We are just six weeks away from the first Coalition
Summit for IPv6, which takes place from May 23 to
26. I’m excited about meeting hundreds of our
6Sense readers, perhaps including you. If you join
us at the Hyatt Regency in Reston, you will have the
opportunity to hear and speak with 50 top authorities,
including CIOs, generals, IPv6 transition plan writers,
business executives, standards group leaders, entrepreneurs,
inventors, and others whose work involves and influences
IPv6. Dozens of countries are expected to send IPv6-savvy
delegates to share their nations’ v6 project
results and to join the great discussion about how
to transition to the New Internet.
There are advantages for the US and its allies, its
Coalition Partners in the largest and most inclusive
sense, to move to IPv6 at the same rate, with similar
standards and definitions, and to share the results
of research, development, and deployment. With coordination,
the best applications can reach 50 to 100 nations
rapidly. Without coordination, tens of billions of
dollars or euros could be wasted simply reinventing
the wheel. Over $500 million in government funds have
been spent outside the US on IPv6, and savvy American
delegates will be able to leverage that knowledge
so that it can also be put to use in the US. If there
were to be an absence of visionary leadership, standards,
and carrots and sticks to have everyone using the
same IPv6, we might end up with different nations
or corporations making changes in the protocol itself,
in IPsec, in QoS, or in applications like satellite
video or VoIPv6. Some have started to wonder whether
there will be different subversions of version 6 emerging
in Europe, Asia and the US. This Coalition Summit
for IPv6 is the place to make a stand for a single
unified version 6 that exemplifies global connectivity,
interoperability and adaptability, with the potential
to result in lower transaction costs and end-to-end
IP improvements for all.
We are offering a limited number of free passes to
three groups to encourage participation and widespread
access to the expert IPv6 knowledge on offer at the
Coalition Summit for IPv6.
US military employees
US federal government employees, and
Government employees of Coalition Partners in the broadest sense.
If you are in one of these three groups you can get a code to register for the Summit at no cost.
To take advantage of this offer you will need to register
soon, as this offer for free passes will be closed
out before the end of April. Feel free to write me
at firstname.lastname@example.org and tell me what you are doing
in the area of IPv6, and which free pass category
you are in. If you qualify, I will gladly send you
the registration code. Government contractors are
not eligible for this offer (which is meant for direct
government employees), but the regular registration
is still very inexpensive, and your participation
In this issue of 6Sense we have an articles from
William Ivancic of NASA on the IPv6-based Global Aeronautical
Network, from Chris Buerger of Ixia on baseline IPv6
performance testing, from Bill Kine of Spirent on
multicast communication, from Salah al-Buraiky of
Saudi Aramco on the “Beyond Connectivity Services”
mindset, from Tim Le Master of Juniper, Wanda Newman
and Neal Katz of Global Crossing and Tim Winker of
Northrop Grumman on how their team creates IPv6 connectivity
and service (they will be doing this at the Summit),
from Alex Ramia of Panasonic on how v6 is more than
just another numbering system, and my article on the
need to appoint a federal IPv6 leader, preferably
soon. I look forward to meeting you at the Summit.
Please do register and be part of making IP history!

NASA Seeks Input Regarding IPv6-Based Global Aeronautical Network
By William D. Ivancic
Senior Research Engineer, NASA Glenn Research Center
The National Aeronautics and Space Administration
(NASA) is performing research and development under
the Airspace Systems Program to enable major increases
in the capacity, mobility and security of the air
transportation system. The Advanced CNS Architectures
and Systems Technologies Project (ACAST) Project within
this program is developing technologies intended to
improve the performance of the communications, navigation
and surveillance infrastructure in support of the
program’s goals. In addition, in 2004, NASA
initiated the Secure Aircraft System for Information
Flow (SASIF) project, an element of the Aviation Safety
Program (AvSP). SASIF is concerned with hardening
the radio data links and network communications, mainly
directed at hostile act intervention and protection.
