Incorporated scheduling strategy for streaming media based on popularity

Abstract

Stream scheduling strategy used in streaming media server can improve largely system service capability by increasing system efficiency and reducing bandwidth requirement. In this study, an incorporated scheduling strategy, which combines period-patching and batching scheduling strategy, is proposed. It uses period-patching scheduling to transmit the group-broadcasting streams, and then incorporates the nearby patching streams in a shared patching stream. The bandwidth resource and Qos of system can be improved at the expense of a little longer average waiting time. The simulation results show that incorporated scheduling strategy is more efficient and economical, in aspect of patching stream number and bandwidth requirement, than the typical period- patching scheduling under the circumstances of high visiting frequency for media resources or bursts of rapidly occurring events of user requests.
