Abstract
Recently, technology of cloud computing has been rapidly developed, and it is expected to apply for various network services. Virtual technology is a part of significant technology which has been contributed for the development of cloud computing. Various virtual technologies such as virtual OS and VDE become very important for server and network management in these days. Furthermore, such a virtual technology becomes possible to provide efficient resource management or QoS with virtual network configuration. Thus, it will be important for network construction to provide hardware and software service in near future. Autonomous network configuration in virtual layer is one of such a service. Not only network configuration is constructed in physical layer, but also it should be constructed in virtual layer for providing optimal resource and QoS management. In this paper, Overlay Cloud Computing Service is proposed, and it is consisted of virtual autonomous network configuration in cloud computing service including various server and network services. In our proposal methods, first of all, there are various kinds of user policy such as eco mode, high power mode, and secure mode. Then, virtual network and server configuration is automatically held in virtual layer with the mode setting and hardware configuration. Besides, with observation values of network and server condition, virtual configuration is changed optimally. In this optimal configuration changes, Kalman filter is used for the calculation of network and server condition. Then, with the results of calculation, virtual network topology is changed. In this paper, first, introduction and cloud computing service is discussed. Then, our proposed Overlay Cloud Computing Service by autonomous network configuration is introduced. In the chapter, optimal control method by Kalman filter with observed values is also introduced. Finally, conclusion and future study is discussed.
