3 The World is Talking About IPv6 Operator is worrying about Industry is pushing IPv6 forward Government is powering IPv6 World IPv6 Day 391 websites certified organized by ISOC In 2001, Japan made a national strategy of IPv6 development In 2003,the Europe Union formally suggest all the members to should give full support to IPv6 development In 2006,US DoD start to deploy massive IPv6 network HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 3
4 The Key Driver is IPv4 Address Exhaustion We ve really reached the breaking point IPv4 Address Space Exhaustion IANA free pool has exhausted ( Feb 3, 2011) RIR exhaust: soon after ( Apr , the APNIC pool reached the Final /8 IPv4 address block) IPv4 Address Space 4.3B Explosive demand for Address Growth of broadband deployments ( >1 address in ONE home) Explosion of smart phones Machine to Machine Hugh Demand >57B Home Network >2B It's enough to do an experiment, the problem is the experiment never ended. ----Vint Cerf Unbalance Mobile Internet 5B M2M 50B HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential Page 4
5 The Request is Beyond Address Exhaustion IPv6 Growing :Abundant public address stimulate the creation of fantastic applications Windows 7 DirectAccess (transport IPv6 only) Windows 2008 Cluster (uses IPv6 link-local address ) Apple Airport (uses IPv6 Link-local address) 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.
