Elections are a way to have a new beginning, to reflect
on what has come before, fix the errors, and aim to
achieve more. Users also have a kind of election when
they chose to use a new technology, and when they
start to use a newer technology. IPv6 is starting
its campaign, and, unlike the last election, the outcome
is known in advance: in the future, IPv6 will be the
primary Internet protocol for the vast majority of
users, uses, and Internet traffic.
In political campaigns, the best positions go to people
who were either among the first to sign on, thus having
a better chance to be part of an inner circle or brain
trust, or made the biggest contribution, either
through money, or by adding value through great advice.
Technology versions work similarly: the big benefits
often accrue to those who learn and adapt new versions
first, and to those who make the effort to endorse
the technology, and to make applications for it.
The US IPv6 Summit 2004, (http://www.usipv6.com),
now one month away, will take place in Reston, VA,
at the Hyatt Regency, and offers the opportunity to
be part of an inner circle, to learn how to adapt
and adopt IPv6, to have your vote counted by showing
up, and to see what applications opportunities exist.
The Dept. of Defense IPv6 Transition Office, the only
agency of the US government to have the funding, the
responsibility, and the context of a mandate with
a deadline to move to IPv6, will give a greater quantity
and variety of talks in one place on one day as ever
before. There will be no better time and place to
get the complete picture of how the DoD and the US
government (which will follow the lead) intend to
make the most of the incredible opportunity IPv6 offers.

In our last issue we presented the biographies of
keynote speakers Vinton Cerf and John Osterholz. We
are now proud to present the bio of Dr. Charles
(Chuck) Lynch, Chief of the Dept. of Defense IPv6
Transition Office. Dr. Chuck Lynch is the Chief of
the DoD IPv6 Transition Office which is responsible
for providing overall coordination, common engineering
solutions, and technical guidance across DOD to support
an integrated and coherent transition to IPv6.
Dr. Lynch received a BS in Engineering Mechanics from
the U.S. Air Force Academy in 1984, an MS in Systems
Management from the University of Southern California
in 1987, and a Ph.D. in Information Technology Engineering
from George Mason University in 2000. His academic
research was in the integration of unprecedented complex
He served as a regular officer in the U.S. Air Force
working space and missile programs at both the system
program office and headquarters staff levels. After
separating from the Air Force, he worked as a contractor
on the Strategic Defense Initiative and the International
Space Station programs. He joined the Defense Information
Systems Agency (DISA) in 1994 where he worked as a
network engineer on global systems and as architect
for next generation communications systems.
Leadership for Engineering & Integration IPv6
Grumman IT, TASC
The transformation of communications for the US
Government has started. The next generation of
communications - involving satellites, wireless and
terrestrial systems - is currently being implemented
and their concept of operations is awaiting IPv6 capabilities.
The need for improved protocols and capabilities is
critical for providing essential communications to
the future war-fighter and enabler. IPv6 will become
a critical instrument of their arsenals - providing
the mechanism for timely and secure communications
in a net-centric environment.
Internet Protocol Version 6 enables war-fighting
capability by increasing the flow of information
into every aspect of DOD and federal communications
from the largest command and control "system
of systems", to ships, aircraft, satellites,
weapons and tools, and even down to the individual
foot soldier. Many do not appreciate the magnitude
of this integration; most compare the IPv6 implementation
to that of Y2K preparations or simply state it is
just "the implementation of a dual stack or tunnel
brokers." Both undervalue the magnitude of the
benefits and risks associated with dynamic change.
IPv6 brings added security capabilities, enterprise-to-enterprise
interoperability, standardization, flexibility, common
interfaces, rapid deployments, and plug-and-play architectures
- all critically needed by our mobile military.
The need for methodology and structure to transition
is critical. A detailed methodology and proven
process must be implemented and followed across the
DOD and federal communities. Northrop Grumman Information
Technology, TASC has successfully integrated critical
systems across the intelligence, commercial, and DOD
communities. It is the System Engineering & Integration
(SE&I) leader for billions of dollars of US Government
assets, from Transformational Communications space
programs to Homeland Defense networks, Intelligence
networks, surveillance and reconnaissance platforms,
and even the White House. We start by establishing
strategic rules of the road such as:
Premium Services over IPv6
Dr. Lawrence G. Roberts
many carriers have concluded that interactive video
does not work well enough over IPv4 networks to be
functional. In many cases VoIP is also less than the
quality we expect. As broadband access, WiFi, and
3G phone service expand, these services are needed.
The reason they do not work well is that simple Class
of Service (CoS) marking (DiffServ) is not capable
of supporting a larger number of premium service calls
than the circuit can support at the same time without
discarding packets randomly from all of the calls.
For example, if a DSL circuit can support 3 video
calls and a fourth is requested, since they all have
the same priority, they all will experience random
discards of about 25% of their packets. This problem
can be fixed with IPv6, using a newly approved TIA
QoS signaling protocol.
The basic problem with premium services is that the
user either wants good service (all packets delivered
in a timely fashion) or he expects the call to be
blocked. The Internet has mainly had to operate with
TCP file transfer in the past, where a slowdown was
acceptable if the network became overloaded. But with
premium services, the call needs to be complete and
operate at full rate. Slow delivery of real-time data
creates a noise burst, and 25% noise is intolerable.
Thus, a method is required where the network can accept
or reject new calls depending on the capacity available.
