摘要
由于其方便易用及可靠性,又得益于网络的普及,基于TCP/IP的视频会议已经成为目前市场主流,因此搭建可靠的视频会议服务器也成为了需要解决的主要需求.视频会议服务器不同于普通的流媒体服务器,视频会议服务器需要较高的实时性,而且其接受的上传/下载速度比要比普通的流媒体下载/在线观看服务器高得多.视频会议服务器的媒体服务器主要负责流媒体的接收保存及同步转发.本文借鉴HDFS的最基本原则,提出了一种可靠的分布式结构用于解决视频会议服务器的媒体存储问题.
For the TCP/IP based video conference has been the main requirement because of its convenience and thanks for the well implemented networks now, building a stable video conference server has been required. Differed from normal video-on-demand servers, video conference server requires more on real-time demands, and it faces higher rate of download and upload. Using the basic principles of HDFS for reference, this essay comes up with a reliable distn＇buted file system for the video conference server.
