摘　　要：从网络吞吐量、磁盘读写性能等关键指标上分析了流媒体集中存储的需求,并以此为基础设计实现了一种流媒体集中存储系统。结合实现过程中遇到的问题,着重围绕存储进程的管理模式、索引的建立、存储文件的分配与调度、存储介质的保护等几个关键点展开了讨论。Some key indicators, such as network throughput and disk I/O performance, are measured for analyzing the needs of centralized streaming storage system. On this base, a kind of centralized streaming storage system is designed and implemented. Combined with problems encountered during the implementation, the following key points are discussed with emphasis： process management, indexes building, flies allocation and scheduling, storage media protection.
