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
