By leveraging Juniper Networks' MX series routers, Japan's National Institute of Informatics (NII) has been able to construct a full-mesh network, connecting over 50 data centres inside and outside of the country.
SINET is an academic research network utilised by approximately 850 universities and research institutes in Japan, with connection hubs nationwide. The network also delivers connectivity in conjunction with research networks in the U.S., the EU, and Asia to drive domestic and international research projects through SINET.
To keep up with research networks in Europe and America, where 100 Gbps connectivity is widespread, NII needed to upgrade its network to SINET5 to realise shorter transmission delays and handle higher traffic volumes efficiently.
Moreover, the previous network SINET4, had a tree topology, where core nodes (routers) were installed in eight major cities throughout Japan, with branches-to-edge nodes (switches) in each region. As data traffic increased over the years, the network was plagued with transmission delays and required high management workload due to the overall number of switches.
To counter these problems, NII utilised Juniper Networks MX Series 3D universal edge routers in SINET5 to provide 100 Gbps full-mesh connection across its 50 data centers, and minimise delays by eliminating hops.
The new network can also support a variety of interfaces, from 1 Gbps to 100 Gbps, to accommodate a diverse range of subscribers.
Besides that, the Logical Systems feature built into the MX Series enabled multiple virtual routers for various types of VPN to be configured within a single physical router. It also allows virtual routers, bridges, and switches to be created within the router to deliver various types of access and services, according to Juniper Networks.
The new network also enables NII to scale as needed as it can be easily upgraded and scaled-up using 400GbE-ready line cards. "[Juniper Networks' solutions] enable SINET to grow flexibly, so that we may continue to construct the academic information infrastructure that will drive cutting-edge research and education in Japan," said Professor Hiroshi Yamada, Research and Development Center for Academic Networks at NII.
