Computer Network Lab
Machine-translated · View original
The lab designs and evaluates the communication rules (protocols) and performance of computer networks.
AboutAbout the lab
Exploring communication protocols and their performance.
The Computer Network Lab studies the design of network protocols and the performance evaluation of communication systems.
The graduate school's research introduction lists process algebra, network protocols, and efficiency evaluation of communication systems among the lab's research topics.
In recent years, the lab has published research on energy-saving networks, SDN, and delivery routes for drone logistics.
In the Internet Science field of the College of Media Arts, Science and Technology, to which the lab belongs, research examples include technologies that improve network quality, performance, and security, and technologies that provide energy-efficient, seamless communication.
Key terms
- Network protocol
- A set of agreed rules that defines the procedure by which computers communicate with each other
- Process algebra
- A mathematical tool for describing the interactions between concurrently running processes as expressions and analyzing them
- SDN
- A mechanism that controls network devices, such as their routing, through software
- DoH
- A mechanism that encrypts DNS name-resolution queries and sends them over HTTPS

The lab studies how communication works from two sides: the design of network protocols and the performance evaluation of communication systems. Recent publications cover energy saving, SDN, detection of DoH traffic, delivery routes for drone logistics, and more.
*Illustrative imageEnergy Saving in Networks
To reduce power consumption in networks within organizations, the lab studies methods that switch the communication speed between switches according to conditions. It also investigates methods that split traffic for handling.
*Illustrative imageTraffic Control in SDN
In SDN, which controls networks through software, the lab studies methods that use segment routing to distribute traffic flows, as well as methods for migrating switches among multiple controllers.
*Illustrative imageDetecting DoH Traffic
The lab studies methods for detecting DoH traffic at middleboxes (devices along the network path) by using information that is not encrypted.
*Illustrative imageDelivery Routes for Drone Logistics
In drone logistics networks where the delivery area is divided into sections, the lab studies ways to determine delivery routes that reduce the computational load on drones.
