基于Swift的教育资源共享平台的设计与实现-计算机系统结构专业论文.docxVIP

摘 要 自 2000 年起国家大力发展教育资源建设。而当今教育资源的重复建设、教育 资源利用率低、教育资源管理难度增大等问题比较严重。通过设计并实现教育资 源共享平台试图解决上述问题。 在引入云计算相关技术的基础之上，分析教育资源共享平台需求；设计平台 整体框架；结合使用 OpenStack 的 Swift 和 Keystone 组件提供私有云存储服务； 使用 SSH 框架开发平台应用；设计并实现应用服务器同 Swift 服务器间的通信模 块；封装底层调用为顶层应用提供易用 API 以方便应用开发；设计并实现教育资 源共享方案；在基于复杂网络的资源有哪些信誉好的足球投注网站模型基础之上实现资源有哪些信誉好的足球投注网站算法；设计 并实现平台的资源处理模块、博客模块、圈子模块、用户管理模块等。 最后部署平台并使用 Apache 提供的 Flood 工具对服务器负载进行测试，测试 结果表明服务器能满足一般需求，性能存在优化提升空间；改进资源有哪些信誉好的足球投注网站算法实 现并对改进效果进行分析。 关键词：教育资源共享 Swift 存储 复杂网络 ABSTRACT The construction of education resources has been vigorously developed since 2000. However, the problems of redundant development, underutilization of education resources and increasing difficulty of maintaining education resources are very serious. There is a solution to these problems by designing and implementing the educational resource sharing platform. The mainstream technology of cloud computing technologies has been studied and the requirement analysis of the platform has been done, and then the framework of the platform is designed. With the combination of the Swift and the Keystone component of OpenStack, the private cloud storage service is provided. By using SSH framework,the web application is developed. The modules which are responsible for the communication of Swift server and application server are designed and implemented. Simple API for the top level application is provided by the encapsulation of the low-level call. The schema of educational resources sharing is also designed and implemented. The searching algorithm based on the search model for educational resources of the complex network is put forward and achieved. The modules of resource handling, blog, group, user management on this platform are designed and carried out. Finally, with the Flood provided by Apache, the server is tested, and the result indicates that the server meet the general requirements, but the server performance can be improved. The implementation of resource search algorithm is optimized and the improving performance is ana
