Status report: IPv6 development of Research

and Academic Community in China

APAN 2004EWC, HWU2004/01/29

Requirement for IPv6

• Population in Mainland China 1,200,000,000– Regardless on other usages, 1 IP per person, we need

• 72 Class A IP address• Only have less than 2 Class A equivalent now

• Higher bandwidth needed– 1 hour online (28.8Kbps) per person per day

• 1.68Tbps

• Storage requirement– 1MB homepage per person

• 1200TB

Next Generation Internet Plans and Projects in China

• NSFC: Networking and Information Security– 5 years Basic Research Project

• National High Technology Plan for IT– Lambda Networking and switching– IPv6 Networking, Middleware and Applications– IPv6 Router and Switching– IPv6 Mobil Communication

• Next Generation Research and Education Backbone in China– CERNET2: National Wide Backbone at 2.5G-10G– High Speed International Links 155M+
