Overview

We research fundamental aspects and advanced application of network technology, while simultaneously implementing and managing a university network connecting several research facilities and six campuses.

Designing the Next Stage Networking Infrastructure

In 1986, the Internet in Japan was started as an experimental network connecting three universities – University of Tokyo – Information Technology Center (previously known as the University of Tokyo Computer Centre), Keio University, and the Tokyo Institute of Technology. Since then, the Internet has grown into a huge network of people and things (devices), which present-day people cannot imagine their lives without. We continue to advance our research into the next generation of network infrastructure, studying a range of fundamental and advanced topics.

It is also our role to design and implement the intra-university network system, called “UTnet”. Six campuses starting from Hongo, Komaba, and Kashiwa to several research facilities widely distributed across the nation, accompanied by frequent organization changes from time to time.

Each of the university departments have different networking requirements, so we should fulfill the requirements flexibly.

Research Subjects

Improving communication quality of wireless networks and creating applications

In a wireless network, a variety of factors in the facility environment affect the quality of transmission. The Network Research Division is pursuing research from basic technology to applications in this field. One area of research is improving transmission efficiency and quality when there are many simultaneous users and radio relays. Also, the division is engaged in a project to provide optimal routes to cars in transit, allowing them to avoid traffic jams and reduce travel time.

New Network Technologies for Widely Distributed Environment

We have been developing new network technologies using mobile small devices such as weather sensors and acceleration sensors for constructing a safe and secure society.

Utilizing the cloud with microcomputers

Using low-energy and highly mobile microcomputers, the Network Research Division is researching methods for transmitting information to the computing cloud and effectively gathering and presenting information stored in the cloud.

User interface using augmented reality technology

The Network Research Division is researching methods to realize user experience with high reality by using simple equipment based on cross-modality, which leads to perceptual illusions.

Development and deployment of fundamental technologies for wide-area distributed clouds

This area of research focuses on fundamental technologies for inter-clouds, which make highly resilient and efficient distribution of resources possible. The Network Research Division is creating actual wide-area distributed clouds that connect universities and is conducting field trials.

Analysis of Cyber Security

We are researching methods to predict and prepare against cyber attacks, using comprehensive analysis from DNS (a system convert both host names to IP addresses and IP addresses to host names) information, network traffic behaviors, and information provided from external databases. This is a joint project with Japanese and European universities and corporations.
