碩士 === 國立臺灣科技大學 === 電機工程系 === 101 === With the rapid development of the Internet, cloud computing has emerged as an important issue cause of change to typical network services. Unlike conventional point-to-point connection services, cloud services will enable the goal of user-led diversified services to be achieved. Nowadays, cloud computing has provided users with diverse and highly flexible application services. In this work, various clouds are connected to each other to develop an Inter-Cloud system that offers users more diverse range of services. This work proposes a load-balancing mechanism in an Inter-Cloud computing system to implement the service-related decision policies by analyzing the resource of cloud and utilization of OpenFlow-based SDN switches to optimal processing performance. The concept of the SDN (Software Defined Network) is used to optimize the distribution of network traffic in dynamic Inter Cloud system. This mechanism supports a new generation of communication network services to realize the goal of optimizing the quality of services in an Inter-Cloud system. This work analyzes the proposed load-balancing mechanism in an Inter-Cloud computing system. First, it analyzes the overloading of the cloud provider with an agent-based manager mechanism. Based on the results, the agent-based manager mechanism reduces the loading of the overloaded cloud and provides services to users with another quality of service cloud. Second, this work analyzes the proposed CSLA (Cloud Service Level Agreement) scheduling. Based on the results, the proposed CSLA scheduling balances the loadings of the OpenFlow-based SDN switches and improves the route utilization by 6.4% and 10.8% achieved using Dijkstra routing and Single Path routing mechanisms .
