摘　　要：随着HLS、Smooth Streaming等HTTP流媒体技术的不断普及,以及用户访问量、访问密度的不断增长,视频服务器的分发能力将面临严峻的挑战,存储的I/O速度便成为视频服务器分发能力的瓶颈之一。通过对视频服务器的存储研究,以Microsoft IIS Media Services 4.1为例,提出了一种基于Ramdisk的多屏视频服务器优化方法,并讨论了其可行性和适用范围。With the growing popularity of HLS,Smooth Streaming and other HTTP streaming media technologies,andthe increasing of visitors and access density,the distribution capability of video servers are facing serious challenges. I/Ospeed has become one of the bottle necks of memories. Taking video server in Microsoft IIS Media Services 4.1 as an example,this paper presents a Ramdisk-based optimization method for multi-screen video servers and discusses its feasibility andapplication scope.
