As we head into our biggest IPv6 Summit event ever,
we would like to honor and thank the entire IPv6 community
for supporting us in this next major step in helping
the world transition to IPv6. We are just a couple
weeks out from the US
IPv6 Summit and Coalition
Summit for IPv6 2007, and attendance and sponsorship
are both at a record pace. This IPv6 Summit promises
to be the largest IPv6-focused event in America, and
will bring the best and brightest together March 26th
– 29th, 2007 in Reston, VA. With the participation
of NATO, international government agencies and industry,
you'll hear an outstanding line-up of speakers from
around the world talk about what benefits IPv6 will
bring to many of the problems that confront us today.
In addition, we are looking forward to all that our
sponsors have to offer and demonstrate, including
presentations by the prime Tier One telecoms on how
they can provide IPv6 connectivity for you–today!
We are also excited about the unveiling of the real-life
applications that are being developed for the IPv6
City of the Future project—we will have at least
one history making event for you to witness, and tell
your grandchildren about. The age of IPv6 is upon
us, and we believe this upcoming Summit event will
form a global arena for the smartest companies and
agencies to lead the race.
This month's 6Sense features some great
up-to-date information on IPv6 network transitions,
applications and business models. We begin with an
article from Shawn Khazzam, Senior Business Development
Manager at OPNET Technologies, discussing how network
design software will accelerate network migration
and mitigate associated risks. Stan Barber, Vice President
of NTT Communications, delivers some valuable information
on why it is critical for every organization to develop
a basic IPv6 migration strategy and begin experimentation
as soon as possible. Silvia Hagen, of Sunny Connection,
provides an interesting overview of the statistics
behind an ever expanding IPv6 business case, and considers
what the cost savings will be. BT Diamond IP Director,
Tim Rooney, offers their second installment on IP4-to-IPv6
transition strategies with a closer look at tunneling
technologies. Last, but certainly not least, Foundry
networks has provided a valuable white paper, written
by Val Oliva, who will also be speaking at the upcoming
Summit event. The paper illustrates why it has become
critical to focus not only on the network core during
migration, but to also ensure that edge devices and
services are up-to-speed.
We thank you for your participation, and look forward
to meeting you at the Summits—see you in Reston!

Ensuring a Successful IPv6 Transition with OPNET
Senior Business Development Manager, OPNET Technologies, Inc.
Over the past few years, organizations have been
anticipating the need to migrate their current IPv4
network infrastructure to IPv6. For many, the time
has finally arrived. The availability of IPv4 32-bit
network addresses is significantly constrained and,
as a result, the US Office of Management and Budget
has mandated that all government agencies be IPv6
compliant by June 2008. IPv6 offers an expanded IP
address space, as well as integrated security and
mobility, enhanced equipment auto-configuration, and
many other useful features.
According to numerous industry analysts, migration
to IPv6 is a major network transition that requires
considerable planning. Errors could result in costly
network outages, security gaps, and application performance
problems. A few of the questions that need to be addressed
when developing a strategy are:
- Do existing network devices support IPv6? If
not, can they be upgraded?
- How will existing legacy applications perform
- Will network capacity be adequate to support
migration to IPv6?
- How will operational integrity be maintained
during the incremental migration?
- How can network security and resiliency be ensured?
Getting Experience Using IPv6
Vice President, NTT Communications
As we all know, IPv6 has not been widely adopted
in the US for a myriad of reasons, which have been
recounted in various articles in 6Sense over the years.
There are many who now expect the US Government OMB
Mandate to drive more extensive IPv6 deployment. In
turn, this would increase the adoption of the protocol,
creating a dual-stack network with IPv6 operating
alongside the current IPv4 transport. A few continue
to insist that IPv6 is not useful enough to implement
and would prefer to see other alternatives. What those
alternatives might be remain diverse and uncoordinated,
so no widely supported consensus on an alternative
has arisen. As long as there is no consensus, IPv6
remains the only viable successor to IPv4.