This is an end-to-end network function and the network
must accept or reject calls or flows, not just packets,
as is the practice today. The new feature of IPv6
is a flow label that tells the routers these packets
are part of one flow. When this feature is combined
with a signaling protocol that can request a rate,
delay variance, and give precedence, then the network
can look at the current load and accept or reject
new flows. This is what the new TIA QoS signaling
protocol accomplishes. It allows the network to control
the premium service load, allowing or rejecting new
real-time flows. Using the precedence field, emergency
calls can still get through. For calls of the same
precedence, ongoing calls are not impacted by new
call requests. For more information on the protocol,
an IETF RFC draft is available at http://www.packet.cc/IPv6Q-IETF-2A.htm.
Historically, signaling protocols were out-of-band
and were processed in software. This resulted in very
limited performance and long setup times. In the past,
we started with SS-7 for the telephone network, went
forward with ATM signaling, and now use RSVP and LDP
for MPLS. All these protocols overload the software
and are not suitable for real-time setup in IP. However,
the IPv6 flow label and the TIA QoS signaling option
are designed to be processed in hardware, thus there
is no setup delay and no call setup overload. Calls
can be processed at line rate with virtually no increase
in the processing requirements. This is because the
signaling option only needs to be processed for each
flow, not each packet. Thus the increase in processing
is typically less than 1%. This allows premium services,
like video conferencing, to be set up across an IPv6
network and supported with near optimum quality, even
when mixed with all other data services.

The IPv6 Business Case
Silvia Hagen, Owner and CEO of Sunny Connection AG
This article discusses what IPv6 means for your business.
Should you invest in IPv6? If yes, when is a good
time to do it? How can you plan for IPv6 in order
to make your transition a smooth and cost-effective
Obviously, when you introduce IPv6 into a network,
cost will initially rise. You have to educate your
IT staff on IPv6, you have to build test beds that
let you test IPv6 related issues, and you also have
the costs of implementation.
And what is your return on investment? Why should
you invest in IPv6, while you have a running IPv4
network? There are many heated discussions in this
area, and it is important to ask the right questions
in order to get meaningful answers.
There are some important facts that should be noted:
IPv6 is inevitable in the long term.
Supporting IPv6 will soon be a minimum requirement
for hardware and application vendors.
If you plan for IPv6 early you will save lots
of money and many headaches.
This can be compared to any situation where you have
to introduce a new technology into your network. What
was the business case for introducing NAT? What was
the business case for your whole IPv4-based infrastructure?
What was the business case for upgrading servers to
the latest version?
An infrastructure does not create a business case
in itself. You need an infrastructure in order to
be able to use and run applications and services which
create a business case for your company. So you have
to invest in your infrastructure, because you need
a well developed and state-of-the-art infrastructure
as a foundation for efficient business processes.
You cannot use the newest and coolest applications,
if your server runs an old-fashioned version of the
operating system. You cannot use the newest and coolest
applications and services that build on the advanced
features of IPv6, while you are still running IPv4.
IPv6 Transition and Information Assurance - Going
Forward without Stepping Back
Ken Renard, Chief Scientist, WareOnEarth Communications
Today's business and government operations are increasingly
net-centric and face mounting difficulties in defending
and improving vital networks. To meet the challenge,
network leaders are laying a sound, future-proof foundation
with the move to IPv6.
IPv6 delivers many improvements but from a security
standpoint IPv4 and IPv6 may be nearly identical -
mandated IPsec being the only obvious difference.
So if these two versions of IP are nearly identical
security-wise there shouldn't be any problems, right?
Well, some insidious "gotchas" can ambush
your network if you don't target them when considering
IPv6 and your existing security tools, policies, and
10 Million New Jobs from IPv6: The Case for US Government
Alex Lightman, Chairman, US IPv6 Summit 2004
President George W. Bush and his administration have
turned their attention away from winning re-election
to preparing for the next four years, and to the judgment
of history. Of all the slings and arrows from John
Kerry, the one that had to sting the most was Kerrys
America cannot afford a President whos
the first to lose jobs since Herbert Hoover in the
Great Depression. As evidenced by the election
returns on Nov. 3, most voters understood that there
are down turns, especially after the boom in the 90s,
and that 9/11s trillion dollar loss cost jobs
as well, but all eyes will be watching to see whether
and how the Bush administration creates jobs
and especially how many.
John Kerry set the target for the next four years:
to create ten million new jobs. Just like winning
the popular vote in 2004 has ended the legitimacy
debate, so, too, would generating 10 million jobs
go a long way to resolving the economics doubts of
over 55 million people, and serve as a powerful track
record for the Republican controlled House and Senate,
as well as the Republican case for yet another presidency
in the 2008 election. The US government should publicly
embrace Kerrys 10 million job goal.
Since this is 6Sense, the newsletter for IPv6, it
might come as no surprise that we believe that IPv6
is the single best place to invest, the highest leverage,
the biggest bang for the federal buck, to create those
10 million new jobs. This article will argue the case
from several angles, after some context. Currently,
the US government has, to date, budgeted funds (roughly
$10 million annually) for Dept. of Defenses
IPv6 Transition Office (DITO), with additional funds
being ramped up by the individual branches of the
services. The Dept. of Homeland Security is the only
other US government (or state or local) agency to
mandate IPv6, but does not have a specific budget
for that, so DoD is the clear leader for IPv6, and
increasingly sets the pace for the rest of the world,
a pace that will accelerate after the DoD/DITO's ten
presentations at the upcoming US IPv6 Summit in December.
DITO sets the definitions and criteria for compliance,
though, thereby directly impacting over $25 billion
in IT purchases that must include support for IPv6,
and thus it is vital for companies seeking to sell
IT to the U.S. government to understand and communicate
