Next Generation Internet Activities in China

CERNET: IPv6 Test bed and 6 Bone in 1998 APAN-CN: 1999 MOU with UCAID:

– Draft with CERNET on March 2000– CERNET, CSTNET and NSFCNET on May 2000

Peer Connection Agreement with Abilene:CERNET on March 2000

Donations of International Connections to STAR TAP and APAN for three years free– 10M to STAR TAP from China CNC in March 2001– 10M to APAN from China Telecom in Sept. 2000

NSFCNET Project

Optical fiber and DWDM technology– 8X2.5/10G DWDM developed by China

– 400 km long-haul transmission system

High speed Internet backbone and research– connect 6 nodes using CISCO GSR OC48/OC192

– connect high speed LAN using GE at each nodes

– connect to CERNET and CSTNET

– IP QoS, IP Multicasting and IPv6 backbone

– Network management and measurement

Major applications– Distance learning and education, Digital libraries

– Earth information system, VOD, and Bio-medical

CERNET： Experiences and Demands

Bandwidth always is not enough for Educated and Research Network

Custom always needs new technology and app. Research and Education Network always tries new

technology and application Lambda Networking

– Nation Wide Backbone for Research and Education Network

– Regional Network and Metropolitan Network

– Campus Network

Need mature technologies for the above networks
