Inter-Continental hotel is linked to the Internet via a Stratum 20 Mb/s microwave radio link provided by Terremark with transit provided by Qwest.

Terminal Room

 The conference site features a Terremark-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 Escorial Room around the corner 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 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.

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

Merit is 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: Checkout Procedure

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). 

   Specific Setup:
   Global Settings:
	Domain: 0001
	Beacon: 1e1f
	IEEE Name: nanog

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 NANOG24 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 the University of Oregon, Cisco, and Sprint, 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.

  1. 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
  2. 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
  3. MPEG-2 Broadcast. The MPEG-2 stream will be usable by a small subset of clients.
In SDR the session names will be:

NANOG 24 (H.261)
NANOG 24 (MPEG1)
NANOG 24 (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

Real Media   

NANOG 24 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.
