大数据时代下开放教育视频云资源共享系统的设计研究

Design and Research of Open Education Video Cloud Resource Sharing System in the Era of Big Data

本文在大数据时代下,对开放的教育视频云资源共享系统的设计进行了研究。构建的教育视频云资源共享系统包括教育视频云资源展示模块、后台管理模块、个人空间模块、视频资源转码模块、视频格式转换模块等。系统运作流程包括匹配信息源、描述信息源、发布信息源、调度信息源。系统的数据库服务器中使用的是Mysql数据库,应用服务器选用tomcat,最后选择JBoss来成为我们系统数据库的负载均衡。而具体大数据时代下对该系统进行访问的流程主要如下所示:提出访问申请仙贝云控制器进行接收,将该访问申请传递到正确地址,严格依照规范负载均衡策略,通过负载均衡服务区,请求被转发到具体虚拟机上实现交互。

In the era of big data,this paper studies the design of open educational video cloud resource sharing system.The educa-tional video cloud resource sharing system includes educational video cloud resource disjDlay module,background management module,personal space module,video resource transcoding module,video format conversion module and so on.The system operation process includes matching information sources,describing information sources,issuing information sources,and scheduling information sources.The system database serer uses Mystql database,the application server uses Tomcat and JBoss as load balancing.Various access requests usually arrive at the cloud controller first,and the access requests are mapped to the correct address.According to the pre-specified load balancing strategy,the requests are forwarded to the specific virtual machine to achieve interaction through the load balancing server.
