2. INDIANAUNIVERSITYINDIANAUNIVERSITY Spring 2001 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.

3. INDIANAUNIVERSITYINDIANAUNIVERSITY Spring 2001 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.
