Service composition is a useful technology to achieve dynamic requests. But in cloud, the cloud provider should guarantee the QoS of the user request as well. Previous work investigated how to select proper available replicas (the similar functional services located on different physical nodes) to effectively achieve the composite services. However, as the requirements for some service grow, even...
Providing continuous on-demand streaming services with VCR functionality over ubiquitous environments is challenging due to the stringent QoS requirements of streaming service as well as the dynamic characteristics of both underlying network and user behavior. In this paper, we propose SkipStream, a skip graph based peer-to-peer (P2P) on-demand streaming scheme with VCR support to address the above...
Multimedia applications are becoming more and more popular on today's Internet. Given the enormous development costs and less flexibility, traditional monolithic based approaches are not suitable for building large-scale multimedia systems. By composing of distributed, autonomous services dynamically to provide more complex tasks, service composition provides an attractive way for building large-scale...
