How Do We Finally Get to IPv6?

James Wong

2

IPv6 Adoption Challenges

Large Investment in current IPv4 Infrastructure Older PCs, Laptops & Internet Devices etc Operating Systems like Windows Vista, XP, 98, etc to the ‘mere mortals’ Common Applications like Skype, WLM, etc..

The Internet is still very much IPv4

Lack of IPv6 Skills

Uncertainty of Market Demand

Lack of IPv6 Products and Solutions

3

IPv6 requires a full IPv6 chain of communication From End Devices / Clients (desktop, laptop, game device, smartphone) To Service Providers (Internet Service Providers, Mobile Network Operators) To Enterprise / Content Providers

Challenges

No backwards compatibility

If any of the three migrates before the other two, the communication is broken!

Least we forget….

Definition : Migration is the act of people moving from one place to another.

Migration?

Definition : To exist together at the same time or in the same place

Initial Plans

made for IPv6

IPv4 address runs out : Feb 2011. Effort to move to

IPv6 on: ISP to provide IPv6 over their IPv4

network, moving to using private addresses, making

legacy IPv4 services available to IPv6 users,

etc..

with network slowly migrating to support dual stack, it is necessary to take care of the issue of backward compatibility. Technologies like NAT64’/ DNS64 to provide bridging for IPv6 to access IPv4. 6rd/ds-lite/dualstack is technologies to facilitates deployment of IPv6, as well as IPv4 to users at the same time.Coexist of IPv4 and IPv6!

With possibly mass deployment of dual – stack via either or all 6rd/ds-lite/ dual-stack/6to4/sam/etc..

NAt64/dns64 to bridge ipv6 to ipv4, coexistence will be there until most internet or

services are moved towards ipv6. Believe this will continue for a while.

The secret to seamless IPv6 transition?

There isn’t one… no panacea… no one solution fits all

Each solution has its own pros & cons

Summary

IPv4 address depletion, IPv6 is a must Challenges for compatibility issues Technologies like 6rd, DS-Lite and even Dual-Stack is to

facilitates IPv6 deployment Feature concurrency for flexibility in deploying IPv6

ISP: flexibility to roll out service when needed Enterprise: flexibility to deploy and migrate to IPv6, keeping backward

compatibility to existing IPv4 network/services

Graceful HA failover – no interruption to users when network failover

Cost effective, High performance system

What’s In The IPv6 Promise Land?

• Abundant address space • Auto-configuration • Mobility • No More “NAT”ing• Embedded IP security • End-to-end communications • Extensibility for new features • New business opportunities • Enables the “Internet of Things,” which is a global internet

interconnecting everyday objects and dominated by machine-to-machine communications

• Improvements in automation, productivity, and efficiency • Strategic cost reduction • Engenders innovative business models in a variety of sectors
