Specific Research Topics

CCI (AI Platform) and Deep Learning Optimization TechnologyThe key factor in the business environment of enterprises is whether they can pursue digital transformation using AI, particularly deep learning. We are engaged in R&D aimed at dramatically accelerating the introduction of deep learning into business activities.

Secret Sharing and Secure ComputationSecure computation is a technology that allows carrying out analyses of encrypted data. The data is first dispersed, using secret sharing, into fragments called “shares” which are distributed on separate servers, and one can then perform data analysis without reconstructing the original data. This makes it possible to process data to be in a safe and secure manner: for example, statistical analysis of confidential medical data can be conducted while fully preserving security and privacy. By developing novel algorithms achieving world-record breaking performance, we have already enabled commercial-grade applications of secure computation that were previously considered out of reach, and we are now directing our R&D efforts towards applying it to even larger-scale and more complex targets.

Anti-Malware TechnologyThis technology is designed to facilitate detection, collection, and analysis of malware, such as computer viruses, and countermeasures against it. The technology uses honeypot trap to detect and collect malware samples and attacks targeting a variety of vulnerabilities, analyzes their functions using both dynamic and static analysis, and uses the analysis results to develop countermeasures. In order to be able to respond to ever-evolving attacks quickly, we are working on unknown attack detection technology, malware analysis technology that makes use of virtualization, and many more.

Service co-creation network based on NetroSphere ConceptNetroSphere Concept aims at quick, reliable and low-cost provision of a variety of services that users, such as service providers and other customers, will need when our future networks are introduced. Based on this concept, we are developing architecture that enables the user to access security and other network functions flexibly. We are also developing network technology that will enable a range of devices, from terminals to servers, to be used safely and securely from end to end in order to support the creation of a variety of services in the age of IoT.

One-stop operation that contributes to the creation of new services and industriesWith a view to providing operations that encompass networks, clouds and applications, we furnish service providers with operation services that enable them to maintain and operate networks and services in an integrated manner, and network providers with a one-stop operation function that makes more efficient use and operation of resources possible. In addition, we are working on social platform operations that provide, through a common API, advanced functions based on security and Big data technologies. The objective is to promote the creation of B2B2X services and eventually enable individuals to create services easily.

Access network technology and infrastructure technology that contribute to creation and expansion of new servicesWe are aiming to provide a flexible access network that will make connecting to networks easy, simple and secure to use, and can support a wide range of service demands. For this purpose, we are adopting a multi-faceted approach to R&D, including advanced systems that allow services to be accessed via optical fibers and wireless access, optical fibers with a new structure that allow transmission of a large volume of data, technologies for maintaining and managing communication infrastructure equipment, and a network control system that allows efficient operation of access networks.

Electromagnetic environment design technology and Environmental impact assessment technology To protect the global environment and ensure high network reliability, it is important to reduce the impact of future networks on both climatic and electromagnetic environment. To reduce the environmental loads and electromagnetic disturbance generated by ICT device that will comprise future networks, we are formulating requirements that will govern their design and development process. We are also studying how to assess the environmental impact caused by changes in society and our lifestyle that will result from the widespread use of future networks.

Infrastructure Technology

MSF (Multi-Service Fabric)This network technology makes the most of commodity components by separating conventional proprietary equipment into software needed for each service and hardware common to all services and have them handled by the controller. By flexibly combining various component resources, including white box switches, it can provide adaptable services in a timely manner. It can also save space and reduce power consumption. We aim at global deployment of the technology by encouraging open development (OSS development ) of the MSF controller and the network OS (Beluganos).

Zero-Touch Operations Technology24 / 7 operations prepared for failures are needed to maintain network services, which have become important social infrastructures. Conventionally, operators have made decisions and carried out control based on their experience and skill. Zero-touch operations aim at rapid and skill-free operation by automating service recovery from failures by providing autonomous network control capability.

To establish core technologies for 5G services, we are developing the following technologies:

● Use of PON technology to simplify distribution cabling in wireline sections and to allocate bandwidth efficiently to APs

● Use of low-latency optical access technology to connect optical line terminals to the base station efficiently with low latency

● Use of next-generation high-density coordinated wireless LAN technology to suppress radio interference in high-density environments and to carry high-capacity wireless traffic

QoE-Centric Operation As network services become increasingly diverse and virtualization is introduced into networks that support these services, it has become difficult to determine the impact of a network failure on the quality of service perceived by end users. This technology enables the network operator to evaluate the quality of experience (QoE) perceived by the end user from information collected from both inside and outside the network , and monitors the network and controls it accordingly. In addition, it enables the network provider to share QoE information with service providers and end users so that the latter can optimize the services accordingly. This makes it possible to achieve high user satisfaction for the services.

Super-High-Density Space-Division MultiplexingOptical Communication TechnologyWe are developing core technologies for a next-generation optical communication system using multi-core, multi-mode optical fibers in order to realize a scalable optical network that allows high-capacity transmission with a transmission rate on a single optical fiber that exceeds the current rate by a factor of 100 to 1,000. By combining a multi-core fiber having 12 cores and a multi-mode fiber, in which 3 signals are multiplexed in 3 different modes on a single wavelength, we conducted the world’s first successful experiment of super-high-density space-division-multiplexing transmission with the number of space multiplexed signals exceeding 30 (36 space multiplexed signals: 3-mode multiplexing times 12-core multiplexing).

Edge ComputingWe are working on edge computing technology, which allows edges close to objects, clouds and terminals to share and coordinate processing in order to achieve low latency in application processing and optimize communication traffic flow. In particular, we are studying how to divide and geographically allocate the logic parts of applications. By applying edge computing to the control of devices that require a rapid response and the processing of a huge amount of diverse data, we are helping to “drive the real society” in the IoT age.

Phase-Sensitive Amplification Technologyto Make Ultimate Low-Noise Optical Amplifier a RealityTo further increase the transmission capacity of optical communication, we are developing a phase-sensitive amplifier (PSA*1) that realizes ultra-low noise amplification without signal degradation, thus overcoming the theoretical limitations in systems that are based on conventional optical amplifiers. Moreover, the PSA can retrieve degraded optical signals after optical fiber transmission over long distances. Using the world's highest efficiency PPLN*2 in the optical amplification section, which is the key part, we have achieved low-noise amplification below the standard quantum limitation (NF=3dB) of conventional amplifiers.
