As Figure 1 is showing, Kyushu University is connected with Science In-formation Network 5 (SINET 5) which is deployed by the National Institute of Information. Kyushu University Hospital is one of the divisions of Kyushu University and it’s connected with SINET, too.

The network services specialized for the research or for the education is called as the Research and Education Network (REN). With depending on its covering space, the names of the National REN (NREN) and the Regional REN (RREN) exist, too.

SINET has some satellite exchange points in USA. At those points, some NRENs or RRENs are interconnected. If those NRENs or RRENs allow the traffic transit, SINET can have the communication with the remote NRENs or RRENs which don’t connect with SINET directly. ANKBUT, which is the NREN of the United Arab Emirates, and RedCLARA, which is the RREN in the Latin America are such RENs.

Though the Mexican NREN CUDI and the Brazilian NREN RNP are the members of the RedCLARA, SINET connects with them through the USA west coast covered NREN Pacific Wave or the Internet2, which covers the universities, the educational institutions, and the none profit research institutions, provide the transit service to them.

GÉANT is the RREN which covers the whole Europe, and the centreal Asian RREN CAREN, the RREN ASREN which covers the northern Africa and the Arabian peninsula, and the South Africa NREN TENET are available through the GÉANT. The AfricaConnect is the on-going project, and when it’s ready, the RREN UbuntuNet Alliance which covers the central and south Africa will be available.

Asi@Connect is providing the interconnectivity inside, the east, the south east and the south Asian area. This project is the successor of the Trans-Eurasia Information Network (TEIN 4) in 2016. This RREN is planning to expand the connectivity to Myanmar, Mongol Uls and Afganistan.
