TransPAC High-performance connectivity between
the US and the Asia-Pacific Region

Background
The TransPAC Project provides high-performance
network connectivity between the Asia-Pacific
Area and the United States for the purpose of
encouraging educational and scientific
collaboration among scientists and researchers in
these respective areas.
Specifically, TransPAC connects the Asia-Pacific
Advanced Network (APAN) to the US
high-performance infrastructure (Abilene, the
vBNS and fednets) and to other international
high-performance networks (Canarie, and EU
networks).

Background 2
The TransPAC Project is jointly funded by the US
National Science Foundation and the Japan Science
and Technology Corporation.
Indiana University provides technical and
administrative support for TransPAC in the US.
KDDI provides similar support for TransPAC in
Japan.

Previous TransPAC network
Prior to 15 October 2001, the TransPAC network
consisted of 155Mbps ATM service from Tokyo to
the STAR TAP in Chicago.

Current TransPAC network
On 15 October 2001, TransPAC was upgraded to
1.244Gbps. The new TransPAC network has dual
622Mbps connections from Tokyo to Seattle
(Pacific Wave Connection Point) and to Chicago
(StarLight Connection Point).

TransPAC Applications
The primary purpose of TransPAC is to provide
infrastructure to encourage scientific
partnerships between the US and AP areas. Some
examples are...

Telemicroscopy
Scientists at the Osaka University Research
Center for Ultra High Voltage Electron Microscopy
(UHVEM) and University of California San Diego
National Center for Microscopy and Imaging
Research (NCMIR) successfully use international
advanced research networks to couple the world's
largest and most powerful (3 million volt)
transmission electron microscope at UHVEM to a
remote-use computer pavilion set up at NCMIR.

Scientific InstrumentsThe Subaru Telescope,
Mauna Kea, Hawaii
During INET2000/iGrid 2000 the Subaru Telescope
in Hawaii was connected via a high-speed link to
the conference site in Yokohama, and
high-definition astronomical images were quickly
retrieved from the telescope. Real-time
interactive classes and discussions with
researchers also took place between Hawaii and
Yokohama via TransPAC using high-quality
multimedia communication tools.

ATLAS Grid Activities in Japan

• KEK and Univ. of Tokyo will jointly build a
  Tier-1 Center in Japan for ATLAS
• Technical Challenges
• High-latency WAN with Gigabit Network
• CPU farm with thousands of PCs
• Petabytes of storage with the CPU farm
• Maintenance and scalability issues
• Collaboration between physicists and computer
  scientists has started in July 2000
• Thanks to B.Segal, I.Foster et al.!
• The collaboration has yielded a first prototype
  of "Gfarm" toolkit

APEC Cooperation for Earthquake Simulation (ACES)

• International collaboration to study and model
  earthquakes in the A-P Region
• Participating countries Australia, China, Japan,
  and the U.S.
• Objectives
• Develop computational earthquake models for the
  region
• Assimilate new data into the models
• Foster the development of research infrastructure
• Foster collaboration between relevant research
  programs in the member countries

TransPAC and Grid activities
My role at this meeting is three-fold 1. To
discuss the TransPAC network infrastructure 2.
To express TransPAC support for grid computing
efforts and extend a personal offer of
assistance to researchers involved in grid
efforts in the AP area 3. To emphasize the
necessity of network expansion to meet the
requirements of these new scientific
experiments A couple examples.
18
Data Rates for Selected Projects
1 Data rates for these two instruments only.
A minimum of three are required for spatial
resolution.

To conclude...
To solve this bandwidth problem and meet the
needs of the scientific community, all of us
(networking professionals, scientists and
administrators) must work together. The
problems are large and will be upon us shortly.
