What is TransPAC?

TransPAC is a cooperative project funded by the US NSF and the Japanese JST to provide a high-performance network connection between the Asia-Pacific and the United States science communities; and, to encourage the use of that network in the development of cooperative science.

From an engineering perspective, TransPAC has three components

1. The TransPAC circuit between Tokyo and Chicago, landing at the STAR TAP.

2. The equipment configuration at the Tokyo site (Tokyo XP)

3. The equipment configuration at the Chicago site (Chicago XP)

This talk focuses on current configurations, future plans for these three components and some applications.

Chicago XP: The Further Future

• Removal of Cisco LS1010

• cflowd data from Juniper would capture all data

• Less reliance on OC3mon machine

Scientific InstrumentsTrans-Pacific 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.
