【摘要】：视频会议是一种及时高效的沟通方式。随着经济全球化的推进,人们迫切需要一种及时性强、表现力丰富的交流手段,以应对随时变化的市场形势。软件视频会议系统因其费用较少、功能强大、使用便捷而广泛应用于商务、教育、医疗等场合。在此背景下,本课题根据项目委托公司的实际工程需求,对基于Red5流媒体服务器的视频会议系统做了研究。基于系统客户端用户的良好体验与数据高效处理的双重使用需求,设计实现了客户端功能。利用RIA实现了独立的客户端应用,提高了系统通讯效率。对各项会议核心功能及辅助功能均进行了界面设计和实现,规划了客户端与服务器之间数据交互的流程和方式。针对多方视频会议对视频参与方的并发要求,对会议系统的服务器端进行了性能测试,对多并发客户端所可能引起的服务器性能瓶颈问题进行了分析和研究,为提高服务器端可承受的并发用户数量,设计并实现了由调度服务器、连接管理服务器和请求响应服务器协同完成工作的集群架构,以期减少服务过程中的中断情况,改善并发性能。对视频会议的客户端功能的逐条测试结果表明本研究所设计实现的视频系统客户端界面功能完整,使用友好性强,与底层系统切合度高,符合客户使用习惯,较好地达到了预期目标。对集群化后的服务器端进行性能测试的结果表明优化后的集群结构有效地克服了多方并发的中断瓶颈问题,集群结构能够明显提升服务器端的并发用户上限,提高系统的用户容量,较好的完成了项目的预期要求和目标。
[Abstract]:Video conference is a timely and efficient way of communication. With the advancement of economic globalization, people urgently need a kind of communication means with strong timeliness and rich expressiveness to cope with the changing market situation at any time. The software video conference system is widely used in business, education, medical treatment and so on because of its low cost, powerful function and convenient use. Under this background, the video conference system based on Red5 streaming media server is studied according to the actual project requirement of project entrustment company. The client function is designed and implemented based on the dual requirements of the system client user's good experience and the data efficient processing. The independent client application is realized by using RIA, and the communication efficiency of the system is improved. The interface design and implementation of the core functions and auxiliary functions of the conference are carried out, and the flow and mode of data interaction between the client and the server are planned. Aiming at the concurrency requirements of multi-party video conference participants, the performance of the server side of the conference system is tested, and the problem of server performance bottleneck caused by multi-concurrent clients is analyzed and studied. In order to increase the number of concurrent users on the server side, a cluster architecture of scheduling server, connection management server and request response server is designed and implemented in order to reduce the interruption in the service process. Improved concurrency performance. The test results of the client function of video conference show that the video system designed and implemented by this institute has complete interface function, strong friendliness, high fit with the bottom system, and accord with the custom of the customer. The expected goal has been better achieved. The results of the performance test on the clustered server show that the optimized cluster structure can effectively overcome the problem of multi-party concurrency interrupt bottleneck, and the cluster structure can obviously increase the upper limit of concurrent users on the server side. Improve the system user capacity, a better completion of the project's expected requirements and objectives.
