The IETF 60 Network: A Volunteer-Built Success Story

The IETF 60 network faced a significant challenge when initial equipment was lost in transit, leading to a complete overhaul of the setup by dedicated volunteers. With over 80% of the original hardware missing, a last-minute assembly of equipment from Cisco, Priority Networks, and more was initiated. Connectivity was restored two days after installation began, featuring a robust DS-3 landline and wireless backup. This setup supported numerous users, successful DNS queries, and demonstrated strong wireless performance throughout the conference, earning praise from participants.

  2. Network that almost wasn’t • No host found, so the IETF 60 network was built entirely by volunteers • 80%+ of the equipment LOST in the shipping ether • Current network built entirely out of last second replacement equipment from Cisco, Priority Networks and others • Lost two days of install, began Friday morning

  3. Internet Connectivity • DS-3 (45M) landline, 1.5M Wireless backup from NetHere. Routers from Cisco and Juniper. • Peaks of ~17Mbps in both directions. • IPv6 via a tunnel from Itojun (IIJ) • IPv4 multicast via a tunnel from Greg Shepherd (ISC)

  4. Wireless • 20 802.11b Access Points from Cisco, spread through the conference area, east lobby/bar and the west wing lobby. • 3 Wireless VLANs • Open (ietf60) • WEP (ietf60-wep) • 802.1X (ietf60-1x) • Constant analysis from 4 remote probes from AirMagnet

  5. Random Statistics • Total unique MACs via DHCP: 1532 • By network: • Open Wireless East: 1115 • Open Wireless West: 218 • WEP Wireless: 47 • 802.1X Wireless: 11 • Wired Terminal Room: 303 • Static IPv4 assignments: 5 • Maximum of 143 associations on one AP • Peak simultaneous wireless users: 890 • 3250 pages printed (double-sided!) • 506,000+ successful DNS queries • Complaints on the IETF list: 0 [THANK YOU!]
