China Science and Technology Network (CSTNet) is one of the indispensable basic foundations

for the researches of CAS, in pastcurrent, and future.

CSTNet• The earliest Internet in China• Objectives of CSTNet:

– Establishing a nation-wide advanced network infrastructure to connect all of the scientific and technical community in China using the up-to-date techniques

– Providing network services for S&T researches : connection, operation, management, and supporting…..

History of CSTNet• Project NCFC (1989.11-1993.3)

– National Computing and Networking Facility of China Supported by World Bank Loan + State Planning Commission

• Project CASnet (1993.3-1995.4)– 123 Research Institutes, 12 CAS Branches, 25 Cities– Satellite, Microwave, DDN, X.25– a scientific oriented national network– named “China Science and Technology Network”

(CSTNet).• The China's top domain name (CN) servers was

set up in CSTNet.(1994.5.21)

Topological of CSTNet (current)

• Backbone : 10Gbps• WAN:2.5G/155M• MAN:1Gbps• Cover +23 provinces

• End user +1 million, hundreds institutes in/outside of CAS connected

• Connecting with China Tel, CNC, NIX, CERNET,UNICOM, etc

Current Status Of CSTNET Internet Connections

155M

Advanced Network Services

• NOC service• Video Conference• Web e-mail

service• CSTNET-CERT• VOIP

CSTNET NOC

CERT for CSTNet

• Provide technical advice• Coordinate response to security incidents

and events• Work with other security experts to identify

solutions to security problems• Disseminate information to the customs• Publish technical documents• Present training courses

IPv6 Activities based on CSTNet

• CNGI (China Next Generation Internet CNGI) project by NDRC, 2003– Multi-government department’s support– Multi-service provider’s participation– Biggest IPv6 deployment in China

• The total fund for CNGI project is 1.4 billion RMB.

• China CSTNet / China Netcom Company (CNC) established 7 Giga-PoPs and the network management center

• CSTNet connecting 100 research institutes

Int’l network cooperations

GLORIAD Grand Opening CeremonyCAS Headquarter Jan.12, 2004

• In general, most Internet servicesprovided by CSTNet in good quality

• But now, new requirements to high broad bandwidth from researches and engineering more and more

• Internet or CSTNet satisfying them ???What kind new requirement ???

• Italy, Japan-China cosmic ray observatories in Tibet.

• 300TB raw data per year.

• Data transferred to IHEP and processed with 400 CPUs.

• Rec. data accessible by collaborators.

1, Cosmic Ray Observatories in YBJ, Tibet--- YBJ-ARGO/ASγ

YBJ-ARGO

• Established a 8Mb/s link from Tibet to Beijing in March 2005, by CNIC of CAS. Upgraded to 155Mb/s in March 2006. – Stopped bringing tapes half year ago.

• Building a computing system based on LCG, collaboration of IHEP of CAS, CNIC of CAS, INFN of Italy , EU-China Grid application under EU FP6.

2, LCG Tier-1/2 Between IHEP and IN2P3

• to build a LCG Tier-1/2 node connection between IN2P3, Fr and IHEP, China

• Institute of High Energy Physics of CAS

• CNIC providing support and working together with IHEP

3, BEPCII/BESIII

BEPC: Beijing Electron Positron Collider by IHEP of CAS• Started in 1989• 2~5GeV/C• Being upgraded toDual-Ring, (3~10)×1032 cm-2s-1

• 27 Universities andInstitutes from US, UK, Japan, Koreaand China.

BESIII Computing

• CPU：>1000 P-IV/3GHz CPU for data production/reconstruction

and physics analysis• Storage：more than 3PB in 5 years. • Network：high speed network for

international/domestic communications

4, VLBI sites

4, 4, ChinaChina --Japan Collaboration Japan Collaboration fofor r VLBIVLBI • The first China-Japan VLBI experiment was

performed with Shanghai-Kashima Baseline in Sep. 1985

• Kashima is one of the most precisely determined positions in Japan : used as the reference point to establish Japan Geodetic Datum 2000 (JGD2000)

• Seshan (Shanghai) is the most precisely determined position in China

• Chinese Academy of Sciences and NICT are both active members of IVS*

Features of “big sciences”

• Some common features of “Big Science” or “Big Engineer” in network:– Mass data transfer– In time and real time– Burst of traffic– No interrupt, and high quality– Control enable by end-user– Cross multi-region / international, multi-institute, and

multi-network– Security …

New technological solutions for “Big S&E”

• Broad bandwidth necessary and• Bandwidth distributed on demand,

dynamical and coordinate• IP protocol and router technology not

necessary• TCP protocol modification• Network management faced to multi-

service
