My current major work is development of virtualization nodes (routers).
This is part of a research project on "New Generation Networks"
conducted by NICT.
I am also interested in
developing a new voice-communication medium called
voiscape, which can be more widely used than telephone or conference systems.
My work until fiscal year of 2001 was on active networks
(computing networks), policy-based networking, and
internet QoS (quality of service). Until around March 1999, I have been
studying and developing methods for searching and reorganizing
information placed on the Internet, e.g., WWW or online encyclopaedia,
especially on
"thematic search" / "axis-specified search".
I believe my lifework that connects most of the above researches is "fusion of analog
and digital", or "fusion of symbols and subsymbols".
These research-related information can be accessed through
"research themes overview" or
"research topics".
My paper list is in "paper summary".
Recently, I started a blog.
This blog contains information not limited to my research, but it contains much less
information than the Japanese version.
In addition, I supply East Japan Earthquake Support Information Blog (in Japanese), the Great
Hanshin Earthquake Page (in Japanese), and
the Great Hanshin (Kobe) Earthquake Page (in English, but most links are dead).
My Current and Past Research-themes (reverse order)
- Network virtualization
- Development of network virtualization platform, which consists of programmable network nodes and which enables creation of virtual networks that is not restricted by conventional protocols such as IP or Ethernet.
New generation networks are studied on this platform.
- voiscape: a virtual "sound room" based communication medium
- Development of a new communication medium by which two or more persons can talk each other by
using a virtual sound space based on spatial sound technology.
- Active Networks, Policy-based Networking, and QoS Guarantee
- Research on development of programmable and virtualized network, and methods of combining (composing) policies, or on component-based policies.
- Axis-Specified Search (Thematic Search)
- Development of search methods in which users (searchers) specify an axis of search in addition to keywords and in which the search results are arranged along the axis.
- Self-reproduction of Web pages
- Small-scale research on developing a method for reproducing and displaying exactly or almost the same Web page as the original.
- CCM: Chemical-Computation Model
- Research on a computation method in which only local information is used, i.e., each action in CCM refers only a few data, and there is no global plan (i..e., no program) for the computation.
- RACA: Randomized Asynchronous Cellular Automata
- Small-scale research on asynchronous and non-deterministic (i.e., randomized) cellular automata, but an article in Wikipedia described it (in March 2007).
- Logic/Symbolic Vector Processing
- Development of methods of vector processing
of logic programming languages and/or symbolic vector processing etc.
- Programming Linguistics
- Research on programming languages (programs) using the methods of linguistics.
- Programming Language Processing for Vector / Parallel Computers
- Development of a programming language and compilation techniques for a MIMD computer and vector (SIMD) supercomputers.
- Programming Language Processing for Scalar Computers
- Development of compilers of programming languages, SIMPL and Pascal.
