Asia Pacific Information Infrastructure

At APEC Summit2 in Bogor (1994), APII was introduced as a
cooperative framework of APEC member economies
- in response to G7’s GII, Clinton Admin’s NII etc.

At APEC TELMIN1 in Seoul (1995), the five objectives of APII
were defined
1) construction of information infrastructure
2) technological cooperation
3) free flow of information
4) human resources development
5) creation of policy and regulatory environment

APII Testbed Project, as a sub-policy for realization of APII,
was co-proposed by Korea and Japan at APEC TEL12
(Shanghai, 1995)

APII Testbed: Characteristics

Toward a major research network in AP region
A major actor in Asia for TEIN with GEANT, European counterpart
Stronger capacity, more interconnectivities are needed
>> Currently there is no unified system for management & operation

Changing focus
From testing interconnectivity and interoperability
To conducting joint R&Ds in various application services

Cooperation among APEC member economies
Korea, Japan, Singapore and US are the main partners
APII-CC(Korea) & APII-TC(Japan) play a leading role
>> Incentives are needed for inviting more partners


Cooperation Between EU and Asia
After the Cold War, the int’l society became tri-polar with US, Europe and Asia
>> In 1996, resulted in the establishment of the Asia-Europe Meeting (ASEM)

Political Idealism
Co-prosperity of Europe and Asia through TEIN
>> Int’l Organizations involved such as ASEM, APEC etc.
>> Inter-Governmental

Cooperation for Balanced Development
Not only Collaboration in Advanced IT-Research
But also Cooperation for Bridging Digital Divide

- Co-proposed by KR, SG and EC

TEIN EGM-1 (Seoul, Mar. 2001)
- Discussed how to launch TEIN

1st Generation of TEIN launched (5 Dec. 2001)

TEIN Initiative: Objectives
a) Contribute to enhancing exchanges and cooperation
between Asia and Europe through increased and more
effective information flows;
b) Enhance and diversify research exchanges and
cooperation between Asia and Europe;
c) Expand and diversify speedier and more powerful
telecommunication connections between Asia and
Europe
- Quoted from the ‘Concept Paper’ prepared by Korea in May
2000 for ASEM

Basic Capacity of the Link was set (12/2001):

SCR (Sustained Cell Rate) 2 Mbps

PCR (Peak Cell Rate) 4 Mbps
PCR can be increased up to 34 Mbps for the needs of
research activities
Basic Capacity was re-set (03/2002):

SCR (Sustained Cell Rate) 10 Mbps



WK08: 24 Feb - 2 March

Link capacity increased since 01 March 2002
from SCR 2Mbps/PCR 4Mbps, to 10Mbps/20Mbps

Traffic congestion consistently shows strong demand

Higher usage from Europe rather than from Asia
Further increase of capacity is needed

Future Scenario

KR-FR TEIN linkage will be upgraded to 34Mbps,
provided that the needed financial resources can be identified
by ASEM partners

Regarding intra-Asia connectivity, direct linkages will be
established between Korea and Malaysia
- MY will serve as a hub for the ASEAN members of ASEM

KR-US APII-TB/KREONet2 will be upgraded to 155Mbps

Unified plan for the entire Asia will be made jointly by MY
& KR
