【摘要】：視頻會議是一種及時(shí)高效的溝通方式。隨著經(jīng)濟(jì)全球化的推進(jìn),人們迫切需要一種及時(shí)性強(qiáng)、表現(xiàn)力豐富的交流手段,以應(yīng)對隨時(shí)變化的市場形勢。軟件視頻會議系統(tǒng)因其費(fèi)用較少、功能強(qiáng)大、使用便捷而廣泛應(yīng)用于商務(wù)、教育、醫(yī)療等場合。在此背景下,本課題根據(jù)項(xiàng)目委托公司的實(shí)際工程需求,對基于Red5流媒體服務(wù)器的視頻會議系統(tǒng)做了研究。 基于系統(tǒng)客戶端用戶的良好體驗(yàn)與數(shù)據(jù)高效處理的雙重使用需求,設(shè)計(jì)實(shí)現(xiàn)了客戶端功能。利用RIA實(shí)現(xiàn)了獨(dú)立的客戶端應(yīng)用,提高了系統(tǒng)通訊效率。對各項(xiàng)會議核心功能及輔助功能均進(jìn)行了界面設(shè)計(jì)和實(shí)現(xiàn),規(guī)劃了客戶端與服務(wù)器之間數(shù)據(jù)交互的流程和方式。 針對多方視頻會議對視頻參與方的并發(fā)要求,對會議系統(tǒng)的服務(wù)器端進(jìn)行了性能測試,對多并發(fā)客戶端所可能引起的服務(wù)器性能瓶頸問題進(jìn)行了分析和研究,為提高服務(wù)器端可承受的并發(fā)用戶數(shù)量,設(shè)計(jì)并實(shí)現(xiàn)了由調(diào)度服務(wù)器、連接管理服務(wù)器和請求響應(yīng)服務(wù)器協(xié)同完成工作的集群架構(gòu),以期減少服務(wù)過程中的中斷情況,改善并發(fā)性能。 對視頻會議的客戶端功能的逐條測試結(jié)果表明本研究所設(shè)計(jì)實(shí)現(xiàn)的視頻系統(tǒng)客戶端界面功能完整,使用友好性強(qiáng),與底層系統(tǒng)切合度高,符合客戶使用習(xí)慣,較好地達(dá)到了預(yù)期目標(biāo)。對集群化后的服務(wù)器端進(jìn)行性能測試的結(jié)果表明優(yōu)化后的集群結(jié)構(gòu)有效地克服了多方并發(fā)的中斷瓶頸問題,集群結(jié)構(gòu)能夠明顯提升服務(wù)器端的并發(fā)用戶上限,提高系統(tǒng)的用戶容量,較好的完成了項(xiàng)目的預(yù)期要求和目標(biāo)。
[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.
