On 1999, JGN started operation of domestic optical fiber network. From 2004, As JGN2, We added domestic and international access point, increased network bandwidth, stared IPv6 routing and installed optical switches. Moreover, From 2008, As JGN2plus, ''Service Platform Architecture Research Center''(SPARC) is operating testbed network which is providing various services for research and development of next generation network.
JGN2plus is a testbed network to support the New Generation Network (NwGN) promoted by NICT. The network supports the R&D activities at the JGN2plus research centers (SPARC) and, like the previous testbed networks as JGN/JGN2, it enables researchers to conduct demonstrative experiments for network R&D and various applications. JGN2plus is open to researchers for R&D purpose.
JGN has been supporting cyberinfrastructure as well as advanced networking instastructure for wide variety of applications such as …
- Broadcasting service (IPv6, various type of multicasting, HD, 4K image)
- Optical networking (optical switch, GMPLS, G-lambda)
- Other applications (remote lecture/telemedicine etc.)
- Next generation TCP
- To design new testbed for NwGN :
- those variety of activities to be taken into account.
- testbed network be built on existing and operational technology
- testbed network supports evolution of technology
- Testbed is used for
- proof of concept
- international collaboration and standardizatio
- social implication
- human resource development
