[Status of NIHS Computer Network System (NIHS-NET)]

We described the development of National Institute of Health Sciences Computer Network System (NIHS-NET), which was named NIHS Information and Computing Infrastructure (NICI) previously. In the system, the main server machines and common machines were replaced and the network lines were upgraded from 100 Mbps to 1Gbps. The connection nodes were changed from Inter Ministry Network (IMnet) to Science Information Network (SINET), and the dedicated lines between NIHS (yoga, osaka, tsukuba) and SINET were constructed. The Internet connection speed from each campus to SINET was upgraded. We also performed security audit in this system.
