With the growing number of service application, need for service platform has appeared. Various solutions were proposed to serve the applications through the existing physical network. Service overlay network is one of the solutions that provide application adaptations and service reliabilities. With this solution, we propose an architecture that composes a service overlay network dynamically to adapt...
On the base of research on congestion control, a flow control mechanism in video-on-demand system is proposed by introducing client buffer analysis. Congestion control and client buffer control were combined to adjust the sending rate adaptively. In this mechanism, all complex operations of traffic control were carried out at the clients, reducing the burden of the video server, allocating the network...
Web services are an emerging Internet technology to dynamically describe, discover and communicate. With the rapid development of the Web services, how to provide quality of service (QoS) becomes a key factor to achieve success in business. This paper proposes a QoS-based Web service composition approach, illustrates the study of related technology in the Web service composition, provides the QoS-based...
As the next generation networks promise to provide network convergence with services for both static and mobile networks, the recent research focus is converging in the direction of standardizing common infrastructure based on all-IP networks. IMS is a recent initiative, designed by 3GPP and TISPAN partnership, which outlines a service delivery platform (SDP) framework. A flexible and robust QoS management...
