碩士 === 國立政治大學 === 資訊科學學系 === 92 === The advance in communication and information technology and impact of telecommunication liberalization cause a revolution in telecommunication world. It attempt to merge circuit-switching and packet-switching network into one standalone perform. All-IP is one of those candidates. But All-IP also inherit the characteristics of packet-switching network, the problem of transmission quality. So, we need some management system of quality on All-IP network to achieve the ambition of converged network. In this thesis, we propose BBQ management system. BBQ offers a highly adaptive management architecture and some management tools for operators. Those tools can be used in different underlying network layer and can tune network by different network policy. We propose an End-to-End QoS solution in BBQ management system. By the concept of bearer services, we separate the End-to-End service into Backbone and Stub Network bearer services. According to the hierarchical management, we propose an approach for resource and path planning in order to enhance network efficiency and provide End-to-End path with QoS in real time. Because Backbone Network is connected by Core Networks and each Core Network plans its internal path independently, End-to-End path planning is to choose Core Networks to pass through. This scheme could reduce the enormous computation and fit for real time path setup. The key point of path planning is how to choose the better Core Network path to compose End-to-End path with QoS and reach efficient resource utilization.
