【摘要】 为支持教学资源共享,在"国家精品课程集成项目"的支持下,研发了精品课程资源共享平台。目前,精品课程资源共享平台建设了分布在全国东、中、西部5个重要城市的服务节点,收集了分布在31个省、市、自治区高校各学科的千余门精品课程。面向精品课程资源管理及共享的需要,精品课程资源共享平台包含了数据管理及课程视频点播系统。数据管理采用联邦机制,分节点动态地对本地数据资源进行更新。课程视频点播系统引入了混合分布式架构,以便有效管理服务器的加入和退出,实现服务器的负载均衡调度。目前该平台已投入运行。更多还原

【Abstract】 For the purpose of sharing resources of courses,funded by Integration Project for National Excellent Courses,we developed a platform for sharing excellent courses.Currently,the service nodes of platform are distributed in 5 important cities of east,central and west of China.And more than one thousand excellent courses from colleges of 31 provinces have been collected and shared.The platform is consisted of data management and P2P video on demand system.Data management employs federation mechanism and each member in the federation updates data dynamically so as to keep data consistent with other members.P2P video on demand system introduces a hybrid architecture so that it can monitor the entry and exit of nodes and do Load Balance Scheduling.Now,the platform runs online.更多还原
