In this paper, we develop a system to support learning of OpenFlow by visually associating controller configuration information and logical topology. In our system, the constructed topology is visually shown on a touchscreen display and a learner can easily confirm the topology. In addition, a learner can configure the controller by visual and simple operation using the touchscreen display. Therefore,...
One of the promising sensor network application is for the primary industry and we have proposed a fish farm monitoring system. In our system, sensor data monitored at a fish-mounted sensor node is transmitted to a sink node by using acoustic communication. Since we assume that a sensor node is attached at an abdominal cavity region of fish, the transmission range of acoustic wave is not omni-directional...
In network education, there are several benefits for conducting cooperative practice among a variety of learning levels of learners. We have proposed a hands-on IP network practice system by constructing a virtual network on a cloud server. In our past study, we introduced a pseudo cooperative practice function to our system so that cooperative practice with a companion agent can be accomplished even...
We have developed a screen sharing system to share contents between two persons, and applicable to one-to-one remote teaching. The screen of a PC at one side is shared with the screen of a tablet at the other side through the network to convey instructions from an operator to a collaborator. This system makes it possible to arbitrarily select a part of the screen of the PC at the operator side. The...
OpenFlow network technologies has attracted attention along with popularization of cloud environment and server virtualization since it enables flexible network configuration. It is expected that existing networks of many organizations will migrate to OpenFlow networks in the future. Since it takes a huge cost to replace all existing network devices to OpenFlow switches, many organizations consider...
Studying networking technologies has become one of the most important subjects in the field of Technology of junior high schools and Information Study of senior high schools in Japan. To study these subjects, studying with practically andexperimentally is strongly recommended by MEXT (Ministry ofEducation, Culture, Sports, Science and Technologies in Japan). However, there is little equipment for...
Education of network security has attracted a lot of attentions due to increasing unauthorized access, lack of engineers who have network security skills, and so on. Although practice using actual computer networks is highly important for network security education, it requires costs to prepare a computer network for practice. We have proposed a network security learning system by constructing a virtual...
Drumming motion of percussion is important to play music, and it can learn efficiently by coaching from expert. However, if novice drummer cannot get coaching from expert, they practice percussion by oneself with use of book. Then, it is difficult for novice drummer to measure of practice result. We have been developing self learning system for novice drummer. Using this system, novice drummer can...
In this study, we developed an automatic network replication system for Open Flow network. This system can automatically and virtually replicate Open Flow network according to captured information. This system consists of mainly two functions: Message Capture Function (MCF), Network Emulation Function (NEF). MCF is located between Open Flow controller and Open Flow switch. MCF can capture message...

The purpose of this study is to give students hands-on practical learning for IP network skills. We have been developing the hands-on IP network practice system using virtual machines. Students can practice IP network skills freely at anytime on just one general-purpose PC. We have implemented this system by applying the virtual Linux environment User Mode Linux. In this research, we developed two...
The purpose of this study is to give students a hands-on practical learning for IP network skills in campus cloud computing. It is important for students to operate network devices repeatedly to learn network skills. However, in practical learning with real network devices, students need a number of network devices. For this reason, it is not easy for students to prepare environment to be able to...

An integrated field monitoring system has been studied for sustainable and high quality production of agricultural products by applying some kinds of sensing and information techniques to acquiring and analyzing growth information of crops in cultivation process. This study is conducted under the BIX (the abbreviation of bioinformation exchange) concept. This is the XML standard for the data exchange...
