A Three-Phases Scheduling in a Hierarchical Cloud Computing Network

Network bandwidth and hardware technology are developing rapidly, resulting in the vigorous development of the Internet. A new concept, cloud computing, uses low-power hosts to achieve high usability. The cloud computing refers to a class of systems and applications that employ distributed resources to perform a function in a decentralized manner. Cloud computing is to utilize the computing resources (service nodes) on the network to facilitate the execution of complicated tasks that require large-scale computation. Thus, the selecting nodes for executing a task in the cloud computing must be considered. However, in this study, a three-phases scheduling in a hierarchical cloud computing network is advanced. The proposed scheduling can utilize better executing efficiency and maintain the load balancing of system.
