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

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
