摘　　要：针对流媒体服务高并发的要求,以及无线网络高误码率的特点,设计了一个采用TCP传输的"集中—分布式"无线流媒体服务器系统,并对设计进行了理论分析和实践检验,测试结果证明,该设计架构合理,可扩展性好,并发性能高,传输质量较为可靠,能够很好满足一类无线流媒体应用的需求。To meet high concurrency requirement of streaming service and overcome the high loss ratio of the wireless channel, a wireless video streaming server system was proposed with hybrid centralized-distributed architecture which adopts TCP transmission mode. Theoretical analysis and experimental evaluation results show that the proposed scheme exhibits reasonable scalability, high concurrency and reliable transmit quality. Therefore, the proposed scheme is able to provide good service for one kind of wireless streaming applications.
