AboutAbout the lab
Exploring how communication works through design and evaluation.
The Computer Network Lab studies the design of network protocols and the performance evaluation of communication systems.
In the faculty introductions of the College of Media Arts, Science and Technology, the lab is listed as a lab in the field of Internet Science.
Recently, the lab has been working on reducing power consumption of enterprise networks, flow distribution in SDN, detection of DoH traffic, and other topics.
Associate Professor Shigetomo Kimura is also listed as a cooperating faculty member in the College of Information Science.
Key terms

In the Internet Science field of the College of Media Arts, Science and Technology, researchers study technologies that improve the quality, performance, and security of the Internet itself, as well as technologies that provide energy-efficient and seamless communication. This lab works on power saving, flow distribution in SDN, detection of DoH traffic, and delivery routes for drone logistics.
*Illustrative imagePower Saving in Networks
To reduce the power consumption of enterprise networks, the lab studies methods that switch the communication speed between SDN switches. It also covers methods for switching bandwidth between switches based on a traffic-splitting approach.
*Illustrative imageFlow Distribution in SDN
The lab studies algorithms that use segment routing to distribute traffic flows in SDN. It also covers methods for reassigning switches between controllers in SDN with multiple controllers.
*Illustrative imageDetection of Encrypted DNS Traffic
The lab studies methods in which a middlebox, a device placed along the communication path, detects DoH traffic by using information that is not encrypted.
*Illustrative imageDelivery Routes for Drone Logistics
In drone logistics networks, the lab studies how to divide the logistics area and determine delivery routes that reduce the computational load on the drones.
