Internet development in China • Almost years history from 1994-2008 • Internet users: 253 Millions • Growth 56.2% per year, from 162M to 253M • IPv4 Addresses: 158 Millions • Growth 33.7% per year, 5.9% in world • International links:493,729Mbps • Growth 58.1% per year • Exchange Points:200G+(BJ,SH,GZ)
Challenges of Current Internet • IPv4 Internet: 80% traffic of information infrastructure in world • Challenges of current Internet • Scale:from connecting computers to another • Security:more trustiness • High performance:more fast of end-end performance • Real time:more timely • Mobile:mobile communication over Internet
NGI Development in the World • NGI Testbed have been connected together in the the world from 1998 • Internet2,Geant2,APAN/TEIN2,…… • NGI and IPv6 Standard Development • IETF • Industry is ready • CISCO, Juniper, Huawei • Microsoft, SUN • Future Internet Research Project • GENI and FIND
