摘要: 通过运用网格技术, 建立一个分布式、海量的教育资源库, 为远程教育过程中的用户提供
一个高效数据共享、有效管理的虚拟教学信息空间。远程教育网格使用网络服务描述语言对系统服务
进行描述, 结合学习对象的概念和远程教育的特点, 分别定义了三种网格服务: 学习对象存储服务、学
习对象检索查询服务和学习对象注册服务。通过在Linux 多机环境下搭建一个用户注册-登陆-使用-注
销的测试环境, 对远程教育网格的基本工作流程进行测试。

Abstract:As a typical case of information service grid in educational area, e-learning grid adopts grid technology to set up a
distributed mass educational resource environment. Distance learning users treat this as a high data sharable and effective manageable
virtual educational space. E-learning grid uses web service description language to describe system bining the concept
of learning-objects and characteristic of distance learning, system defines three grid services: learning-objects repository service,
learning-objects storage-retrieval services and learning-objects Registry service. An experimental system with Linux multi-host of
e-learning grid, which provides the service of user register-log in-usage-log out, illuminates the basic flow of e-learning grid.
