【摘要】：移动课堂是目前一种新的教学方式,学生使用定制的终端应用,访问移动云平台提供的教育资源,并能够分享自己的资源供其他人使用。移动课堂为远程教育提供了方便,用户不再受时间和地域的限制,能随时随地接触到学习资料,使得无处不在的学习成为可能。在移动课堂中,资源以音、视频等多媒体文件为主,这些资源具有形象生动的特点,能够起到很好的教学效果。但是这类资源的存储通常需要较大的磁盘空间,在传输过程中会需要占用较多的带宽资源,大部分的流媒体应用都是使用流媒体服务器来支持多媒体内容的传输和播放。目前,有很多成熟的流媒体服务器,Red5是其中一款效率较高的开源的流媒体服务器,Red5集成了Java开源框架,保证了应用的高效,开发简单。基于Red5流媒体服务器完成移动课堂中的流媒体平台的开发,实现资源的播放,共享和资源的数字版权保护,在功能实现的基础上,进行平台优化,搭建服务集群,在集群的基础上增加代理缓存机制,并搭建集群的负载均衡服务器,使其能够承载更多的用户连接,并保证流媒体平台具有较好的服务响应时间。最后,对流媒体平台的功能进行总结,分析存在的问题,对以后的发展进行展望。
[Abstract]:Mobile classroom is a new teaching method at present. Students use customized terminal application, access educational resources provided by mobile cloud platform, and share their own resources for others to use. Mobile classroom provides convenience for distance education. No longer limited by time and region, users can access learning materials anytime and anywhere, making it possible to learn everywhere. In the mobile classroom, the resources are mainly multimedia files, such as audio and video. These resources have vivid features and can play a good teaching effect. However, the storage of these resources usually requires large disk space. Most streaming media applications use streaming media servers to support the transmission and playback of multimedia content. At present, there are many mature streaming media server, Red5, which is one of the most efficient open source streaming media servers, which integrates the Java open source framework and ensures the high efficiency of the application. Development is simple. Based on Red5 streaming media server to complete the development of streaming media platform in mobile classroom, to realize the resource playing, sharing and resources digital copyright protection, on the basis of the realization of the function, the platform is optimized, and the service cluster is built. The proxy cache mechanism is added to the cluster and the load balancing server of the cluster is built so that it can carry more user connections and ensure that the streaming media platform has better service response time. Finally, the function of streaming media platform is summarized, the existing problems are analyzed, and the future development is prospected.
