Next generation cloud infra-software toward the guarantee of performance and security SLA
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.
Developing Next-generation Cloud system guarantee user requirements for performance and security SW
Develop CPU, network, and system guarantee the user requirements for the storage performance SW
Develop Cloud security system (availability, integrity and confidentiality) guarantee user requirements for SW
Develop SW of Cloud platforms with integrated 1 and 2 systems
Create SW system-specific open source community through the public Cloud test bed
Establish testbed of Cloud Distributed System SW
Establish and operate Community based on open source test bed
Perform education that aims Community such as Cloud / Security / system SW
Carrier grade SDN controller and network virtualization platform
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.
Controller that supports SDN 2.0 including Network hypervisor, Extended South bound Interface(xSBI) and traffic engineering(TE)
Network hypervisor providing Network slicing, global topology management and network fault detection and recovery
Extended SBI to support various network devices such as OpenFlow, MPLS, and LISP etc.
Traffic Engineering to monitor global network and traffic status.
System software such as operating systems, hypervisors, software defined networking (SDN) platform and cloud platform should be secure, fault-tolerant, and robust. We currently try to solve various security issues using system-level insights and expertized knowledge such as OS structure and system behavior analysis. Our research interests are as follow.
Secure and robust system software issues for modern computing platforms: cloud server, cloud terminal, SDN applications/system, and Internet-of-Things devices.
Autonomic, evolvable and generic methodologies for handling unidentified threats targeting modern computing platforms
And, all other system-level security issues
Security research group in OS Lab currently studies following target systems.
System S/W structures, management policies, and mechanisms for automatically detecting unidentified threats in cloud computing
General-purpose system for the device authentication by dynamic and adaptive policy selection considering limitations of Internet of things device
Network operating system (NOS) and hypervisor for securely managing forwarding information base (FIB) and network applications
