This research is part of a strategic program focused on social implementation and overseas expansion for the Innovative ICT Fund Projects for Beyond 5G/6G. The goal of this research is to develop technology that allows users to utilize multiple cloud data centers simultaneously and switch connection destinations flexibly.
This technology will also ensure fault tolerance and service quality through cooperation with the All-Photonics Networks (APN) of multiple providers. Additionally, a small APN node will be developed to enable APN deployment at rural data centers and small- to medium-sized sites.

APNs: Meeting Capacity and Processing Demands
In the era beyond 5G/6G, there will be a need for increased information processing and transmission capacity. APNs are becoming more important to meet these demands and provide lower power consumption for carbon neutrality.
Discussions on providing APNs widely to society have been ongoing, leading to the need for technology that can connect multiple sites simultaneously and collaborate among providers. To address these needs, NICT solicited proposals for the Beyond 5G/6G Fund Project, to which NTT, KDDI, Fujitsu, NEC, and Rakuten Mobile submitted joint proposals. These companies were selected to implement the program and will focus on developing APNs that can cooperate among providers, ensure fault tolerance, and enable flexible connection switching.
The research and development (R&D) will focus on developing the overall APN architecture and common APN infrastructure technology. This includes photonic network federation technology, subchannel circuit exchange technology, and distributed ROADM technology. These technologies will enable the seamless use of APNs from various providers, allowing for high-speed, low-latency connections to multiple services and the flexible switching of connection destinations.
Overall, the goal of this collaboration is to create a society where APNs from different providers can be used seamlessly, enabling high-speed connections and flexible switching between services. The five companies will work together to achieve this vision.
