Abstract

E-Learning systems that enable students to study by themselves without a teacher have widely deployed in universities, high schools and companies. Such an e-learning system is usually implemented as a client-server model. The client-server model, however, has problems with fault tolerance and concentration of system resources such as computation and storage. These problems can be solved by the installation of high-performance servers. These solutions, however, require many costs to purchase high-performance servers; it is difficult to purchase them because of a limited budget. In this paper, we propose a distributed e-learning system that utilizes idle resources of computers in an organization. Many computers in organizations are used for office works, and their computers have excessive computational power and storage space. Thus, we try to utilize such computation and storage of these computers as idle resources. Since our proposed system uses these idle resources, our e-learning system enables us to realize high fault tolerance and a load balancing function without any additional costs.

利用空闲资源的分布式电子学习系统的构想
使学生在没有老师的情况下自主学习的电子学习系统已广泛应用于大学、高中和公司。这样的电子学习系统通常以客户机-服务器模型实现。然而,客户机-服务器模型在容错和系统资源(如计算和存储)集中方面存在问题。这些问题可以通过安装高性能服务器来解决。然而,这些解决方案需要花费很多成本来购买高性能服务器;由于预算有限,很难购买。本文提出了一种利用组织中空闲计算机资源的分布式电子学习系统。组织中的许多计算机用于办公工作,他们的计算机具有过大的计算能力和存储空间。因此,我们试图利用这些计算机的计算和存储作为空闲资源。由于我们提出的系统利用了这些空闲资源,我们的电子学习系统使我们能够在没有任何额外成本的情况下实现高容错性和负载均衡功能。
