DESCRIPTION
Presentation during ION Belfast in the "IPv6 Success Stories: Network Operators Tell All!" session from Ian Farrer from Deutsche Telekom AG. In this session, we invite network operators to share their IPv6 success stories and lessons learned along the way that can help other managers of networks deploy IPv6. How did they do it? What technical, organizational, and political challenges did they face? Attendees will gain vital insight as network operators lay out the stages for IPv6 implementation—creating the business case for management buy-in, initiating a planning process, flipping the switch, and, finally, gathering measurements and proving success.

REASONS FOR IPV6 – PUSH OR PULL? THE ‘USUAL’ JUSTIFICATIONS
§ We’re out of v4 addresses!
§ So’s RIPE/ARIN/APNIC….
§ Customers are demanding v6!
§ Look at the new services we can build!

If you already identified a push or a pull, (hopefully) you’re acting on it
. . .So, what if you have neither?
If not, by the time one appears, it’ll already be too late to act on it

STEP 1 MAKE THE COMMITMENT TO IPV6 ….
§ The world sees this as a problem for the ‘Network guys’, so as a network guy, you might as well accept it and start working on the solution (because if you’re not ready when it’s needed, it WILL be your fault!)
§ If you wait for the business case to appear, you’re going to miss the boat…
§ So, build an IPv6 submarine project § There are A LOT of free resources, training, requirements
and expertise out there. Getting yourself ready doesn’t need to be expensive

STEP 2 GET GOING …
§ Get IPv6 in the office or on your test environment
§ REAL IPv6 with real a real public address allocation!
§ Give your engineers a chance to work and play with v6
§ This bit is important – these guys need to evangelize v6 to the other techies. They’ve got to love it themselves!

Get your techies hands
dirty with v6!

STEP 3 BUILD A LAB…. § A good IPv6 Test Lab will be one of your most valuable assets
§ If you’re going to put IPv6 on to your existing network infrastructure, then use whatever
test equipment that you already have.
§ If you’re going to live in a dual-stack world, test in one!
§ The lab must be as comprehensive and complete as you can make it
§ Model your existing network
§ Test what you plan to deploy
§ Getting a response to a ‘ping6’ across a back to back link does not constitute an
exhaustive test plan!
§ When you’ve got it ready, use the lab as part of your internal marketing ….
§ à Showing people how it works is worth 20 meetings telling people how
it’s going to work

§ You can only break this cycle by getting IPv6 deployed onto your live network § Fortunately, networking infrastructure is comparatively the easiest part § Most of your networking equipment has probably supported v6 for a long time § If you don’t know what you need, documents like RIPE554 ‘Requirements for IPv6 in
ICT Equipment’ are there to help you § There is a lot of experience about now. You’re already out of the early adopter phase…
§ The bigger challenges that you may find here are: § Dual-stack v4/v6 interworking – get on top of this, as you’ll be here for a while § Operating and maintaining the network § Network Security
STEP 4 BREAKING THE CHICKEN AND EGG….
§ Why should I get my service ready for IPv6 when your network isn’t ready?
This is where you need your v6 evangelists from step 2 above …

§ Once you’ve got your network infrastructure ready, you’re in a pretty strong position
§ You now have the skills and experience to lead this § Work with the service owners to understand what their service does and
how they work § If new hardware/software/connectivity etc. are being purchased provide
support for creating IPv6 requirements
STEP 5 NEVER TOUCH A RUNNING SYSTEM… But if it’s going to be upgraded or replaced, then don’t let it stay v4 only!
This step is the long slog – it may well take years to complete (due to refresh cycles), but once the right skills and process are in place,
it’ll get there!

§ If you haven’t found him yet, he probably doesn’t exist…
§ But this can’t be an excuse for inaction
§ The world outside is changing rapidly – the amount of v6 connected customers is growing daily (20% in the RIPE Region now)
• Even if you don’t have a business case, you can still get your business ready