NASA is working with other U.S. government agencies,
including the Department of Defense, Department of
Homeland Security, Department of Transportation, and
the Federal Aviation Administration, to define concepts
and requirements for the transformation of the National
Airspace System required to enable a tripling of growth
in system capacity. A key concept of this transformation
is the development of network-centric information
systems, which includes the airborne elements.
The NASA Glenn Networking Research Group, on behalf
of the ACAST and SASIF projects, has formulated a
list of requirements to ensure global interoperability
and deployment. Here, “global” implies
interoperability of all elements including network
security, whereas “deployment” implies
affordability and readily available technologies (i.e.,
technologies that will be available in the next few
The Beyond Connectivity Services Mindset
M. S. Al-Buraiky
Data Network Engineer, Communication Solutions Engineering
The Internet protocol (IP) is a minimalist
protocol that provides simple universal connectivity.
Its main function is to provide efficient and seamless
end-to-end datagram delivery. The power of IP and
its sphere of applicability can be greatly extended
by enabling the use of a more generic host model and
enabling the use of delivery models with more specific
guarantees in certain aspects.
The capabilities resulting from extending the network
layer functions can be collectively termed as Beyond
Connectivity Services (BCS). This includes IP multicast,
IP security, IP mobility and IP QoS. Multicast extends
efficient end-to-end datagram delivery to multi-end-to-multi-end
efficient delivery. IP mobility waives static location
as a condition for seamless datagram delivery. QoS
provides performance guarantees to the delivery process.
IP security provides confidentiality and authenticity
guarantees to the delivery. Those advanced (beyond
basic connectivity) IP features are generic services
that the network layer can offer to any upper layer
The current incarnation of the Internet protocol,
IPv4, wasn’t born with those capabilities. They
were back-fitted onto it at different stage of its
lifetime. They are now widely available on many platforms
and in many networks but there are serious limitations
in deploying and benefiting from them. Those limitations
stem from the limited address space of IPv4, its relatively
rigid mechanism for supporting options and its large
installed base, which limit the freedom protocol designers
have in mandating them and in changing the base protocol
specifications to optimally accommodate them. Today’s
Internet is largely a unicast network with no mobility
support, no QoS support and with mostly insecure protocols.
The IPv6 vision regarding BCS capabilities is that
they should be scalable, flexibly applicable and mandatory.
Scalability means that IPv6 is designed to support
those functionalities Internet-wide and not only within
enterprise networks. Flexible applicability means
that IPv6 should provide much more flexibility in
combining those functions together and in using them
with other protocols. Security shouldn’t be
a hindrance to providing QoS or multicast, for example...

Lead, Follow, or Lose the Great Game: Why We Must Choose a US IPv6 Leader
CEO, IPv6 Summit, Inc.
IPv6 can be the basis either for
the US to become more deeply interwoven with its military
allies and key trading partners and pay for its physical
imports with data flowing via our world-class end-to-end
networks, or to become more isolated from the rest
of the world, with less and less that other advanced
nations need or want. The US has gone from being a
net exporter of virtually every major category to
being a net importer of food, goods, capital, and
high technology in 2005, even as the dollar heads
towards the currency equivalent of being de-listed
as the world’s reserve currency. Federal investment
in IPv4 leadership has enabled us to be a net exporter
of data, media, and services, but if the US does not
win the game for IPv6 leadership, we put those exports
at risk as well. Must we ask, “Who lost the
Internet?” in years to come?
The choice of winning or losing IPv6 is in the hands
of a few hundred federal government officials who
decide whether and how to collaborate with the IPv6
leaders of key US allies including Japan, Korea, and
Germany, as well as multinational alliances like NATO,
the European Defense Force, and the European Commission.
All these powerful entities will be sending representatives
to the Coalition Summit for IPv6 to meet with their
counterparts from the United States federal government,
and with each other. The question that the US federal
government needs to answer is, “Who speaks for
IPv6 in the US?”...
