The World is Talking About IPv6

Operator is worrying about…Operator is worrying about…

Industry is pushing IPv6 forward…

“World IPv6 Day”•391 websites certified •organized by ISOC

Government is powering IPv6 …

In 2006，US DoD

start to deploy massive IPv6 network

In 2003，the Europe Union

formally suggest all the members to should give full support to IPv6 development

In 2001, Japan

made a national strategy of IPv6 development


The Key Driver is IPv4 Address Exhaustion

■

IANA free pool has exhausted ( Feb 3, 2011)

■

RIR exhaust: soon after ( Apr. 15 2011, the APNIC pool reached the Final /8 IPv4 address block)

IPv4 Address Space

Mobile Internet

Home Network

IPv4 Address Space Exhaustion Explosive demand for Address ■

Growth of broadband deployments( >1 address in ONE home)

Explosion of smart phones■

Hugh Demand

“It's enough to do an experiment, the problem is the experiment never ended.“

----Vint Cerf


The Request is Beyond Address Exhaustion

IPv6 provides the possibility of having a Better Way of Life

Windows 2008 Cluster(uses IPv6 link-local address )

Apple Airport (uses IPv6 Link-local address)

Windows 7 DirectAccess (transport IPv6 only)

IPv6 Growing :Abundant public address stimulate the creation of fantastic applications

For Enterprise users ■

DirectAccess allows users to remotely connect to corporate network without a traditional VPN client configuration or application, gives users a seamless remote corporate connection.

For Residential Users ( also SME)■

Apple Airport makes it easy to connect to the Internet, print, and stream iTunes music to any room in the house — all wirelessly■

Windows 7 HomeGroup: simplify the sharing within your home network.

Network scenarios and address pressures vary by ISP. Thus there are multiple valid technologies or combinations of technologies for transition: dual stack、DS-Lite、6rd, and dual stack + NAT44,and so on.

Different CGN solutions fit different deployment scenarios

Huawei’s vision for IPv6 transition

Retain user experience for IPv4 applicationsRetain only one level of NAT between hosts and applicationsEnable end users to have certain policy control over CGN

Create Incentives for IPv6 adoptionEnd-to-End IPv6 Solution from CPE to backboneNative support for IPv6 to end user

Deploy Carrier Grade NAT (CGN) in service provider networksShare single IPv4 address among multiple users

Ensure IPv4 service continuity during transition period

Summary: IPv6, Action Now

IPv6 Mauritius, We already on the way!

Now this is not the end of the work to get IPv6 deployed.

It is not even the beginning of the end.

But it is, perhaps, the end of the beginning

Thank You！
