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...
The growing popularity of hosted storage services and shared storage infrastructure in data centers is driving the recent interest in resource management and QoS in storage systems. The bursty nature of storage workloads raises significant performance and provisioning challenges, leading to increased infrastructure, management, and energy costs. We present a novel dynamic workload shaping framework...
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...
Policy based resource management will form the cornerstone of service differentiation that will drive IMS service deployment. While the IMS specifications are largely finalized, the policy based QoS provisioning architecture still faces many deployment challenges including flexible, application driven policy control, end to end policy provisioning and policy refinement. To accelerate the maturity...
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...
Beyond 3G wireless systems will support real time and elastic traffic over a common packet-switched radio channel using QoS mechanisms. This paper studies the key question of how to estimate the throughput performance of "best effort" elastic traffic when it is subject to available capacity variations due to changes in (i) the amount of higher priority traffic and (ii) the radio channel...
A content delivery network (CDN) is expected to provide high performance content delivery, which requires scalable infrastructure to achieve global coverage. The provision of such infrastructure may form a substantial entry barrier for new CDN providers, as well as affecting commercial viability of the existing ones. Peering of CDNs can be a way to allow dynamic infrastructural cooperation between...
