Abstract：Current stream scheduling algorithms have to compromise their performance in heterogeneous environments. A Reconfigurable Streaming Media Scheduling (RSMS) algorithm supporting user heterogeneity is proposed. The algorithm by using catching-up streams supports heterogeneous users reconfiguring catching-up streams at different transmission rates and achieves resources sharing ultimately through stream merging. The optimal multicast interval, the average server bandwidth and server bandwidth distribution for RSMS algorithm are all analyzed. The efficiency and scalability of RSMA algorithm are verified through simulation experiment.
