Hello
こんにちは

My research and teaching areas are communication network architectures, protocols, and algorithms. I design network protocols, model them, and evaluate their performance after having them implemented in experimental systems.

Research overview:

Communication networks have become essential to our daily life. We have been using communication networks for a verity of services such as telecommunication, information access, entertainment, shopping, banking, and education.

The Internet is the most widely used communication network. It has become a converged network for proving all the traditional communication services – fixed and mobile telephone, radio, and television services – as well as the new online services. The original Internet architecture designed and developed about 40 years ago was rather simple as its intended was to provide best-effort packet delivery from one computer to another without maintaining any communication states inside the network. However, the current Internet has become rather complex because of a lot of new functions added recently to the original architecture to enable it to support a variety of emerging services and their requirements such as security, quality of service (QoS), mobility, and reliability. Consequently, the Internet architecture has become suboptimal.

Therefore, in order to develop a sustainable network to serve the future society, we have to research and develop new networking technologies and architectures. For this purpose, the future Internet related research activities are being pursued worldwide. In Japan, the future Internet research activities are being carried out under New Generation Network research projects. I have been actively involved in R&D of the New Generation Network since 2006.

Topics of study:

In my class, we study the Internet architecture, its basic protocols, their limitations, and recently developed new protocols to overcome these limitations, although partially. We then study new networking technologies being considered for the future Internet or new generation networks. Among these technologies, we study ID/locator split based protocols to make the future Internet natively support mobility, multihoming, security, scalable routing, and heterogeneous network layer protocols. We study information-centric or content-centric networking (ICN/CCN) technologies for addressing, caching and delivery of contents more efficiently. We also study delay or disruption tolerant networking (DTN) protocols for enabling communications over networks with unreliable and long-delay links. We also study technologies for switching optical packets for achieving greater bandwidths and energy efficiency. We study activities of standards development organizations (SDOs) on the network architectures and protocols.

NOTE:Most part of my lectures would be delivered in English. The presentation slides as well as reference material would be in English.

Profile:

I received a B.E. in Electronics and Electrical Communications from Punjab Engineering College (now PEC University of Technology), Chandigarh, India in 1995, an M.S. in Computer Science and Engineering from Seoul National University, South Korea in 2003, and a Ph.D. in Informatics from the Graduate University for Advanced Studies, Japan in 2006. After the B.E., I worked as a computer engineer and part-time lecturer for about four years. After the Ph.D., I joined the National Institute of Information and Communications Technology (NICT) located in Tokyo as an Expert Researcher (Postdoctoral position). I became a permanent researcher in 2010 April and then a senior researcher in October. At NICT, I have been involved in the design, implementation, evaluation, and optimization of algorithms, protocols, and architectures of New Generation Network or the future Internet. In particular, my current research interests include new naming and addressing schemes, ID/locator split protocols, integration of heterogeneous network layer protocols, integration of resource-constrained sensor networks into the Internet for ubiquitous sensing and computing, content-centric or information-centric networking, distributed mobility management, and privacy, security and trust in communication networks. I have published several dozens of research papers in journals, magazines and international conferences. I have also edited four ITU-T Recommendations for the standardization of Next Generation Network (NGN) and future networks. I have received the ITU Association of Japan Award in 2009 for my active contributions to the ITU-T Recommendations. I have also received the Best Paper Award (second prize) at the ITU-T Kaleidoscope event on Innovations for Digital Inclusion, held in Argentina in 2009.
