摘　　要：受到网络带宽、服务器性能等因素的影响,现有的视频会议系统在保证视频质量的前提下难以支持大规模会议。同时视频会议室的大小和与会人数不能很好地匹配,造成资源的浪费。针对以上问题,通过分析视频会议系统OpenMeetings的流媒体采集和编码能力及其可能带来的网络带宽瓶颈,提出了一种基于云平台OpenStack的云会议系统解决方案,并将该方案成功地进行了部署。该系统能很好地解决会议规模、带宽瓶颈、资源浪费等问题,并可以提高用户的满意度。Under the influence of factors like network bandwidth and server performance, it is difficult for the existing video confereneing systems to ensure the video quality of large-scale meeting. Moreover, the size of the video conference room and the number of participants cannot be well-matched, which results in a waste of resources. To solve these problems, the acquisition and coding ability and potential bandwidth bottleneck of OpenMeetings were analyzed. A virtualization solution was proposed on the basis of OpenStack cloud platform and finally the solution was deployed successfully. The system can solve the issues like the scale of the meeting, the bandwidth bottleneck and waste of resources to improve user satisfaction.
