CERNET IPv4 Backbone
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

IPv4 Addresses will be finished in 2010 or 2011 69th IETF Meeting: large scale addressing and
routing Problem: 10,000M IP active addresses and 10M
Multi-homing IP addresses 70th IETF Meeting: IPv6
Problem: IPv6 Internet operation and management; transition from IPv4 to IPv6
71th IETF Meeting: IPTV 72th IETF Meeting: IPv6 Experiences from the Field
Internet Research in China First phase: 1994-1999
Internet enter China: construction and usage Begin internet research
Second phase: 1999-2004 Development on Internet IPv4/v6 Router Research on implementation of Internet
Third phase: 2004-? Ask why? How to improve current Internet better? Internet architecture and its theory
