IPv6 Development in China Congxiao Bao 2012-02-29

Internet population 0.644 IPv4 address per user China lacks 100M+ addresses in next 3 years China stated CNGI project in 2002 The IPv6 address allocation increased in 2011

CNGI project during 2002-2011 The major ISPs have participated in the CNGI project CNGI-CERNET2 is the most the active IPv6 network, the aggregated traffic exceeds 50 Gbps The IPv6 traffic is exchanged in CNGI-6IX. However, the traffic is only about 2 Gbps

New IPv6 action plan In Dec. 23, 2011, the Chinese government announced new IPv6 action plan The milestones are: 2012-2013 setup test bed (about 8M users) Finalize the IPv6 business model and transition plan 2014-2015 Large scale IPv6 deployment Ensure the intercommunication between IPv4 and IPv6
