2004 was a great month for IPv6. After the success
of the first ever West Coast USA IPv6 Summit (San
Diego, at San Diego State University), we had a burst
of growth in both attendees and sponsors for the send
West Coast IPv6 Summit, in Santa Monica, about 10
miles west of downtown Los Angeles.
500 attendees, 20 corporate sponsors, 4 nonprofit
sponsors, and 10 media sponsors converged at the Loews
Hotel in Santa Monica from June 14-17, 2004. Attendees
heard 50 world class experts on IPv6 and the new Internet,
from the Department of Defense, Department of Homeland
Security, leading technology companies, leading universities,
and international associations. Highlights included
presentations by 3 of the people most directly responsible
for creating the Internet, including Lawrence Roberts
(former director of the ARPANET), Larry Smarr (director
of Cal-(IT)² and former director of NCSA when
the Mosaic webclient and Apache webserver were unleashed
upon the world), and Vint Cerf, who received a standing
ovation for his efforts in creating the Internet.
In this issue we are pleased to have several of the
speakers from the summit drill a little deeper into
the areas of IPv6 Security, Moonv6,
and OSPF. We also have the great
priviledge of publishing Yves Poppe, whose PowerPoints
on Teleglobe's IPv6 adoption plan are creating a buzz
within both the IPv6 and the wider telecom community.
Finally, my friend and colleague at IPv6 Summit, Chris
Harz, speculates on the topic of IPv6
and Location Based Gaming. We wish you luck with
your IPv6 activities! Let us know if you want to share
your successes with 6,000 of the brightest people
in the Internet, the subscribers to 6Sense.
the IPv6 Chasm: The Teleglobe Case Study
Teleglobe as global Internet Service Provider
Teleglobe is a Canadian based global international
carrier and operates a worldwide voice and data network.
It has capacity in about 100 international cables
and recently acquired Princeton, NJ-based ITXC, the
world's major VoIP wholesale carrier.
Teleglobe operates a global IP network under one Autonomous
System (AS6453), and has more than 40 major international
POP locations in North America, Europe, Asia/Pacific
and the Middle East. Backbone interconnectivity is
based on multiple OC-48s and OC-192s. It is a Tier
1 network peering with all other Tier 1 carriers at
over 70 public peering points. Teleglobe operates
as a wholesaler and provides Internet access to carriers
and ISPs in 93 countries, ranging from Algeria to
Zimbabwe. Teleglobe operates a Cisco-powered network

Address expansion is probably the most well known
feature of IPv6. The problem of IPv4 address space
shortage, however, is more critical to the private
sectors, and is less applicable to the networks under
the control of the US government agencies and the
various sectors within the US armed forces. The statement
that IPv6 brings more security related values to network
infrastructures and communications also needs closer
examination. For example, the end-to-end secure communication
model is a reality in IPv4 when globally unique address
assignments are possible. Many of the security problems
that plague IPv4 operations remain in the IPv6 realm.
On the other hand, many of the new features in IPv6
introduce additional threats and require much more
thoroughful analysis and demand more sophisticated
solutions. Clearly, those other features of IPv6 such
as the improved Quality of Service as discussed by
Dr. Lawrence Roberts, IPv6 Mobility, reduction in
the complexity of network management and the routing
infrastructures, are just some examples of benefits
from IPv6, which are important to the Department of
Homeland Security (DHS), and to DoD in aiding its
construction of the Global Information Grid (GIG).
Mobility and secure communication over various types
of wireless infrastructures are critical to ...
and Location Based Gaming
Based Gaming (LBG) is a specialized form of videogaming
that takes advantage of the fact that the network
knows where each user is. This allows the game landscape
to incorporate real world elements of the location
that the players are located in. In a city, for instance,
an LBG can interleave the player's ordinary experience
of the city with the extraordinary experience of the
game. Location based gaming is very new - so new that
no major companies have established dominance in this
market yet - but is the most dynamic segment of the
mobile games market, which in turn is the fastest
growing segment of the huge videogame market.
The fidelity and richness of content of such games
is at present relatively low. Most present LBGs such
as BotFighters in Sweden are played with cellphones
- the players know where they are within a few hundred

"The Spirent tools greatly enhanced our testing
capabilities and enabled my test team to test performance,
conformance and mobility." - Major Roswell
V. Dixon, Joint Interoperability Testing Command (JITC)
tactical data systems/IPv6 test director.
Spirent helps test deployment of next-generation
Today's Internet has run on Internet Protocol version
4 (IPv4) for over 20 years. Because its planners never
expected its popularity, today there's a growing shortage
of IP network addresses-a problem that is only intensifying
with the proliferation of Internet-enabled devices.
Fortunately, the next-generation Internet protocol,
IPv6, not only solves this problem but also improves
network routing and configuration processes. Designed
by the Internet Engineering Task Force (IETF), IPv6
is expected to gradually replace IPv4.
and IPv6 White Paper
Dean Lee and Dennis Crowe, Ixia
OSPF has been adapted to support IPv6 in RFC 2740
(OSPFv3). All fundamental mechanisms of OSPF remain
unchanged, such as flooding, areas, DR election, SPF
route calculation, etc. However, some changes are
needed to accommodate IPv6:
All addressing semantics were removed from OSPF
packet and LSA headers.
New LSAs have been created to carry new IPv6
addresses and prefixes.
OSPFv3 now runs on a per-link basis, instead
of on a per-IP-subnet basis.
The flooding scope for LSAs has been generalized.
Authentication has been removed from the OSPF
protocol itself, which relies instead on IPv6's
