Services composition can reorganize a variety of heterogeneous network services to form new businesses on multi-service streaming media system, which can speed up the development and deployment of new Services. In this paper, a three layer model is used to describe the service composition in a streaming media system. In order to improve the real-time request response performance, service composition...
Based on stochastic switching model, an event-driven dynamic load balancing strategy is presented for the streaming media clustered server systems. This strategy increases the server cluster availability by balancing the workloads among the servers within a cluster. Additionally, it improves the access hit ratio of cached files in delivery servers to alleviate the limitation of I/O bandwidth of storage...
For a class of hierarchical unstructured P2P systems, a Markov Switching-Space model is introduced to describe their behavior of dynamic grouping. It is also formulated as a optimization problem based on Markov Decision Processes. And parameterized gradient algorithms are provided to optimize the performance, where two parameter reductions are mentioned. Following them are the corresponding simulations...
