Science Information NETwork 4

The Science Information Network (SINET) is an information and communication network connecting universities and research institutions throughout Japan via nationwide connection points (nodes). It is designed to promote research and education as well as the circulation of scientific information among universities, research institutions, and similar entities. SINET is also connected to research networks such as Internet2 in the U.S. and GÉANT2 in Europe to facilitate dissemination of research information and collaborations over networks. SINET4 began operations in April 2011, and it replaces the previous SINET3. SINET4 plays an important role as the core component of the Cyber Science Infrastructure(CSI).

SINET4 positions all nodes in data centers, and is configured so that it has redundant backbones and high-speed reroute functions, producing greater network resistance against disaster and failures. It also features broadband connections to academic research networks worldwide. Consequently, SINET4 provides a stable, high-speed connection environment to approximately 700 universities and research institutions in Japan.

SINET4 inherits SINET3ʼs hybrid optical and IP architecture, achieving higher network speed, greater reliability, and more stable provision of services.Adopting dark fiber and WDM technology, the access lines are faster, for more flexible and economical performance.

SINET4 Architecture SINET4 Network Services

SINET4 was not damaged by Great East Japan Earthquake◆On March 11, 2011, a commercial power

black out affected SINET nodes in the Tohoku Region for an extended period (up to 96 hours), a result of the Great East Japan Earthquake. However, by refueling the emergency generators, the nodes remained functional, notwithstanding a gigantic earthquake with seismic intensity of 7 on the Japanese scale.

◆Regarding the links, almost all primarylinks were damaged, and for two of them, both the primary and the back-up were damaged. However, we were able to secure a bypass route and the backbone was able to secure a link with any given core node, keeping both the Sendai DC and Sapporo DC from being isolated.

◆IPv4/IPv6 packets were diverted by OSPFto other routes using surviving nodes and links and VPN packets were transferred without delay by MPLS protection/FRR.

SINET4 needs to provide the following variety of multilayer network services.

SINET4 Network Services

SINET provides L1/L2 on-demand services. When a user specifies an origin, a destination, duration, bandwidth, and route options on the Web, a path is automatically set up and becomes available for the user at the specified time.

Design for Layer 1/2 On-demand Services

(1)Equipment housing in data centers(2)Dispersed duplexed links for edge and core links(3)Redundant routes between core nodes(4)High-availability functions for each virtual service network

Design for High AvailabilitySINET4 adopts the following network design principles.

Facilitation of Private CloudUniversities can now establish a private network cloud environment on the SINET economically.・NII provides a framework that permits the

support of university research and education activities through the direct connection of cloud service providers to SINET4.

・As a general rule, each university shall connect its campus LAN to the facilities of service providers using L2VPN.
