NTT Group’s R&D

R&D that Advances Growth Strategies

NTT Group is moving ahead with initiatives to follow a track of growth in profits under the Medium-Term Management Strategy, “Towards the Next Stage 2.0.” The Group is implementing R&D activities in accordance with this strategy.

We are working to create competitive technologies, which are the source of growth for the Group, and to implement development activities that support increases in cost efficiency, such as network simplification. Furthermore, we are striving to develop technologies to advance the creation of new value through collaboration with other companies and to implement leading-edge research with a focus on the future. Moreover, we will use the new technologies that result from these R&D initiatives to address a number of objectives. These include working to achieve sustained gains in corporate value through the resolution of social issues, such as the aging of the population; to strengthen industrial competitiveness, which is an objective of the national government; and to contribute to the development of society through the vitalization of local economies.

Creating Competitive Technologies That Will be Sources of Growth for NTT Group

Security Orchestration

Strategically, security is an extremely important development theme for maintaining a competitive edge in global cloud services and for building a solid platform for the generation of new businesses through the B2B2X model.

Cyber-attacks continue to grow more skilled and sophisticated each year. In particular, there is a need for rapid, effective security measures for networks, which can influence the entire social infrastructure. Accordingly, NTT Group is advancing the development of security orchestration technologies. For example, reflection DDoS attacks cause network congestion with huge amounts of traffic, but our security orchestration technologies can shut off these attacks at the optimal point, without hindering normal traffic. In addition, networks can be restored in an autonomous manner through automatic control. NTT Group will examine the introduction of these technologies on entire networks.

AI and IoT Targeted by NTT Group

NTT Group does not aim for AI that emulates human intelligence or thinking but rather for AI that substitutes for and supports certain activities and that coexists and co-creates with people, thereby fostering the realization of abundant lifestyles.


We have defined four types of AI technologies that we will work with: Agent-AI, Heart-Touching-AI, Ambient-AI, and Network-AI, and we have chosen corevo™ as the brand name for the Group’s AI technologies. We are already advancing a variety of initiatives that utilize our AI through collaboration with diverse partners, and these initiatives incorporate the concept of fostering a revolution in technology.

NTT Group is aiming for sentient IoT, which integrates locality, which is one of the characteristics of IoT, with the concept of Ambient-AI (analysis of humans, objects, and environments; instant forecasting and management). Based on this approach, NTT Group has developed and is providing R-env: Rembu®, a general-use, shared interface that facilitates free combinations of robots and a wide range of other IoT devices, Big Data processing technologies, visual and voice recognition techn­ologies, and other technologies. New services utilizing these technologies are already being created in such fields as finance, transportation, nursing care, lifestyles, and business.

Four Types of AI in NTT's R&D

Increasing Network Cost Efficiency

Achieving Both Cost Reductions and Flexible, Rapid Service Provision

To date, it has been difficult to advance the utilization of general-use products on carrier networks, where high reliability and high scalability are required. Accordingly, there have been limits on operational flexibility and on thorough cost reduction initiatives.

NTT Group has formulated the NetroSphere concept, which makes it possible to divide network functions into small modular components and freely assemble those components to create diverse services. Targeting the realization of this concept, we are implementing R&D initiatives utilizing virtualization technologies with next-generation carrier networks. Through the use of virtualization technologies, such as NFV*1 and SDN*2, and inexpensive, general-use products, we are working to develop technologies that realize highly reliable network services utilizing inexpensive, general-use products and also provide necessary services in a flexible, rapid manner. These technologies will facilitate efficient network operation, and reductions in capital investment and operating expenses can be anticipated.
