In the service-oriented architecture, component services can be composed to provide value-added services. The notion of composite service skyline facilitates obtaining a QoS-optimal service combination. State-of-the-art approach to computing composite service skyline assumes that candidate services of different tasks are independent. However, real-word services are usually QoS-correlated. To this...
With the development of mobile network technology, HTTP mobile steaming is deployed by most of the video websites. Thus a lot of research works have been done on the Quality of experience (QoE) evaluation for HTTP mobile streaming. However, in most of them, only the factors in the network layer was considered, and the important information about user dissatisfaction with the video quality may be ignored...
With wide adoption of chip multiprocessors (CMPs) in modern computers, there is an increasing demand for large capacity main memory systems. The emerging PCM (Phase Change Memory) technology has unique power and scalability advantages and is regarded as a promising candidate among new memory technologies. When scheduling a mix of applications of different priority levels, it is often important to...
Service oriented management are focused on service quality rather than network performance. Evaluation based on customer perception of service quality is playing a very important role in service supporting and management. Effective evaluation of service quality can help service provider to increase customer satisfaction. In this paper, we propose three layers evaluation architecture and give the analysis...

The current network management makes the service provider shift from the backend to frontend in order to provide the user satisfactory service. It also leads to the researchers pay the more efforts on the study of integration of QoE and QoS, which provide a better analysis of the service management from the user perspective and from the network perspective respectively. In order to ensure the quality...
