SINET6 adds 400G and resiliency to support research and education in Japan
The SINET academic information network, run by Japan’s National Institute of Informatics, supports research and education throughout the country and beyond. SINET6, which went live in April 2022, uses Juniper solutions to achieve four major goals: 400G connectivity, additional points of presence (POPs), and enhanced redundancy and security in the domestic network.
Upgraded the network infrastructure supporting Japanese research and education
Constructed 400G network with 70 connection points nationwide
Low-cost router redundancy at the point of connection
Strengthened measures against DDoS attacks
Expanding reach from universities to primary schools
With SINET6, the National Institute of Informatics has built a stable and high-performance 400 Gbps network nationwide with the MX series at its core. The number of connection points has been increased and an environment has been created that makes connections by universities and research institutions in each region even easier than before.
The ability to provide greater hardware redundancy for backup lines, something that was requested by many subscriber institutions with SINET5, is seen by Kurimoto as a major accomplishment. Redundant high-performance routers consume a lot of resources including electricity and installation space, and because of this, efficiency gains that are not visible were achieved. There are also higher expectations for reinforced DDoS countermeasures in preparation for the future.
The specifications of SINET6, which uses cutting-edge technology, are extremely advanced. During the initial investigations, Kurimoto and others thought it would be difficult to implement. It is certainly true that there were difficulties, but Mr. Kurimoto recalls, “We were able to fully realize the network environment through collaboration with various business partners,” including Juniper Networks, which assisted with the construction and operation of SINET5.
“Juniper Networks has been involved in this project since its beginning and we have been able to engage in very in-depth discussions. Juniper Networks contributed to investigating various technologies and methods as well as assessing the feasibility of SINET6. We were able to introduce state-of-the-art technology with the help of Juniper Networks and we are extremely satisfied,” said Kurimoto.
As mentioned in the opening, SINET6 is being considered for use by a wider range of research and education than previously and is expected to evolve even further as a network service. As subscriber institutions increase and their needs diversify, it will be necessary to increase the efficiency of and automate operations. Looking ahead, planning for the next generation of SINET has started.