Dream Team Supplies IPv6 Connectivity and Service
At Coalition Summit for IPv6 in May
Column contributed by Tim Le Master of Juniper Networks, Wanda Newman and Neal Katz of Global Crossing, and Tim Winter of Northrop Grumman.
The combined resources and capabilities
of Juniper Networks, Global Crossing and Northrop
Grumman have recently joined forces to provide IPv6
connectivity and services to the Coalition Summit
for IPv6, being held May 23-26 in Reston, VA.
This is the fifth show in the increasingly successful
IPv6 Summit series of events. The May event promises
to be better than ever.
Over 25 booths will be connected via IPv6 to the
Juniper Networks, Inc. Router that supports IPv6 as
well as dual stack IPv4 and IPv6 operations. Global
Crossing will provide Wide Area Network connectivity
for the v6 services so that remote facilities can
be connected to the show for testing and demonstrations.
Northrop Grumman will provide integration services
and ensure that connectivity between booths and routing
equipment is functional.
IPv6 is the next-generation networking protocol that
will eventually replace Internet Protocol Version
Multicast Communications - Supporting Shared Applications
Product Manager, Spirent Communications
There are three fundamental methods for transmitting
data over an IP network: unicast, broadcast and multicast.
Unicast traffic is sent to a particular destination
such as a host computer, web server or a particular
end user. Broadcast traffic is forwarded to all users
of the network. Multicast traffic is delivered to
a specific subset of the network’s users. For
example, an entire department, workgroup or site may
share information by using multicast data transmissions.
Both unicast and broadcast traffic types are easy
for networks to implement; data packets will either
be delivered to a single unique destination, or they
will be propagated throughout the entire network for
all end users. Supporting multicast traffic is considerably
more complex because the participants must first be
identified, and then traffic must be sent to their
specific locations. The network must also refrain
from sending traffic to any unnecessary destinations
in order to avoid wasting valuable bandwidth.
Large network operators are extremely concerned about
the effects of multicast traffic on their networks.
Network operators do not typically support broadcast
traffic (no messages need to be delivered to all users).
However, multicast traffic is increasing over the
Internet. Applications such as data casting (news,
stock tickers, etc.), video and audio transmissions,
and training seminars (also called webinars) all depend
upon multicast technology. These applications require
the network to successfully deliver identical packets
to a large number of receivers. These data packets
often must be replicated at an exponential rate –
the resulting bandwidth requirements and routing overhead
associated with these applications can be quite daunting.
Multicast communications exist for one sole purpose
– to conserve bandwidth...
v6: More Than Just Another Numbering System
Invented out of the necessity to communicate more efficiently. Expanded to
include the greater knowledge of the world. Named the “World Wide Web.”
Know affectionately as the “world wide wait.”
The WWW took off faster than any other communication technology; its global
embrace is now demanded by all modern consumers. We use this medium to
describe our companies’ abilities, services and hours of operation.
Consumers use the medium to schedule appointments, pay bills, review medical
records, play games, date, listen to music, watch movies, gather news and now
pay taxes. The Web is as entrenched in our day-to-day lives as the ever
present PSTN and mobile phone.
When the skin of the Web is peeled back we find a clogged network, patched routes,
stray packets, kluged numbering, hijacked consumers, security holes, etc., etc.
While this worked well enough for the pioneers of the technology, it falls far
short of a consumer friendly, reliable network that’s as easy to us as the PSTN...
Baseline IPv6 performance testing with IxChariot
and its set of well-documented benefits (see
Ixia's IPv6 White Paper)
have driven an increasing number
of operating system and network equipment vendors
to offer IPv6 support in their product lines that
previously supported only IPv4. Today, market segments
such as National Research Networks (NRNs) and connected
university campuses, federal, and government organizations
have deployed nationwide IPv6 networks. In addition,
engineering organizations working on IPv6 applications
or appliances, as well as service providers, require
IPv6 capabilities in new product acquisitions...
