基于开源架构的流媒体静态集群应用研究

Study on Application of Streaming Media Static Cluster Based on Open Source Architecture

基于NRM的单个流媒体直播服务器能够承载的并发数量是有上限的,无法满足日益增加的课程直播的需求,更存在安全隐患。通过研究流媒体服务器之间的静态转推和回源操作,划分源服务器和边缘服务器的逻辑业务,完成了流媒体静态集群的设计与实现。在流媒体静态集群中,管理者可以通过调整服务器数量实现灵活伸缩直播平台整体负载能力目的,达到高并发性、高稳定性和高安全性目的。

The number of concurrency that a NRM-based single streaming media live broadcast server can carry is limited,which cannot meet the ever-increasing demand for live broadcast of courses,and there are hidden security risks.In this paper,by studying the static reposting and returning to source operations between streaming media servers,and by dividing the logical business of the source server and the edge server,the design and implementation of the streaming media static cluster is completed.In a streaming media static cluster,the administrator can flexibly stretch the overall load capacity of the live broadcast platform by adjusting the number of servers,and achieve high concurrency,high stability and high security.
