Internet development in China
 Users experienced network security problems
Internet development in China
 Major Issues:
Scalability
 E.g. China Telecom is already the #1 ISP in the world,
how they grow in the next phase
Trust and Security
Mobility – ID/Loc separation
Control, Management and Business Model
 90% bandwidth occupied soon after the bandwidth is
upgraded (e.g. a guy was watched in Nanjing
downloaded movies that he could not watch in his lifetime)
 90+% revenue comes from 10-% users, then how to
provide QoS for those 10-% VIPs who paid most
The Green Internet：IT industry consumes 7-8% of
energy in China
How to extend Internet to people in the countryside
Internet development in China
 Questions from fast growing Internet
industry in China to academics
 What’s the Future Internet and how they
do in the next phase?
Huawei worries:
Huawei is growing fast but there is no direction
for the future, then Huawei has to keep a
competitor so that it could be #2 then follow
When Nortel dying, Huawei tried to save it but
failed.
If Cisco dies in the next decade, whom Huawei
could follow ?
Could academy provides them future R&D
directions in Future Internet ?
Research Networks in China
 CERNET: China Education and Research Network
 1994-, Managed by MOE, Nation wide backbone
 2000+ Universities and institutes, over 20 Millions users
 2004-, CNGI-CERNET2 (Native IPv6 Backbone)
 CSTNET: China Science and Technology Network
 1994, Managed by CAS, Nation wide connections
 100+ Research institutes, Users over 1 Million
 2000- NSFCNET (IPv4/IPv6)
 2003- CNGI (China Next Generation Internet, including IPv6
backbone, campus network, and R&D). CERNET2 is the
largest IPv6 network in China and the world
 3TNET (a testbed for Terabit optical, Terabit WDM, Terabit
Router + interactive TV), now is announced on July 31 2009
as NGB (not NGN or NGI, it’s Next Generation Broadcasting)

Phase1
 New Architectures
 Common technologies to Implement New Architectures,
e.g. Virtualization
 Common technologies to Support tested for New
Architecture
 International collabration with the US, Europe and JK.
 In the phase 2, the 13th Five-year Plan period
(2016-2021)
 Implement a couple of New Architectures by equipments
 A tested to run the new architectures.
Conclusion
 The Internet development in China is fast and we
also met many problems. The IT industry hope the
academy could provide them future directions
 CNGI, a major testbed in China
 Introduction to existing FI related projects in China:
fundamental research, R&D, Industry oriented
 The Future Internet is being considered in future
projects (2011-2021)
