We research next generation Cloud infra-software, Stella Project, which includes the two core development technologies for multiple SLA guarantee of multiple users. First core development is to integrate the scheduling of the CPU, network, and storage resources. Second is Cloud-wide SLA guarantees including resource admission control, job allocation, and management techniques.
Software-defined network (SDN) is a new paradigm of Internet architecture. SDN has several benefits; easy network management, evolution without dependency between planes and low cost to expend. Our research group try to solve issues in terms of network virtualization in SDN including following keywords.
In general, the real-time task scheduling does not work in a virtual machine-based system because the physical resource scheduling and management is done at the lower layer, namely, the virtualization layer. And recent system virtualization approaches are focusing on performance issues; however, Real-time(RT) systems are affected by the underlying hardware and its configuration. Depends on the configuration, system parameters such as execution time of tasks, execution period, system utilization, etc are affected. RT system schedulers have a unique scheduling policy that all the real-time tasks can finish their jobs within a given deadline always. But, the virtualization layer is focusing on the performance issues. Therefore, previous Virtualization techniques is not able to achive real-time process. Our research interests are as follow.
