Laboratory Introduction

Make the future more excitingmake your inspiration real

Internet Architecture and Systems Laboratory (also called "inet-lab") was founded in April 2011 under the leadership of Professor Kazutoshi Fujikawa. "Make the future more exciting" and "make your inspiration real" are the policies of our laboratory.We research mainly Internetworking, Ubiquitous Computing, Network Security and Network Traffic.

    We research ways to implement more secure and convenient communication architectures that everyone can use.We also consider the next-generation ICT infrastructure technologies and services, and we research what is necessary for it.
    In order not to end the research just on simulation, we verify it and make it useful by using the systems and equipment operated in the Integrated Information Infrastructure Center (ITC).

Research landscape

Research meeting

We create several groups for each research field and hold progress meetings in each group once a month. In the meeting, we report on their own research situation and check progress on various research tasks (in-campus presentations, academic societies, dissertation submissions etc...).

Also, those who are particularly close in research fields conduct a more technical research meeting once a week. In addition, ad hoc meetings between teachers and students in a corner of the student's office are also frequent.

Technical Books Reading/Conference Paper Reading Lecture

There are some lectures necessary and voluntary. The necessary lectures is for new students.

The voluntary lectures vary yearly, but in recent years they have held a Lecture on parallel processing programming, a reading Linux kernel code, and Machine Learning/Deep Learning algorithm. Every lecture will be conducted approximately once or twice a week.

TCP/IP Lecture

It is a lecture to learn the basics of TCP/IP networking. We read several titles related to TCP/IP and each one will make an presentation of about one hour. In recent years I am using A·S·Tanenbaum's book.

Server/Network System Construction Lecture

In order to acquire practical skills related to networking, each person constructs a PC router using real machines, and creates an experimental network in the laboratory to operate. Starting with the creation of Ethernet cable, installation of OS, we aim to eventually enable some kind of dynamic routing. Since you basically perform remote login and operation, you can become familiar with console control and various Unix commands. After completion of the lecture, you can also use the created router as various servers or for experiments.