However, IPv6 (like IPv4) is not a panacea. While
the standards work for IPv6 started well over a decade
ago, and the basic protocol has been stable for almost
a decade (RFC 2460 was published in 1998), there remains
concern about multihoming and the address allocation
plan currently being used by registries (ARIN, RIPE,
APNIC, etc.). The IETF and others are still working
on refinements to some of the new capabilities in
IPv6. This work may make others uneasy concerning
its real readiness. These activities center on Mobility,
QoS, use of the Flow label, handling of multi-addressable
hosts and such. None of these concerns make IPv6 unusable
for production traffic today, but this is important
work that will allow IPv6 networks to realize capabilities
that were not really available with IPv4. These issues
were highlighted in the recently circulated draft
profile for IPv6 in the US Government. However, NIST
acknowledges that the IPv6 standards are stable and
"operationally viable commercial implementations are
becoming available." See page ES-1 of that report
available at http://www.antd.nist.gov/usgv6-v1-draft.pdf.
The IPv6 Business Case
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 the time to do it? How can you plan for
IPv6 in order to make your transition a smooth and cost-effective one?
Obviously, when you introduce IPv6 into a network, costs 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, you have to create a strategy,
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?
A recent study conducted by the Department of Commerce (1) in conjunction
with the independent research group RTI International (2) examines the
costs and benefits associated with the transition from IPv4 to IPv6. The
study comes to the following conclusions:
For every dollar invested in IPv6
you can expect a $10 return in cost savings.
The cost for transition to IPv6 is estimated to be $1 billion per year,
so IPv6 creates a services market projected to be approximately $25 billion
over the next 25 years. The financial benefits of IPv6 transition are
expected to be $10 billion per year. Of each dollar invested in IPv6,
only about 8% is projected for the actual infrastructure upgrade and the
other 92% for leveraging the advantages of IPv6.
Making The Edge Ready for IPv6
By Val Oliva
Director of Product Management, Foundry Networks
While everyone focuses on making sure that the Core of the network
easily migrates to IPv6, it is critical to ensure that the Edge is also
ready for IPv6. For seamless migration to IPv6 at the Edge, network managers
must focus on some key fundamentals.
Network managers worldwide are contemplating their
migration strategy to seamlessly support IPv6. These
networks are located in the following areas:
- Federal and local governments, especially in the
United States of America (USA)
- Enterprise companies within Asia and Europe
- Service Providers across the globe
Although this list does not include Enterprise networks
in the USA, it is still important to understand the
“gotchas” for ensuring that the Edge can
migrate to IPv6. There are plenty of inherent benefits
to be gained from a move to IPv6, including a consistent
communication medium – IPv6 – used worldwide.
WHITE PAPER [44K PDF]
IPv4-to-IPv6 Transition Strategies: Tunneling Approaches
(Part 2 of 3)
Director, Product Management, BT Diamond IP
This article, excerpted from a white paper of the
same name, is being presented over three issues of
6Sense and reviews the three primary migration
technologies that can be used to transition from an
IPv4 network to an IPv6 network. In February's issue
we talked about Dual Stack. In this issue, we'll overview
Tunneling. Then, in the April issue, we will discuss
Translation. Click here to download our IPv6
Toolkit, which includes the full IPv4-to-IPv6
Transition Strategies white paper in addition to webinars
on IPv6 management.
When we discuss migration, we're referring to an initial state of
an IPv4-only network, which IPv6 nodes and networks are added to or overlaid
over time, resulting in an IPv6-only network, or, more likely, a predominantly
IPv6 network with continued IPv4 support.
A variety of tunneling technologies has been developed to support IPv4
over IPv6, as well as IPv6 over IPv4 tunneling. These technologies are
generally categorized as configured or automatic. Configured tunnels are
predefined, whereas automatic tunnels are created and torn down "on
the fly." We'll discuss these two tunnel types after reviewing
some tunneling basics.
