IPv6 and CNGI in China Jianping WU July 6, 2004

Contents What is the next generation Internet we needed IPv6 and its development CERNET update Next Generation Internet and IPv6 Activities in China CNGI Project CERNET2: one of backbone in CNGI

Internet in China Internet users in China: from 6.8 Millions to 78 Millions within 6 months IP Addresses: 32M 1A+233B+146C Backbone G DWDM+Router International links 20G Exchange Points > 30G BJ SH GZ Last Miles Ethernet WLAN ADSL CTV CDMA ISDN GPRS Dial-up Total Wireline Dial UpISDNBroadband 68M23.42M45.01M4.9M9.8M

What is the next generation Internet we needed Internet have been an important infrastructure today and still deploy very fast Major characteristics of next generation Internet: Large scale network: IPv6 address End to end high performance Security and trust network QOS control network Mobile There is not unify definition for next generation Internet but IPv6 should be an important part of NGI

Why is IPv6 needed? Much larger address space IPv6 Addresses: 3.4X10 38 Trust network: real IP address access Improved routing Route aggregation reduces the size of routing tables Simplified header reduces router processing loads Enhanced security and QoS Mandatory IPsec support all fully IPv6 compliant devices Improved support for mobile IP and mobile computing devices IP is everywhere Data, Voice, Audio and Video integration is a Reality Regional Registries apply a strict allocation control
