计算机远程自动考试系统的改进

Improvement on Remote Test System

本文针对基于C/S结构的计算机远程考试系统存在的问题,采用三层分布式设计方法,对系统的整体结构进行了改进,降低了系统考试中心服务器的负载,提高了网络服务质量,改善了考试的运行环境,同时给出了系统改进当中用到的一些关键技术。

There are some problems in a remote test system based on Client / Server, this paper presents a method by use of tree-layer distributing design to improve the whole systemic structures. The improvement lowers Loads of centre server of system, enhances QoS of network,and amends running environment of test. The paper also gives some key technolgies and algorithms about systemic improvement.
