Contention Avoidance of Staging Communication and Inter-process Communication
Computer cluster systems execute staging in which data used by a job is delivered to computation nodes used by the job beforehand. The conflicts that causes delays in communication time of jobs are happened because staging is executed even when computation nodes used by other jobs communicate with each other. In this research, we resolve this conflict by using Software Defined Networking in order to reduce communication time of each job and to improve computation time of that.
Role-based network access control system
Frequent leaks of information assets at companies have been reported recently. In order to protect valuable information assets from security risks, security measures must be taken at each computers; however, a system to shut out unauthorized access in the network could add another level of security. Such system should be implemented in accordance with the organizational structure of a company (departments, security clearance levels, projects, etc.) and allow fine-grained and flexible access control. Based on this idea, our laboratory has been developing FlowSieve, a role-based network access control system built on top of OpenFlow. This research is a collaborative work with TIS Inc.
