摘　　要：随着宽带技术和业务的发展以及人们对视频通信需求的增长,视频通信业务和技术得到了大规模的发展。首先比较了目前各种实现方案的特点和不足;然后基于内容分发网络技术及系统,提出了一种低成本、高扩展性、高质量视频通信的系统方案,详细叙述了该方案的结构、流程及特点;最后给出了验证系统的初步结果。With the development of broadband network technology and service, as well as the increasing of people＇s requirement to video communication service, video communication technology has been studied quickly. In this paper, firstly the characters of current video communication solutions had been studied and compared. Then we proposed one solution of video communication based on content delivery network technology and system, which has low system cost, better scalability and higher video quality. Also the architecture, processing and advantage analysis of this system were described in this paper. Lastly we developed one testing system in real network, and got some initial results.
