Critical Factors

• Why do we need to deploy IPv6?

• What are the financial implications?– Of deploying IPv6

– Of not deploying IPv6

• What will be the effect on customers?

• When do we need to have IPv6 deployed?

Rationale for IPv6

• The growth of the Internet has been phenomenal and shows little signs of slowing!

• But the basic unifying protocol (IP) that links applications to IP networks is starting to show its age and hamper growth

• IPv6 builds on the success of today’s IPv4 protocol by solving fundamental problems

• IPv6 will be required, in the long term, to enable the continued expansion and evolution of the Internet.

Drivers and Timings

• Why an organisation needs IPv6– Commercial drivers

– Political drivers

– Technical drivers

• When will IPv6 be required– IPv4 address exhaustion (probably within the next 10 years)

– Migration to IPv6 Capable Operating Systems

– Devices support

Why - Commercial

• Strategic– Support future needs of customers

– Be ready to support future IPv6 migration

– Protect new infrastructure investment

– Ability to grow the network to support new services and opportunities

• IPv6 Cost savings– Private address management

– Network management

– Fault diagnosis

Longer-term savings!

– Migration costs

– Co-existence

– TrainingV

Why - Commercial

• IPv4 Address Exhaustion– Predictions range from 2008 –

2017

– Should assume that within 10 years you wont be able to get route-able IPv4 addresses

– Auditing of IPv4 allocations may become costly

– Global market place for route-able IPv4 addresses?

– Private IPv4 addressing limited to about 16 million.

Why - Political

• US Department of Defense mandate to migrate to IPv6 by 2008. Other US government agencies have been requested to follow suit.

• Japanese ISPs supporting IPv6 today. Incentives provided by government.

• South Korean governments mandating IPv6 migration.

• Big push to deploy IPv6 in China by end of 2006.

Why - Technical

• New Service Opportunities– Efficient & Secure IP Mobility

– Simpler Peer-to-peer applications development and deployment

• VoIP

• Network Gaming

• Easy for novice installation

– Remote Network Management

Why - Technical

• Ability to uniquely address Enterprise networks – particularly those that are geographically distributed.

• Potentially easier to re-number after mergers

• Internal enterprise security– protect revenue

When

• Dependent upon the factors that affect your business.– Market/customer intelligence

• Migration should take a number of years to be most cost effective.– including network/application trials

• Ensure no detrimental effect on existing business!

When - Transition

• Part of normal equipment upgrade plans– Significant percentage of network equipment is IPv6 capable

– BUT check for required features

– Transparent to customers

– Trials

• Operational Support Systems– May need significant migration time

• Personnel– Training and ‘on the job’ familiarisation

Be Prepared for a long period of Co-existence!!

When – Vendor Support

• Cisco

• Juniper

• Hitachi

• Ericsson

All have mature IPv6 offerings.

Can build operational Core networks now.

When – Applications

• Almost all Linux variants are IPv6 capable

• Microsoft XP has IPv6 stack and support for IE

• Microsoft Vista/Longhorn fully IPv6 capable – end of 2006

• Gaming devices– Sony

– Xbox

• Consumer devices
