Network Architecture Project
The Network Architecture Project is working on promoting overall strategies, including mobile-fixed convergence architecture, and realizing the overall IOWN architecture.
Specifically, we are striving to implement the overall IOWN architecture early by establishing a proof-of-concept environment for the All-Photonics Network (APN). We are conducting technical verifications for end-to-end optical path control and network resource design/control using this environment. Furthermore, we are working on end-to-end video distribution architecture tailored for services expected in the IOWN era, conducting both conceptual studies and proof-of-concept trials.
Promoting Overall Strategy for Core Research in Network Technology
With the commercial launch of IOWN services, R&D (incubation) and business commercialization (acceleration) are gaining momentum. As part of our network core research strategy, we are working toward the early commercialization of technologies, establishing future 6G/IOWN network technologies, and formulating business expansion strategies.
- Considering trends in network technology, market demands, and NTT Group’s business directions, we are formulating a cross-laboratory roadmap for core research and strategies for incorporating research outcomes into practical applications.
- In collaboration with business units and technology planning divisions, we are formulating a future ICT architecture that will meet AI computing demands in the distributed data center era.
R&D Toward the Realization of IOWN All-Photonics Network and Mobile-Fixed Converged Networks
We are researching and developing ways to expand the application areas of the IOWN APN, which provides high-capacity, low-latency, and low-power optical paths on an end-to-end basis.
- We aim to establish the Subchannel Circuit Exchange (SCX) technology, which will enhance the optical wavelength utilization mechanism of APN by subdividing optical wavelengths into virtual channels.
- We are researching network-integrated video processing technologies that can directly process video signals without conversion, enabling the low-latency distribution of high-definition video. This technology is being explored for applications in broadcasting and video production.

Additionally, we are advancing the Inclusive Core concept, which aims to seamlessly integrate mobile and fixed communications, computing and networking, and cyber and physical spaces.
- Leveraging ISAP technology, we are developing an architecture that seamlessly integrates networking and computing. We are conducting proof-of-concept trials in 5G environments, refining the technology through use cases such as network slicing, quality assurance, metaverse applications, and AI-driven optimization.
- We are developing a wallet service that will enable carriers to issue and securely manage Verifiable Credentials (VCs) for customer information. Additionally, we are exploring digital identity-based technologies to support priority control mechanisms in emergency communications.
